Abstract

Dairy farming is an important activity in Brazil and Espírito Santo state, with small properties accounting for 80% of production. Despite of this economic importance, data about quality of the milk produced and the hygienic-sanitary conditions are still scarce. Then, the objective of this study was to evaluate the characteristics of refrigerated raw milk produced in family production units in southern Espírito Santo to verify compliance with Brazilian legal standards. Three collections were carried out in 29 community expansion tanks, for a total of 87 samples of refrigerated raw milk. Analysis of standard plate count (SPC), psychrotrophic bacteria count (PBC), somatic cell count (SCC), titratable acidity, density, fat, total dry extract (TDE), non-fat dry extract (NFDE), residues of antibiotics (β-lactam and tetracycline), cadmium and lead levels were performed. Of the 87 samples, 66% presented non-standard values for SPC, and 38% had non-standard values for SCC. Eighty five percent of the samples presented non-standard results for NFDE, 10.3% for density and 2.3% for titratable acidity. All samples complied with the legislation regarding residues of antibiotics, Cd and Pb levels. These results indicated failures in the raw milk obtainment and storage chain from family production units of southern Espírito Santo, Brazil. Resumo A pecuária de leite é uma atividade importante no Brasil e no Espírito Santo, sendo as pequenas propriedades responsáveis por 80% da produção estadual. Mesmo com essa importância econômica para o estado, dados a respeito da qualidade do leite produzido e das condições higiênico-sanitárias de produção, ainda são escassos. Objetivou-se avaliar a qualidade do leite produzido em unidades de produção familiares, no sul do Espírito Santo, para verificar o atendimento aos padrões legais. Foram realizadas três coletas em 29 tanques comunitários totalizando 87 amostras. Realizaram-se análises de contagem padrão em placa (CPP), contagem de bactérias psicrotróficas (CBP), contagem de células somáticas (CCS), acidez titulável, densidade, gordura, extrato seco total (EST), extrato seco desengordurado (ESD), pesquisa de resíduos de antibióticos (β-lactâmicos e tetraciclina) e presença de cádmio e chumbo. Das 87 amostras, 66% apresentaram valores fora do padrão para CPP e 38% para CCS. Quanto às análises físico-químicas, 85% das amostras apresentaram resultados fora do padrão para ESD, 10,3% para densidade e 2,3% para acidez titulável. Todas as amostras atenderam a legislação quanto a presença de resíduos de antibióticos, teores de cádmio e chumbo. Dessa forma, esses resultados indicam falhas em uma ou mais etapas da cadeia de obtenção e armazenamento do leite cru.

Abstract

Plectranthus amboinicusessential oil (PAEO) has the potential to be used by the food industry as a natural antimicrobial alternative. The study aimed to evaluate the antibacterial activity of PAEO in vitroagainst pathogenic bacteria contaminating food and its potential for action when added to intentionally contaminated beef patties. The composition was determined by GC-MS and GC-FID, and thymol (45.64%) was the main compound present in the PAEO. The minimum inhibitory (MIC) and minimum bactericidal (MBC) concentration of the PAEO was evaluated against five pathogenic bacteria (Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, Pseudomonas aeruginosaand SalmonellaTyphimurium). The MIC of PAEO was the concentration ranges between 0.25 and 2 mg mL −1, and the MBC ranged from 1 to 4 mg mL −1. The anti-adhesion and removal of adhered cell assays indicated significant reductions (P < 0.05) even at concentrations 8x lower than the MIC of PAEO. Beef patties samples were prepared with PAEO concentrations at MIC (2 mg mL −1) and sub-MIC (1 mg mL −1). L. monocytogenesand E. coliwere inoculated individually into the beef patties. Significant reductions were observed with a greater reduction in the 12th day of storage for L. monocytogenes(1.52 log CFU.g −1) and E. coli(0.93 log CFU.g −1) for beef patties with the MIC of PAEO. PAEO has the potential to be applied in meat products. However, the application and interactions of the oil in the food matrix need to be better elucidated.
