This article is about the critical role played by intermediate institutions, coined "meso-institutions," in the implementation of regulation. Building on recent theoretical contributions, it proposes a model that emphasizes the functions and tasks fulfilled by meso-institutions in bridging the gap between the macro-institutional layer at which general rules and norms are established and the micro-institutional layer within which transactions are organized. A comparative approach to the institutional settings designed to secure the safety of raw cow milk in Brazil, Canada and Italy substantiates the analysis. Beyond the variety of institutional "configurations" characterizing these cases, the investigation shows how crucial the implementation by meso-institutions is of otherwise similar norms and rules in determining their effectiveness. Meeting food safety regulations depends on the capacity of meso-institutions to fulfil specific functions, the accomplishment of which can be assessed only through related tasks. Lessons are drawn with respect to efficiency, the trade-off between centralized and decentralized solutions, the impact on the organization of supply chains, and the necessity for public policies to pay special attention to meso-institutions in the design and implementation of food safety regulation.

Milk is a food commodity that Indonesia continues to import in large quantities and continues to increase every year. This happens because demand continues to increase and cannot be matched by domestic production. This study aims to determine the competitiveness of dairy milk in Lekkok District, Pasuruan Regency which is the area with the largest dairy cattle population in East Java through the Policy Analysis Matrix (PAM) method. The analysis shows that the PCR value is -0.54 (

Emerging pollutants (EPs) encompass natural or synthetic substances found in the environment that pose potential risks, but which have only recently been recognized or monitored. EPs consist of various categories, including pesticides, pharmaceuticals, hormones, mycotoxins, and endocrine-disrupting chemicals (EDCs). Through several pathways, EPs can access food, potentially leading to health impacts when safe concentrations are exceeded. Milk, being a highly nutritious food product that is heavily consumed by many consumers of different ages, is a crucial food matrix where EPs should be regularly monitored. In the literature, a large number of studies have been dedicated to the determination of different EPs in dairy milk, employing different analytical techniques to do so. Chromatography-based techniques are the most prevalent means used for the analysis of EPs in milk, demonstrating significant efficiency, sensitivity, and accuracy for this specific purpose. The extraction of EPs from a complex matrix like milk is essential prior to performing chromatographic analysis. This review comprehensively covers relevant research papers on the extraction and subsequent detection and determination of EPs in milk using chromatographic methods from 2018 to 2023.

There have been many analytical methods for natural estrogens in commercial dairy milk samples, but in most of which, only four major estrogens (estrone (E1), 17β-estradiol (E2), estriol (E3), and 17α-estradiol (αE2)) were included. This work developed an effective GC–MS analytical method for simultaneous analysis of twelve natural estrogens in commercial dairy milk sample, in which eight far-less well-known natural estrogens (2-hydroxyestone (2OHE1), 4-hydroxyestrone (4OHE1), 2-hydroxyestradiol (2OHE2), 4-hydroxyestradiol (4OHE2), 16-epiestriol (16epiE3), 16α-hydroxyestrone (16αOHE1), 16-ketoestradiol (16ketoE2) and 17epiestriol (17epiE3)) were included besides the four major natural estrogens. With liquid–liquid extraction and solid phase extraction, twelve natural estrogens in commercial dairy milk could be effectively extracted. The established method showed good linearity (R2 > 0.9991), low limits of detections (LODs, 0.02–0.11 ng/g), as well as excellent recoveries (64–117%) with satisfactory low relative standard deviations (RSDs, 0.8–14.7%). This established method was applied to seven commercial dairy milk samples, and all the twelve natural estrogens were frequently detected except for 4OHE2 without detection in any sample. Our results showed that the concentration contribution ratios of the eight far-less well-known natural estrogens in commercial dairy milk samples contributed to 32–83%, while the corresponding contribution ratios based on estrogen equivalence (EEQ) were 21–62%. This work highlighted the high abundance of the eight far-less well-known natural estrogens in commercial dairy milk based on both concentration and EEQ, which has been neglected for a long time.

Dairy milk holds a prominent position as a widely consumed food, particularly among infants and children. However, it is crucial to address the presence of multiple natural toxic compounds that may co-occur in dairy milk to ensure its safety prior to consumption. Aflatoxin M1 (AFM1), an emerging mycotoxin of interest, is a potential contaminant in the milk of animals who ingest aflatoxin B1 (AFB1). The toxin is regulated in the European Union under Commission Regulation No 1881/2006. Unfortunately, there is a notable lack of data concerning the transfer of various emerging microbial contaminants into dairy milk and, therefore, their natural occurrences. In this study, a simple and sensitive LC-MS/MS method was developed and validated for the quantification of multiple cyanotoxins (microcystin congeners and nodularin) and AFM1 by the main analytical guidelines. Toxins are extracted with methanol 80%, followed by an SPE clean-up step before LC-MS/MS analysis. The LOQ was fixed at 1 µg/L for the nine cyanotoxins and 0.05 µg/L for AFM1. Recoveries were measured between 82.67% and 102%. To the best of our knowledge, there are no other LC-MS/MS methods available for the simultaneous quantification of cyanotoxins and mycotoxins in milk. [ABSTRACT FROM AUTHOR]

