Recent Studies from University of Zagreb Add New Data to Yersinia enterocolitica (Relevance of Meat Juice Seroprevalence and Presence of * * Yersinia enterocolitica* * and * * Salmonella* * spp. in Pig Tonsils for Risk Management at Slaughter): Foodborne Diseases and Conditions – Yersinia enterocolitica

2023 SEP 13 (NewsRx) -- By a News Reporter-Staff News Editor at Insurance Daily News -- New study results on Yersinia enterocolitica have been published. According to news originating from Zagreb, Croatia, by NewsRx correspondents, research stated, “* * Salmonella* * spp. and * * Yersinia enterocolitica* * are priority bacteriological public health hazards in pork safety.”

Funders for this research include European Social Fund And The Operational Program Effective Human Resources.

Our news reporters obtained a quote from the research from University of Zagreb: “For more successful control, it is necessary to collect data on their prevalence throughout the meat chain using the concept of harmonized epidemiological indicators. The aim of this study was to determine their prevalence in fattening pigs under different housing conditions by recovering the pathogen from tonsils and by serological testing of diaphragm meat juice at slaughterhouses. The overall prevalence of * * Salmonella* * spp. and * * Y. enterocolitica* * in tonsils was 9.8% and 6.5%, respectively, with no significant differences between large and small farms (* * p* * > 0.05). In general, seroprevalence of * * Salmonella* * spp. was 48.35% and of * * Yersinia* * 13.18% (* * p* * < 0.05) but without significant differences of individual seroprevalence between farm types. No association was found between detection of * * Salmonella* * spp. or * * Y. enterocolitica* * in tonsils and seroprevalence (phc = 0.121, * * p* * = 0.420; phc = 0.027, * * p* * = 0.718, respectively). Significantly higher seroprevalence of * * Salmonella* * spp. was found on farms with lower biosecurity status (* * p* * < 0.05).”

According to the news editors, the research concluded: “A higher recovery rate of * * Salmonella* * spp. and * * Y. enterocolitica* * from the tonsils may be expected in seropositive pigs (OR 1.56-2.36), but without statistical significance. The results showed that * * Salmonella* * and * * Yersinia* * meat juice serology can be considered for risk categorization of pig farms as a less-time consuming and more sensitive method compared to microbiological testing of tonsils but must be combined with analyses of other risk factors relevant to infection or contamination in the pork chain.”
