ObjectiveTo understand the contamination status and characteristics of major foodborne pathogens in meat and meat products sold in Zibo City， and provide scientific basis for preventing foodborne diseases and improving food safety supervision.MethodsAccording to the requirements of the National Food Contamination and Hazardous Factors Risk Monitoring Manual，the Shandong Province Food Contaminant and Harmful Factor Risk Monitoring Work Manual and the national standard method of food safety， 716 samples of 5 types of meat and meat products collected from 2015 to 2024 were isolated and identified for 8 foodborne pathogenic bacteria， including Salmonella， Listeria monocytogenes， Staphylococcus aureus， and Campylobacter. The isolated Salmonella was serotyped.ResultsA total of 245 pathogenic bacteria were detected in 716 samples， with Salmonella being the most detected （42.86%，105/245），with a total of 34 serotypes identified， the top three serotypes were Salmonella Enteritidis （17.14%，18/105）， Salmonella Indiana （9.52%， 10/105）， and Salmonella Derby （6.67%， 7/105）；followed by Listeria monocytogenes （14.29%，35/245） and Yersinia enterocolitica （12.24%，30/245）.The detection rate of raw poultry meat is the highest among different types of meat and meat products （46.64%，104/223）， followed by processed meat products （33.93%，19/56） and raw animal meat （24.91%，72/289）.ConclusionThere are varying degrees of contamination of foodborne pathogens in meat and meat products in Zibo City， with raw poultry being the most severely contaminated and mainly contaminated with Salmonella.