The consumption of milk contaminated with antibiotic-resistant bacteria poses a significant health threat to humans. This study aimed to investigate the prevalence of Enterobacteriaceae producing β-lactamases (ESBL, MBL, and AmpC) in cow and buffalo milk samples from two Indian states, Haryana and Assam. A total of 401 milk samples were collected from dairy farmers and vendors in the specified districts. Microbiological assays, antibiotic susceptibility testing, and PCR-based genotyping were employed to analyze 421 Gram-negative bacterial isolates. The overall prevalence of β-lactamase genes was 10% (confidence interval (CI) (7–13)), with higher rates in Haryana (13%, CI (9–19)) compared to Assam (7%, CI (4–11)). The identified β-lactamase genes in isolates were blaCMY, blaMOX, blaFOX, blaEBC, and blaDHA, associated with AmpC production. Additionally, blaCTX-M1, blaSHV, and blaTEM were detected as ESBL producers, while blaVIM, blaIMP, blaSPM, blaSIM, and blaGIM were identified as MBL producers. Notably, Shigella spp. were the dominant β-lactamase producers among identified Enterobacteriaceae. This study highlights the presence of various prevalent β-lactamase genes in milk isolates, indicating the potential risk of antimicrobial-resistant bacteria in dairy products. The presence of β-lactam resistance raises concern as this could restrict antibiotic options for treatment. The discordance between genotypic and phenotypic methods emphasizes the necessity for comprehensive approaches that integrate both techniques to accurately assess antibiotic resistance. Urgent collaborative action incorporating rational and regulated use of antibiotics across the dairy value chain is required to address the global challenge of β-lactam resistance.

ABSTRACT: Concerns about antibiotic resistant infections in the United States have called for reduction of antibiotic use in livestock, including dairy cattle. Although effective in curbing antibiotic use, universal organic dairy farming would be impractical and unattainable due to its high land and premium demands. The US Department of Agriculture's organic certification, which completely eliminates antibiotic use in milk production, also raises animal welfare concerns, as it could discourage the use of antibiotics even to treat indicated diseases. Therefore, a proposed alternative for US consumers is a label indicating the responsible antibiotic use (RAU) – not complete elimination – that would minimize antibiotics more than conventional (unlabeled) milk and maximize animal welfare more than organic milk. Our goal was to determine consumers' (1) self-reported preference and (2) willingness to pay for this hypothetical RAU label of milk relative to existing substitutes in organic and unlabeled fluid milk. We conducted (1) a nationally representative survey of US adults and (2) a randomized non-hypothetical experimental Becker-Degroot-Marschak auction with real money and real milk. Although almost half of the survey participants (48.5%) responded that they would buy a RAU-labeled milk, consumers in the experimental auction refused to pay a significant premium for the milk compared with unlabeled milk (mean willingness to pay (95% confidence interval) per half-gallon: $1.92 ($1.65–$2.19) for RAU-labeled milk versus $1.86 ($1.58–$2.13) for unlabeled milk). These results suggest that consumers' survey-identified preferences for RAU-labeled milk could reflect either social desirability bias or a genuine preference for which, however, consumers simply will not pay a significant premium. The study provides preliminary data for future exploration of marketability of the proposed RAU label in the United States and demonstrates the benefits of using complementary survey and experimental auction approaches to understand the potential market for a new dairy product.

Milk is a food ingredient that is considered main source of nutrition for humans because contains essential substances for the body. Microbial contamination of milk can pose various health hazards to humans. Information regarding trends in microbial contamination and mapping its distribution is still limited. Research continues to develop rapidly with methods of analyzing bibliographic linkages with scientific communication models, data that is increasingly interesting to explore. The data were analyzed using bibliometric methods related to milk contamination in Indonesia. After sorting, 108 suitable articles were obtained. The results of the analysis show the peak of article production. After 2021, there was a decrease in the number of publications, indicating a shift in research direction. International collaboration between countries also looks significant. Key themes such as “probiotics,” “milk yield,” and “lactic acid bacteria (lab)” emerged as dominant focuses in this study. Meanwhile, the theme in the ‘Emerging or Declining Themes’ area, has not yet become main focus, but there is potential for development, and challenges that require further research and innovation. Overall, this review provides insight into research trends, international collaborations, and theme dynamics, eflecting the need for future research to continue to explore and reassess research focus.

Streptococcus agalactiae and Klebsiella pneumoniae are emerging as major milk-borne pathogens. Additionally, resistance to antibiotics of pathogens is of concern. Therefore, this study investigated the prevalence and drug resistance of S. agalactiae and K. pneumoniae in mastitis milk samples and assessed the antimicrobial potential of sodium alginate (G)-stabilized MgO nanoparticles (M) and antibiotics (tylosin [T] and ampicillin [A]) against both of these pathogens. A total of n = 200 milk samples from cattle were collected using purposive sampling, and standard microbiological approaches were adopted to isolate target bacteria. Parametric and non-parametric statistical tests were used to analyze the obtained data. Four preparations, GT (gel-stabilized tylosin), GA (gel-stabilized ampicillin), GTM (tylosin and MgO nanoparticles stabilized in gel), and GAM (ampicillin and MgO nanoparticles stabilized in gel), were evaluated against both bacteria through well diffusion and broth microdilution method. The analysis revealed that 45.24% (95/210) of the milk samples were positive for mastitis, of which 11.58% (11/95) were positive for S. agalactiae and 9.47% (9/95) were positive for K. pneumoniae. S. agalactiae had a significantly higher zone of inhibition (ZOI) than K. pneumoniae against penicillin, tetracycline, and amoxicillin, whereas the opposite was observed against imipenem and erythromycin. All gel (G)-based preparations showed an increase in the percentage of ZOI compared with antibiotics alone, with GTM presenting the highest of all, i.e., 59.09 and 56.25% ZOI compared with tylosin alone against S. agalactiae and K. pneumoniae, respectively. Similarly, in a broth microdilution assay, the lowest MIC was found for K. pneumoniae (9.766 ± 0.0 μg/mL) against GTM, followed by GT, GAM, and GA after incubation for 24 h. A similar response was noted for preparations against S. agalactiae but with a comparatively higher MIC. A significant reduction in MIC with respect to incubation time was found at 8 h and remained until at 20 h against both pathogens. The cytotoxicity of the MgO nanoparticles used in this study was significantly lower than that of the positive control. Overall, this study found that K. pneumoniae and S. agalactiae appeared higher in prevalence and antimicrobial resistance, and sodium alginate-based antibiotics and MgO nanoparticles were effective alternative approaches for tackling antimicrobial resistance.

