Highlights • The paper reports for the first time Alaria alata mesocercariae in domestic pigs in Serbia. • This is the only reported case in domestic pigs over the past several decades in Europe. • Increasingly popular free-range pig farming may create a risk to animal and public health of alariosis. • The results should influence the growing awareness of alariosis as a potential human disease. • The results may serve as a reason for reconsideration of the appropriate regulations. Abstract Alaria alata (Diplostomidae, Trematoda), a potentially zoonotic pathogen, is the only Alaria species in Europe. In recent years, increasing reports of mesocercariae of A. alata in wild boars have been recorded in European countries; however there have been no described cases in domestic pigs over the past decades. Out of 272 diaphragm samples from wild boars (Sus scrofa) and domestic pigs (Sus scrofa), from Serbia, included in the present investigations, mesocercariae of A. alata were found in six (3%) samples from wild boars and in two (2.77%) samples from domestic pigs. Due to the lack of sensitivity of artificial digestion with a magnetic stirrer which was applied in the study, the true prevalence is estimated to be considerably higher in the area of investigation. Confirming the infection in domestic pigs and a wide distribution in wild boars in the area of investigation, the present paper should influence the growing awareness of alariosis as a potential human disease. The meat from free-range domestic pigs and game meat as a potential source of alariosis should always be adequately thermally treated before consumption. [ABSTRACT FROM AUTHOR]

Food chain information (FCI) refers to information that is gathered along the food chain for animals intended for slaughter and is exchanged between the stakeholders at the different stages of production. FCI includes, for example, information on veterinary medicinal products or other treatments administered to the animals within a relevant period (RP) and with a withdrawal period greater than 0 days according to Regulation (EC) No 853/2004. Since the EU regulation does not specify which exact data should be collected, there are different definitions of the RP and different forms for collecting FCI across Europe. As a consequence, the information content of FCI has become heterogenous. Our study aimed to gather FCI report forms and the definitions of RPs from 35 European countries via an expert survey. Our research showed that the time frame for the RPs ranges from 0 days to the entire fattening period for all three species across Europe. For pigs and bovines, there is no clear consensus on a meaningful time frame for the RP. However, for broilers, in most European countries the RP covers the entire fattening period. Thus, harmonising the RP to the entire fattening period for broilers should be considered across the EU. Further research is necessary to determine appropriate RPs for pigs and bovines. In the case of bovines, RPs should vary depending on production types. Establishing an animal health database and transitioning from paper-based to electronic FCI transmission could standardise RPs and bring data harmonisation. Currently, the various FCI forms have different structures and request differing information. While our study did not aim to identify the optimal parameters, we advise against using forms that only require a signature stating that there is no data that could affect meat safety. Instead, farmers should provide relevant data or answer yes-no-questions. Additionally, improving and modernising FCI should also include educating and training those who work with it daily. Reporting meaningful information and subsequent action at the abattoir are crucial to achieving the intended purpose of FCI as part of risk-based meat safety assurance systems. • Unspecific EU Regulation led to different content of FCI in Europe. • There are various FCI forms across Europe; either species-specific or covering all. • Type and amount of information reported via FCI are dissimilar between countries. • For broilers, the relevant period mostly covers the entire fattening period. • The defined relevant periods for pigs and bovines are very inconsistent.

Comprehensive identification of on-farm animal-health issues still requires extensive efforts so that in practice such monitoring is applied only sparsely. An appealing approach to improve on-farm animal health and welfare monitoring is the application of organ lesion scoring data from the abattoir as such is instantly available for every commercial farm in Europe. Unfortunately, it is also well-known that organ lesion scoring is often unreliable because results are altered by several non-health-related factors, diluting the validity of lesion scoring prevalence as a proxy for on-farm animal health. However, it is theoretically possible to improve prevalence reliability a-posteriori by application of time-series smoothing. The aim of this paper was therefore to analyse whether it is practically possible to increase apparent prevalence estimation reliability retrospectively using a running average, and, if so, which window length and smallest sample size should be preferred in such an approach. Because no gold standard for direct evaluation of lesion reliability is available for field-data, apparent prevalence reliability had to be approximated using prevalence agreement over time. Results indicate that by raising the number of lesion scores per prevalence estimate, apparent prevalence agreement over time can in general be considerably increased. Based on findings presented, a reasonable threshold for prevalence estimation is given by at least n = 50 lesions per farm/abattoir/time-series segment. Results further suggest that it is necessary to consider differences in prevalence sample size for future monitoring purposes, because prevalences that are estimated on a continuum of different sample sizes put together in one evaluation may induce substantial error in prevalence estimates.

PIGCAS (Attitudes, practices and state of the art regarding piglet castration in Europe) is to our knowledge the first project that has focused on castration practice across European countries (European Union minus Bulgaria, Malta and Romania, plus Norway and Switzerland). About 250 million pigs are slaughtered in Europe each year. Of the 125 million male pigs, approximately 20% are left entire, less than 3% are castrated with anaesthesia and the rest is castrated without anaesthesia. The study identified large variations in castration procedures, both within and between countries. In females, castration is very rare, but is practiced without anaesthesia in special breeds/production systems in some of the southern countries. [ABSTRACT FROM AUTHOR]

Stress neuroendocrine systems (hypothalamic?pituitary?adrenal axis and sympathetic nervous system) were studied in 100 female pigs from each of the five main genetic lines used in Europe for pork production: Pi?train, Large White, Landrace, Duroc and Meishan. Levels of cortisol and catecholamines were measured in urine collected at the farm, after transportation to the slaughterhouse and the next morning before slaughter. With the exception of the Pi?train line that showed intermediate levels of cortisol despite its extreme leanness, a significant positive relationship was found between basal cortisol levels and fatness, both across and within (except in Pi?train and Duroc) lines. Basal cortisol levels were 2.46-fold higher in Meishan (20.46 ng/mg creatinine) than in Large White pigs (8.30 ng/mg creatinine), the two extreme breeds. Post-transportation levels were highest but proportional to basal levels, suggesting that the adrenal reactivity to adrenocorticotropic hormone is a major source of variability between lines. Levels of catecholamines were less variable between lines but correlated also with fatness, partlyviapartial correlations with cortisol levels. In serum collected at exsanguination, creatine kinase activity was correlated with muscularity across the five breeds. However, this was due to a much larger activity than expected in Pi?train pigs, although all animals were negative for the allele of the ryanodine receptor gene responsible for stress sensitivity. Serum glucose levels were inversely related to fatness. These data show that the differences between breeds or lines can be utilised by cross-breeding and that this can lead to changes in stress hormones and in turn to some degree of changes in carcass traits.
