Abstract

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.

Summary

Biological Hazards in the Meat Chain

Bacterial intestinal pathogens have always been a challenge in meat hygiene, such as Salmonella spp., Yersinia spp., Campylobacter spp., Listeria monocytogenes, or Escherichia coli [1] They are not physiologically present in the meat but get there during the slaughter processing of the animals, and in the further course of handling and processing of meat by equipment, surfaces, and personnel [11,12]. The number of EU countries reporting the results of their on-farm bacterial surveillance programs is inconsistent and varies considerably across species This is true at the slaughter stage, where data are most complete only for Salmonella in pigs, and there. 6% in domestic pigs (CI 95%: 3–10%), 23% in sheep (CI 95%: 12–36%), 7% in cattle (CI 95%: 1–21%), 33% in wild boars (CI 95%: 26–41%), and 16% in moose (CI 95%: 10–23%)