Human food production is the largest cause of global environmental changes. Environmental benefits could be achieved by replacing diets with a high amount of animal-sourced foods with more plant-based foods, due to their smaller environmental impacts. The objective of this study was to assess the environmental impacts of the three most common plant-based milk alternatives (PBMAs)—oat, soy, and almond drink—in comparison with conventional and organic cow milk. Life cycle assessments (LCA) were calculated by the ReCiPe 2016 midpoint method, in addition to the single issue methods "Ecosystem damage potential" and "Water scarcity index". PBMAs achieved lower impact values in almost all 12 of the calculated impact categories, with oat drink and the organic soy drink being the most environmentally friendly. However, when LCA results were expressed per energy and by the protein content of the beverages, the ranking of the beverages, in terms of their environmental impacts, changed greatly, and the results of PBMAs approached those of milk, particularly with regard to the protein index. The study highlights the importance of considering a broader range of impact categories when comparing the impacts of PBMAs and milk. [ABSTRACT FROM AUTHOR]

Currently, consumption of spontaneously fermented milks is common in Algeria, making it a feasible source of diverse lactic acid bacteria (LAB) with the potential to be used as adjunct cultures to improve quality and safety of fermented dairy products. In this context, to select eligible indigenous strains which could be applied as bioprotective and/or starter cultures, the present study aimed to characterize the genomic variability, biotechnological potential, and safety of thirty-eight LAB isolated from Algerian dairy and farm sources of western Algeria. The isolates were unequivocally identified by 16S rRNA gene and fingerprint-based methods. The following species were identified: Enterococcus faecium (n = 15), Enterococcus durans (n = 2), Enterococcus hirae (n = 2), Enterococcus lactis (n = 1), Lactiplantibacillus plantarum (n = 6), Lactococcus lactis (n = 4), Levilactobacillus brevis (n = 3), Lacticaseibacillus paracasei (n = 3), Lacticaseibacillus rhamnosus (n = 1), and Pediococcus acidilactici (n = 1). Among the strains, three of them, L. lactis LGMY8, Lb. plantarum LGMY30 and Lb. paracasei LGMY31 were safe and showed some valuable biotechnological properties, such as high acidification, proteolytic activity, EPS production, and inhibition of undesirable bacteria that made them powerful candidates to be used as starter.

Semi-intensive dairy systems are prevailing in tropical and subtropical countries that need to be probed for public health concern pathogens. The current study was designed to map trends in prevalence of dairy-originated E. coli, associated risk factors, and altering in-vitro drug susceptibility patterns. A total of n=200 subclinical mastitis milk samples were intended to be collected using purposive sampling method from semi-intensive dairy systems for which n=764 dairy animals (n=440 buffaloes, n=324 cattle) were screened. Standard biochemical and microbiological methods coupled with polymerase chain reaction (23sRNA) were applied to identify E. coli from subclinical milk samples. The study, overall, found a 26.18% (200/764) prevalence of subclinical mastitis and 13.50% (27/200) E. coli from subclinical samples. Among assumed risk factors, lack of use of teat dip (OR=8.26, C.I. = 2.73-24.91), higher age groups (OR=17.87, C.I. = 4.42-72.16), parity number >3 (OR=3.68, C.I. = 1.59-8.49), underweight animals (OR=2.89, C.I. = 1.11-7.53), and mid-lactation (OR=14.94, C.I. = 3.04-73.24) were dominant potential risk factors for E. coli infection. Antibiogram showed 42.86 and 21.43% of E. coli isolates resistant to amoxicillin-clavulanate and oxytetracycline, respectively. It was noted that more than 40% (42.86, 60.87, 57.89, 66.86, and 67.86%) of E. coli fall in intermediate susceptible cadre against 62.5% of tested antibiotics. In conclusion, increasing percentages of E. coli, higher number of potential risk factors, and antibiotic susceptibility inclining towards resistance demands stern compliance in anticipated time to avoid any grave situation.

Staphylococcal mastitis has been reported as a serious dairy disease in various regions around the world. The occurrence of resistant strains in Staphylococcus species to antibiotics has triggered alternative treatment substituting antibiotic usage on the global scene. This study aimed to investigate the presence of antibiotic-resistant genes in Staphylococcal subclinical-mastitis cases present in several regencies of East Java Province, Indonesia. A total of 592 quarter milk samples were collected from 62 farms in the region with high dairy cattle populations in Lumajang, Banyuwangi, Malang, Sidoarjo, Jember, Pasuruan, Probolinggo, and Mojokerto. Subclinical-mastitis samples were screened using the California mastitis test (CMT). Positive CMT samples were grown on the selective Staphylococcus media and tested for their biochemical properties. The polymerase chain reaction was performed to detect the presence of antibiotic-resistant genes in all isolates (Staphylococcus sp) using a specific pair-primer for mecA, blaZ, tetK, and tetM genes. The result showed that about 67% of milk samples were subclinical mastitis in several regencies of East Java. About 17.12% of subclinical mastitis was caused by Staphylococcus species (Staphylococcus aureus, Staphylococcus epidermidis, and other non-aureus Staphylococci (NAS)). The most prevalent region of Staphylococcal subclinical-mastitis was recorded in Jember. However, only NAS species obtained from Mojokerto, Malang, Probolinggo, and Banyuwangi were detected to have a blaZ gene responsible for penicillin resistance. In conclusion, the appearance of the antibiotic-resistant gene in NAS species found in several regencies of East Java can be used as important information to evaluate Staphylococcal subclinical-mastitis treatment.

