Surveillance on poultry and livestock meat for Salmonella,Listeria monocytogenes and Campylobacter contamination in Inner Mongolia
Objective:To investigate the contamination situation of the Salmonella Spp,Listeria monocytogenes and Campylobacter Spp in raw poultry and livestock meat in Inner Mongolia,so as to provide basic information for the prevention and control food-borne diseases,and guidance for rele-vant supervisory departments.Methods:A total of 3171 samples of raw poultry and livestock meat were collected from 12 cities from 2016 to 2020.According to the National Standard for Food Safety (GB4789-2016,GB 4789-2014)and Manual for Food-borne Disease Surveillance,the pathogenic bacteria were monitored.Results:From 2016 to 2020,a total of 346 positive strains of pathogenic bac-teria were detected in 3171 samples,with a total detection rate of 10.91％(346/3171).The total de-tection rates of Salmonella,Listeria monocytogenes and Campylobacter were 8.56％(85/993 ), 5.62％(50/889)and 16.37％(21/1289),respectively.The pathogen contamination rate of bulk samples is higher than that of pre-packed samples.The detection rate of Listeria monocytogenes in fro-zen meat was the highest,17.53％(27/154).The detection rates of Salmonella were higher in online stores and convenience stores/retail stores (22.22％(4/18)and 14.57％(22/151),respectively. The highest detection rate of Campylobacter was 40.55％(103/254)in the breeding link,and no samples were detected in the slaughtering process.Conclusion:From 2016 to 2020 Campylobacter Spp contamination was the highest in raw poultry and livestock meat in Inner Mongolia,and Listeria mono-cytogenes was low.In order to reduce the incidence of foodborne diseases,it is necessary to strengthen the supervision and management of raw poultry and livestock meat in different segments,so as to en-sure the food safety and health of the people.
