Abstract As pork and pork products represent an important part of the diet, the issue of pork safety and quality has become more prominent. Food safety concerns are shaping consumers’ attitudes toward safe food. The farm and meat sectors aim at producing healthy animals in a protected environment, which is a key point for food/meat safety. The most common biological hazards in the pork production chain are Salmonella spp., Yersinia enterocolitica, Trichinella spp. and Toxoplasma gondii. These hazards are not detectable by conventional meat inspection, and measures rely on prevention or reduction of contamination along the production chain.

Abstract Infection with the apicomplexan protozoon Toxoplasma gondii is one of the most prevalent parasitic zoonotic infections globally, with existing seroprevalences varying between continents, countries, and even within countries and between individual communities. It is estimated that one third of the world’s human population is infected with T. gondii, with many studies showing that the dominant mode of infection is consumption of undercooked meat harbouring T. gondii tissue cysts. Prevalences of infection in food animals in different countries range from 0 to 93%. Because of the absence of clinical symptoms in infected animals, and the unfeasibility of rapid and unequivocal detection of microscopic tissue cysts in pork, infected pigs remain unrecognized, and their meat becomes an essential source of infection for humans. The data on T. gondii infection in pigs in Serbia from several studies, as well as on the detection of the parasite in different food categories, from fresh pork to heat-treated products, are discussed.

The implementation of the traditional meat safety control system has significantly contributed to increasing food safety and public health protection. However, several biological hazards have emerged in meat production, requiring a comprehensive approach to their control, as traditional methods of meat inspection at the slaughterhouse are not able to detect them. While national control programs exist for the most important meat-related hazards, similar data are still lacking for certain neglected threats, such as Yersinia enterocolitica or Toxoplasma gondii. The obstacle in controlling these hazards in the meat chain is their presence in latently infected, asymptomatic animals. Their effective control can only be achieved through systematic preventive measures, surveillance or monitoring, and antimicrobial interventions on farms and in slaughterhouses. To establish such a system, it is important to collect all relevant data on hazard-related epidemiological indicators from the meat chain, which should provide relevant guidance for interventions at the harvest and post-harvest stage. The proposed approach is expected to improve the existing system and provide many opportunities to improve food safety and public health.

Toxoplasma Gondii Infection

Toxoplasma gondii infection is widespread worldwide, not only posing a serious threat to human food safety and animal husbandry, but also endangering human health. The selectivity index was employed to measure anti-T. gondii activity. Hederagenin (HE) exhibited potent anti-T. gondii activity and low cytotoxicity. For this reason, HE was selected for in vivo experiments. HE showed 64.8%±13.1% inhibition for peritoneal tachyzoites in mice, higher than spiramycin 56.8%±6.0%. Biochemical parameters such as alanine aminotransferase, aspartate aminotransferase, glutathione, and malondialdehyde, illustrated that HE was a good inhibitor of T. gondii in vivo. This compound was also effective in relieving T. gondii-induced liver damage. Collectively, it was demonstrated that HE had potential as an anti-T. gondii agent.

Yersinia enterocolitica, kao i druge bakterije iz familijeEnterobacteriaceae, ima sposobnost opstanka u spoljašnjoj sredini, u koju dospevapreko inficiranih životinja. U Evropi, svinje su najčešći asimptomatski nosiocipatogenih sojeva Y. enterocolitica za ljude, posebno soja biotipa 4 (serotipa O:3) i netako učestalog biotipa 2 (serotip O:9 i O:27). Uzročnici su najčešće lokalizovani uoralnoj duplji, posebno u tonzilama, submaksilarnim limfnim čvorovima, crevima ifecesu svinja. Pravilan postupak sa trupovima svinja, nakon klanja, može znatno dasmanji nivo kontaminacije mesa svinja. Učestalost Y. enterocolitica kod svinja, kaorezervoara ovog patogena, veoma varira. Slučajevi jersinioze kod ljudi zabeleženi su,kako u Evropi, tako i u Japanu, SAD, Nigeriji i Brazilu.

Abstract Background The parasite Toxoplasma gondii (T. gondii) is recognized as one of the major foodborne pathogens with a high human disease burden. To control T. gondii infections in pigs, European Food Safety Agency (EFSA) advises serological testing of pigs and audits of pig farms to identify risk factors for T. gondii infection. In line with this approach, the aim of the current study was to assess the effectiveness and costs of intervention measures implemented to reduce the T. gondii seroprevalence on finishing pig farms in the Netherlands. A crossover clinical trial was conducted at five case farms were their own control and the cross-over moment was the implementation of interventions to reduce risk factors. Each of the case farms had a farm-specific intervention strategy with one principal intervention measure (neutering of cats, professional rodent control or covering food storage). Results All finishing pig farms (n = 5) showed a reduction in T. gondii seroprevalence within one year of implementing the intervention strategy. Cat neutering (n = 3) and feed coverage (n = 1) showed statistically significant reductions in seroprevalence. Rodent control (n = 1) did not show a statistically significant reduction. The estimated reduction in seroprevalence in response to the neutering of cats and feed coverage were 67 and 96 %, respectively. Conclusions Our work demonstrates that it is possible to reduce the within-farm T. gondii seroprevalence within one year after interventions were implemented to reduce T. gondii risk factors. This information is essential and encouraging for policy makers, food business operators, and farmers to implement in their risk assessment and to apply to food safety control systems.