There is widespread contamination by per- and polyfluoroalkyl substances (PFAS) across the globe, with adverse effects on human and environmental health. For human exposure, drinking water and dietary exposure have been recognized as important PFAS exposure pathway for the general population. Several documented cases of dairy milk contamination by PFAS have raised concerns over this exposure pathway in general. A sensitive method for determination of 27 PFAS in milk was hence modified and applied on raw and processed milk samples from 13 farms across the United States (U.S.). A combination of acid and basic extraction method and ENVI-Carb clean-up achieved recoveries of targeted PFAS between 70 and 141%. The method detection limits (MDL) ranged from 0.8 to 22 ng/L (for 26 PFAS) and 144 ng/L for perfluorobutanoic acid (PFBA). The uniqueness of this method is considered in the targeted screening of a broad range of legacy PFAS, as well as perfluorinated sulfonamide species and fluorotelomer sulfonates. No legacy PFAS were detected in 13 milk samples from regions of concern given local use of biosolids or proximity to fire training areas. Overall, then, the uptake of perfluoroalkyl acids (PFAA) from dairy milk in the U.S. is considered low. [ABSTRACT FROM AUTHOR]

Low-quality dietary patterns impair cardiometabolic health by increasing the risk of obesity-related disorders. Cardiometabolic risk relative to dairy-food consumption continues to be a controversial topic, due to recommendations that endorse low-fat and nonfat dairy foods over full-fat varieties despite accumulated evidence that does not strongly support these recommendations. Controlled human studies and mechanistic preclinical investigations support that full-fat dairy foods decrease cardiometabolic risk by promoting gut health, reducing inflammation, and managing dyslipidemia. These gut- and systemic-level cardiometabolic benefits are attributed, at least in part, to milk polar lipids (MPLs) derived from the phospholipid- and sphingolipid-rich milk fat globule membrane that is of higher abundance in full-fat dairy milk. The controversy surrounding full-fat dairy food consumption is discussed in this review relative to cardiometabolic health and MPL bioactivities that alleviate dyslipidemia, shift gut microbiota composition, and reduce inflammation. This summary, therefore, is expected to advance the understanding of full-fat dairy foods through their MPLs and the need for translational research to establish evidence-based dietary recommendations.

The main objective of modern livestock breeding is to find an efficient and a fast way to increase productivity and quality, and the application of technologies based on DNA markers have a great influence on the livestock and also contributes further to the mapping of the genomes of different species of economic importance. Past decade research carried out at the DNA level had a main goal: to identify the genes responsible for the expression of quantitative characters and the detection of places of interest, the latter becoming markers of DNA or SNP type that can be used in the selection process and improvement programs of dairy farms. In Romania, several studies were performed in order to identify the associations of the genetic markers with the main traits of milk production by Vlaic et al, (2001; 2003; 2005); Creangă et al., (1996, 2002, 2003; 2007, 2008, 2010); Bâlteanu et al., (2007a; 2007b, 2008; 2010a; 2010b, 2013); Bugeac et al., (2013a, 2013b, 2013c, 2015, 2019), respectively for the quality of meat by Carşai et al, (2009, 2010, 2013).

The entire world is committed to maintaining the 1.5 °C global temperature rise target in order to avoid very serious impacts of climate change. However, because the food sector is one of the primary contributors of GHG emissions, the environmental impact of food products is now a new criterion for consumer product selection, and this includes milk. The current review investigates the state of the art of the environmental impact of animal-based milk (ABM) (cow, buffalo, goat, and sheep) and plant-based milk (PBM) (almond, oat, soy, pea, and coconut) systems using 70 milk life cycle assessment (LCA) studies. The critical review aims to produce two primary deliverables concerning the environmental impact of ABM and PBM. The first section is concerned with generating a universal LCA framework for ABM and PBM systems, as well as the recalculation of collated results to standardize and synthesize a full comparison of AM and PBM based on several eco indicators and presents a hierarchy of environmentally sustainable milk. From the synthesis of results, it was observed that the lowest mean of global warming potential (GWP) in ABM is cow milk, and in PBM is coconut milk, i.e., 1.29 and 0.257 kg CO 2 /kg of milk, respectively. The second section highlights the comparative effects of assumptions for LCA system functions i.e., system boundaries and impact allocation methodology, with critical insights. Apart from that, the current review also investigates the hotspots in ABM and PBM systems, presents the priority order of processes for the mitigation measures, and provides multiple mitigation strategies and their effect. The authors also identify challenges and future research areas to make dairy and nondairy milk systems more environmentally sustainable. [Display omitted] • 70 LCA and CF studies were reviewed of animal and plant-based milk (PBM) systems. • The environmental impact of animal and plant-based milk systems was thoroughly compared. • Environmental aspects of the PBM system are relatively unexplored and require rigorous evaluation. • GHG emissions from PBM are low, but water footprints are high compared to cow's milk. • Hotspots of animal milk: enteric fermentation, animal feed, manure, PBM: processing, packaging, transport.

Plant-based milk import has been increasing in the Fijis supermarkets. While this milk may cater for vegans(1) and people with allergies from dairy milk, the question always remains that if the plant-based milk are equally nutritious and available at reasonable price in comparison to the dairy milk. Dairy milk is commonly consumed by the Fijian population while the plant-based milk is positioning itself into the market as alternatives. Therefore, this paper is aimed at comparing the nutrient content and price of milk from dairy cows and plant milk sources available in the supermarkets in Fiji. This study examines different brands of dairy and plant-based milk in 6 major supermarket chains in the central part of Fiji. There was 22 dairy milk, 6 soya milk, 5 almond milk and 4 oat milk sampled from these supermarkets. The median value of milk nutrient composition and price for dairy milks and different plant-based milks were calculated as the data was not normally distributed. The Kruskal- Wallis test was conducted to further analyse the difference between the nutrient composition and price of dairy milks and plant-based milk. The energy composition in the dairy milk was significantly higher (p < 0.01) when compared with plant-based milks soya almond milk and oat. There was a significant difference (p < 0.01) in dairy milk protein, fat and saturated fat when compared to plant-based milks. The result indicated that the protein, fat, and saturated fat are both significantly higher in cow's milk. Milk carbohydrate analysis indicate higher composition in dairy milk therefore a significant difference (p < 0.01) was noted when compared to almond milk(except soya and oat milk). There is a significant difference (p < 0.01) in sugar indicating cow's milk having higher sugar when compared to plant-based milk (except soya milk The sodium composition in the dairy milk and all the plant- based milk showed no significance difference (p > 0.05) in the composition. There was also significant difference (p < 0.05) in comparison of calcium composition of dairy milk and plant-based milk indicating almond milk with lower calcium. The phosphorus composition in dairy milk and plant-based milk indicates that there is a strong significant difference (p < 0.01) (except soya and oat milk). The riboflavin composition was significantly higher (p < 0.01) in dairy milk compared to soya and oat milk. Lastly, there was significant difference (p < 0.01) between price of dairy milk when compared to plant-based milk. The study concludes that there is more nutrient in dairy milk and the price is significantly lower than plant-based milk at which these nutrients are available in dairy milk. [ABSTRACT FROM AUTHOR]

Milk is the result of the livestock subsector which has great potential to be developed in Indonesia. Development of dairy agribusiness is expected to be able to meet domestic milk consumption needs. The purpose of this study is to determine strategies that can be used as an effort to improve the quality of fresh milk, especially production managed by cooperatives. The location of the study was in Galur Murni Dairy Farmer Cooperative (KPGM) which is located in Jember Regency, East Java Province. This research was quantitative descriptive research. The research design deployed was case study to study intensively or deeply from the research target group. The analytical method used consisted of SWOT analysis, which was used to determine alternative strategies of the quality of diary milk production at Galur Murni Cattle Breeder Cooperative. Based on the results of the SWOT analysis, it is known that the alternative strategy that gets the highest weight is Strength Opportunity (SO) of 7.6. The strategies referred to in SO include quality control, increasing the number of experts (recruitment of experts), conducting counselling, and optimizing forage land as forage feed supplies.

Current study focused on resistance modulation of dairy linked epidemic mec A positive S. aureus for resistance modulation by plant extracts (Eucalyptus globolus, Calotropis procera), NSAIDs, and star-like microparticles. Zinc oxide {ZnO} and {Zn (OH)2} microparticles were synthesized by the solvothermal method and characterized by calcination, X-ray diffraction (XRD), and Scanning electron microscope (SEM). Plant extracts were prepared by Soxhlet extraction method. The study found 34% of subclinical samples (n = 200) positive for S. aureus from dairy milk having significant (p < 0.05) association of assumed risk factors with the pathogen. Antimicrobial assay showed 55, 42, 41 and 41% of S. aureus resistant to oxacillin, ciprofloxacin, streptomycin, and enoxacin. Amoxicillin showed the highest percentage of increase in zone of inhibitions (ZOI) at 100 mg of Calotropis procera extract (31.29%) followed by 1 mg/mL (28.91%) and 10 mg/mL (21.68%) of Eucalyptus globolus. Amoxicillin increased ZOI by 42.85, 37.32, 29.05, and 22.78% in combination with 500 µg/ml with each of diclofenac, aspirin, ibuprofen, and meloxicam, respectively. Fractional inhibitory concentration indices (FICIs) showed synergism of amoxicillin with diclofenac and aspirin, and indifferent synergy with ibuprofen and meloxicam. The preliminary in vitro finding of a combination of microparticles with amoxicillin proved to be synergistic giving rise to 26.74% and 14.85% increase in ZOI of amoxicillin in combination with zinc oxide and zinc hydroxide, respectively. The modulated antimicrobial resistance incurred by NSAIDs, plant extracts and microparticles against pathogenic S. aureus invite immediate attention to probe alternative antimicrobial sources.

Objectives: Human milk has been shown to reduce severe morbidity in preterm/low-birth-weight infants and is therefore the recommended nutritional source. When infants cannot receive maternal milk, donor human milk (DHM) is recommended. The use of human milk banking facilities is increasing to meet the need for DHM. DHM is unique compared to maternal milk as it must be processed and stored. The processing and storage of animal milk has been more rigorously studied than human milk and can serve as proxy to create DHM banking guidelines., Methods and Analysis: We will search electronic databases, grey literature, and the websites of relevant international organizations. We will include studies that evaluated the impact of storage, handling, and treatment on the nutritional quality and safety of animal milk. We will not restrict study date, language, or design. If sufficient homogeneity exists between studies, we will conduct a meta-analysis. We will evaluate the methodological quality of each study using the SYRCLE's (Systematic Review Centre for Laboratory Animal Experimentation) risk of bias tool. (1) We will evaluate the overall certainty of the evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach., Conclusion: In this systematic review and meta-analysis, commissioned by the World Health Organization, we will synthesize the available literature regarding the impact of various storage, handling, and treatment practices on the nutritional quality and safety of animal milk., Competing Interests: Dr. Colaizy is the research director of the research committee of the Human Milk Banking Association of North America (HMBANA). She contributes to this position on a volunteer basis and has never received any honorarium from HMBANA. This proposal was not discussed in the research committee of HMBANA, and HMBANA did not have any role in the design of this study.

Introduction: Resistance exercise training (RET) can increase muscle mass and strength, and this adaptation is optimized when dietary protein is consumed to enhance muscle protein synthesis. Dairy milk has been endorsed for this purpose; however, allergy and lactose intolerance affect two-thirds of the global population making dairy milk unsuitable for many. Plant-based alternatives such as soy milk have gained popularity and exhibit comparable protein content. However, concerns regarding soy phytoestrogens potentially influencing circulating sex hormones and diminishing the anabolic response to RET have been raised. This study therefore aimed to assess the acute effects of dairy and soy milk consumption on circulating sex hormones (total, free testosterone, free testosterone percentage, total estrogen, progesterone, and sex hormone binding globulin) after RET., Materials and Methods: Six male participants were recruited for a double-blinded, randomized crossover study with either dairy or soy milk provided post RET. Venous samples were collected before and after milk consumption across seven timepoints (0-120 minutes) where circulating sex hormones were analyzed. Two-way ANOVA analyses were applied for repeated measures for each hormone. The area under the curve (AUC) was also calculated between dairy and soy milk. Significance was set at p<0.05., Results: No significant differences were observed in acute circulating serum for free (p=0.95), % free (p=0.56), and total testosterone (p=0.88), progesterone (p=0.67), or estrogen (p=0.21) between milk conditions. Likewise, no significant differences in AUC were observed between any hormones., Conclusion: These findings suggest that consumption of dairy milk and soy milk have comparable acute effects on circulating sex hormones following RET. Further investigations with expanded sample sizes are needed to strengthen and broaden these initial findings., Competing Interests: The authors have declared financial relationships, which are detailed in the next section., (Copyright © 2024, Craddock et al.)

E. coli is one of the most important food borne pathogen, which could be transmitted by milk and milk products. To assess the role of dairy milk as the source of drug resistant E. coli, we examined 50 raw dairy milk samples (25-farm milk + 25-market milk) from some selected areas of Bangladesh by cultural, morphological, biochemical and antimicrobial sensitivity tests. In the preliminary observation, the mean total aerobic mesophilic count of market and farm raw milk samples were 8.98 and 8.68 log CFU/ml, while mean coliform count were 4.20 and 3.03 log CFU/ml respectively. Thirty-three E. coli isolates were recovered from collected samples (66% 33 of 50) and this pathogen was more prevalent in market milk (76%, 19 of 25) than farm milk (56%, 14 of 25). In addition, most of the isolated E. coli exhibited resistance against ampicillin and cefotaxime. This result shows that, the raw dairy milk and its products could be a source of human drug resistant E. coli.

Throughout the world, more than six billion people consume milk and milk products yearly. The safety and quality of dairy milk are regularly monitored in most countries worldwide. The Israeli monitoring program of chemical residues in milk has not changed in the last decades, focusing only on major veterinary drugs and few selected environmental contaminants such as heavy metals and persistent organic pollutants. Consequently, a knowledge gap exists regarding the potential occurrence of other chemicals such as human pharmaceuticals and non-monitored pesticides in milk. In this survey, 51 commercial bovine and goat milk samples were analysed by LC-MS/MS and pharmaceutical and pesticide residues are reported in the range of 0.1–93 µg/L. Israeli milk samples revealed at least one and up to five chemical residues simultaneously. The pesticides found in milk were below the European maximum residue limit values. The risk assessment performed, indicated negligible risk. [ABSTRACT FROM AUTHOR]

Excessive Ca intakes have been proposed to associate with vascular calcification and a higher risk of prostate cancer. We investigated the associations of supplemental and dietary Ca intake with mortality using data from 497 828 UK Biobank participants. The average follow-up was 4·2 years and 14 255 participants died, 8297 from cancer, 2959 from CVD and 572 from respiratory disease. The use of Ca supplements and milk consumption were associated with differences in mortality in younger (≤65 years) but not in older participants (>65 years, P interaction ≤ 0·04 for all comparisons). Among participants <65 years, there was an inverse association between Ca supplementation (OR 0·91, 95 % CI 0·83, 0·99) and milk consumption (OR 0·93, 95 % CI 0·86, 1·00) with respect to all-cause mortality. In the same age group, milk drinkers had lower odds of cancer mortality (OR 0·89, 95 % CI 0·80, 0·98) but Ca supplement use was associated with increased odds of respiratory mortality (OR 1·69, 95 % CI 1·16, 2·74). All associations in participants aged ≥65 years were null after full adjustment. In sensitivity analyses stratified by hormone replacement therapy, Ca supplement use was associated with decreased odds of cancer mortality in users but increased risk in other women (OR 0·81, 95 % CI 0·69, 0·94 v. OR 1·17, 95 % CI 1·01, 1·35, respectively). To conclude, we saw little evidence for harm with dietary or supplemental Ca. Further studies are required to confirm the proposed interaction with hormone replacement therapy and to exclude reverse causation as a determinant in the association between Ca supplements and increased risk of respiratory diseases.

Background: The effects of plant-based milk consumption on the growth of children are unclear., Objectives: We aimed to evaluate the relationship between plant-based milk consumption and BMI in childhood. Secondary objectives were to examine the association with height and whether these relationships are mediated by dairy milk intake and modified by age or the type of plant-based milk consumed., Methods: A prospective cohort study was conducted in healthy children aged 1-10 y through the TARGet Kids! primary care research network in Toronto, Canada. Linear mixed-effect modeling and logistic generalized estimating equations were used to evaluate the association between plant-based milk consumption (number of 250 mL cups/d) and BMI. A mediation analysis was conducted to examine whether dairy milk intake mediated these relationships. Effect modification by age and type of plant-based milk was explored., Results: Among 7195 children (mean age: 3.1 y; 52.3% male), higher plant-based milk consumption was associated with lower BMI (P = 0.0002) and height (P = 0.005). No association was found with BMI categories. Lower dairy milk intake partially mediated these relationships. A child aged 5 y who consumed 3 cups of plant-based milk compared with 3 cups of dairy milk had a lower weight of 0.5 kg and lower height of 0.8 cm. Associations did not change over time and were similar for children who consumed soy milk compared with other plant-based milks., Conclusions: Plant-based milk consumption was associated with lower BMI and height, but both were within the normal range on average. Future longitudinal studies are needed to determine whether these associations persist over time., (Copyright © 2024 American Society for Nutrition. Published by Elsevier Inc. All rights reserved.)

The fluoride (F) concentrations of 10 brands of cow's milk sold in Iran were analyzed and the exposure to F from milk consumption was calculated. The mean F content of the samples was 0.023 mg/L with a range of 0.014 to 0.04 mg/L. The results of this study showed that the relatively low level of F in commercially available diary milk in Iran would not be expected to cause a significant increase in the daily F intake.

Laser-induced ultrasound detection is a well-known technique for diverse applications, including medical analysis, materials characterization, industrial quality control, and environmental monitoring. The measurement of the speed of sound in liquids is frequently performed using a single-crystal ultrasonic interferometer, a device which requires a substantial volume of liquid (≥10 mL), hindering its utility in low-volume applications (e.g., biomedical screening). Other specialized techniques, such as the transient grating approach, exist and while some provide additional useful information (e.g., thermal diffusivity and damping parameters), they are costly and complex to implement, frequently requiring a specialist. In response to these instrumental limitations, we introduce a simple, inexpensive, and convenient laser-based approach to directly measure the speed of sound in minute liquid volumes (≥25 μL) with a high degree of accuracy (percent relative standard deviation in determining sound speed better than ±0.15%). This new technique, termed laser-induced sound pinging (LISP) owing to the inspiration drawn from submarine sonar pinging, is demonstrated using an inexpensive tattoo-removal Nd:Ce:YAG laser. In this communication, we validate the concept of LISP and demonstrate its unique capabilities by analyzing a variety of samples on the basis of the speed of sound: the salinity of water, dilutions of bovine milk, and the characterization of representative ionic liquids. Given the rapid nature of measurement, ease of operation, simplicity of analysis (model-free), and microliter sample volume requirements, we anticipate that LISP will progress as a beneficial and practically-relevant analytical tool for answering a broad range of liquid forensic questions, with potential applications in drinking water quality evaluation, food safety and authentication, bioanalysis, and quality-control (e.g., measuring sugar contents in soft drinks). Fieldable and real-time, in-line versions of this instrument can also be envisaged in the near future. [ABSTRACT FROM AUTHOR]

Due to the decrease in fluid milk consumption as a beverage in the United States, the importance for dairy industry stakeholders to understand attribute preferences for consumer segments has increased. This paper uses a representative sample of U.S. residents to determine shopping behavior and a Best-Worst experimental design to examine consumer preferences for select milk attributes. The Random Parameters Logit model revealed the largest preference shares were for price (19.1%), fat content (17.6%), and humane handling (16.1%). Segmentation of the respondents was analyzed using a Latent Class Model, and the demographics of segments were analyzed by probabilistic assignment. This contribution, which may be applied to other products, allows for a detailed understanding of consumer preferences for fluid milk. Demographics such as gender and age were not statistically different across the five classes for this topic, unlike shopping behavior. Class 2 was named "The Balancing Act" due to respondents' balance between animal welfare aspects and the physical characteristics of milk. Class 5 was dubbed "Value and Volume" due to large preference shares for price and container size. A lower percentage of respondents in "The Balancing Act" (12.2%) reported purchasing fat-free skim milk when compared to the percentage of respondents in "Value and Volume" (18.6%). Due to the large preference shares for traditional milk attributes, Class 3 was named "Traditional Milk Shoppers." A higher percentage of respondents in "Value and Volume" also reported always reading the information on meat, egg, or milk products when compared to "Traditional Milk Shoppers" (12.2%). Although price is still important to many consumers, certain segments have preferences or demand for other attributes that may be satisfied by producers to increase market share or price premiums.

Postprandial hyperglycemia (PPH) transiently impairs vascular endothelial function (VEF) in an oxidative stress-dependent manner by decreasing nitric oxide (NO•) bioavailability. Dairy milk and its proteins attenuate PPH, but whether this improves VEF is unknown. We hypothesized that dairy milk, mediated by its whey and/or casein proteins, improves VEF by attenuating PPH-induced oxidative stress that otherwise decreases NO• bioavailability. A randomized, cross-over trial was conducted in adults with prediabetes (n=23) who ingested glucose (75 g, GLU) alone or with 473 mL of non-fat dairy milk (MILK) or isonitrogenous (16.5 g) amounts of whey (WHEY) or casein (CASEIN) in 473 mL of water. Prior to and at 30 min intervals for 180 min postprandially, we assessed brachial artery flow-mediated dilation (FMD) and measured biomarkers of glycemic control, oxidative stress, and NO• homeostasis. FMDAUC decreased to the greatest extent during GLU, which was similarly improved in dairy trials. Compared with GLU, AUCs for glucose, malondialdehyde, F2-isoprostanes, methylglyoxal, and endothelin-1 were similarly lower in dairy trials. Plasma arginine and NO• metabolites were greater but methylated arginine metabolites were lower in dairy trials compared with GLU. Postprandial insulin, lipids, and tetrahydrobiopterin redox status did not differ among trials. Thus, dairy milk, mediated by its whey and casein proteins, attenuates PPH-mediated impairments in VEF by limiting oxidative stress. This improves NO• bioavailability to the vascular endothelium by increasing arginine availability and limiting competitive inhibition on NO• biosynthesis by asymmetric dimethylarginine. These findings support observational studies that dairy milk lowers cardiovascular disease risk. [ABSTRACT FROM AUTHOR]

Purpose: Few studies have examined acute cognitive effects of dairy products. Prior work suggests baseline glucoregulatory function may moderate the relationship between macronutrient profile and postprandial cognition. This study examined the role of glucoregulatory function in postprandial cognition after milk, fruit juice, and a water control. We hypothesized juice would improve cognition in those with lower fasting glucose, while milk would improve cognition in those with higher fasting glucose.Design: 86 non-diabetic, non-hypoglycemic young adults attended three 8 AM testing sessions after fasting overnight. Fasting glucose was assessed via fingerstick at each session. Participants consumed 8 oz of 1% milk (12 g carbohydrates), apple juice (29 g carbohydrates), or water in a randomized, counterbalanced order, and completed repeatable standard and running memory continuous performance (SCPT—vigilance; RMCPT-working memory) and go/no-go (GNG-inhibitory control) tasks 30, 90, and 120 min post-ingestion.Results: Participants with fasting glucose above 107.69 mg/dL made significantly fewer GNG commission errors overall after milk versus water, while the converse was observed when fasting glucose was below 70.85 mg/dL (p = 0.003). At 30 min, participants with fasting glucose above 105.80 mg/dL made significantly more RMCPT correct responses per minute after milk versus juice, while the opposite occurred when fasting glucose was below 76.85 mg/dL (p = 0.006). For both tasks, differences greatened as fasting glucose increased or decreased beyond these upper and lower bounds, respectively.Conclusions: Consideration of baseline glucoregulatory function is crucial when assessing postprandial cognition, even in non-diabetic and non-hypoglycemic samples. Dairy milk may improve cognition in persons with higher fasting glucose. [ABSTRACT FROM AUTHOR]

Background: Contribution of dairy milk and other food items and schools to academic performances of students are the important factors to build a peaceful meritorious nation with sound mental and physical health. Objective: This experiment was designed to study the contribution of dairy milk and other food item intake pattern and schools to academic performances. Method: Students of class nine in Bangladesh were enumerated using a preprescribed questionnaire during March 2016 to June 2016 by direct interview method. Collected primary data were analyzed using the Statistical Package for the Social Sciences version 14.015. Results: Male (69.63%) students and students of schools in the town (84.97%) performed better. Majority of the students in towns (46.85%; 49.65%) and villages (45.51%; 50.90%) drank dairy milk and ate meat respectively, once or twice in a week. Many students in towns (30.77%) and villages (38.92%) ate eggs for 3 to 4 days in a week. Maximum students in town (53.50%) and in village (46.71%) took fish for 5 to 7 days and 3 to 4 days in a week, respectively. Many students in town (39.86%) and in village (59.88%) took fruits 1 to 2 days and 5 to 7 days in a week, respectively. Most (74.31%) of the students who took dairy milk, meat (73.68%), fruits (66.67%), fish (65.81%) and eggs (64.71%) everyday in a week obtained A grade. Conclusions: Schools, availability of dairy milk, meat, fruits, fish and eggs, Tiffin intake status and gender affected the academic performances but educational institutions had no effect on weekly dairy milk, eggs and meat intake of the students but weekly fish and fruits intake status were affected.

Milk fatty acid (FA) profiles of lactating Holstein dairy cows were determined to evaluate the effects of parity (primiparous or multiparous) and the grazing time (0,6 and 12 h), complementary to a total mixed ration, in a 2 x 3 factorial design. The interaction of parity with grazing time did not affect milk production and protein content; however, dry matter intake of herbage, total dry matter intake and milk fat content were affected by the interaction (P < 0.05). Both factors affected the milk concentration of monounsaturated FAs. The 18:3 cis9 cis12, 18:2 cis9 trans11, and 18:3 cis9 cis12 cis15 concentrations in milk were higher (P < 0.05) in primiparous cows. Milk 18 : 2 cis9 trans11 concentration in primiparous cows with 12 h grazing (1.17 g/100 g FA) was 44% and 57% higher than with 6 h and 0 h grazing (0.66 and 0.50g/100gFA, respectively). Similar pattern was observed for 18 : 3 cis9 cis12 cis15. The milk 18 : 1 trans11 concentration was higher (P < 0.05) with 6 h and 12 h grazing than without grazing. In conclusion, the parity would appear to mainly affect the proportion of short-chain FAs, and had an important influence on the proportions of 18 : 2 cis9 trans11, and 18 : 3 cis9 cis12 cis15. These FAs and also 18:1 trans11 were modified by grazing time. [ABSTRACT FROM AUTHOR]

Following a well-balanced diet ensures that a person gets all the essential elements for health sustenance. However, in the United Kingdom an increasing proportion of people are transiting to become vegans who exclude animal-based products in their diets. Consequently, people may have a deficit of essential elements such as iodine which is not present in most plant-based meals, additionally iodide fortified table salt is not commonly used in the UK. Without iodine people consuming a vegan diet risk developing iodine deficiency and diseases like goiter. The objective of this study is to determine the difference in iodine content and iodine speciation between plant-based and dairy products. More than 100 market samples of plant-based and dairy milk products were collected in Scotland, UK. Iodine concentrations in dairy milk is ten times higher compared to plant-based milks. Similar differences were also apparent for butter, yogurt and cheese. A total of 20% of plant-based milk products were fortified with iodine, however these products had lower iodine concentrations compare to the equivalent dairy products. In this study we calculated that people with average diet have an iodine intake of 226 + /- 103 μg day−1 from dairy products which satisfies the WHO recommended intake of adults and 90% of the recommend intake for pregnant and breast-feeding women. A diet from substituted dairy products gives only 21.8 µg day−1 for the respective WHO guideline intake values, which accounts only 15% of the iodine intake for adults and 9% for pregnant and lactating women. Iodine fortified diet could increase the iodine intake to 55% or 33% of the WHO recommended daily intake respectively. Plant-based dairy consumers are encouraged to use iodine fortified dairy products or use of iodized salt in the UK for home cooking, otherwise there are at risk to get iodine deficient. [Display omitted] • UK Market survey of iodine in dairy and its plant-based replacement commodities • Adequate daily iodine intake in the UK through diary products. • Vegan-based diet do not benefit from high iodine concentration in dairy products. • Plant-based dairy products contribute 15% of recommended daily intake for iodine set by WHO for adults.
