摘要
为了解某市动物性食品中食源性致病菌分布情况及致病性,在2022年8月至2023年3月对猪肉、牛肉、鸡肉、鸭肉4类动物性食品进行食源性致病菌分离鉴定分析工作,并以小白鼠为对象实施致病性分析。结果显示,牛肉致病菌检出率最高(6.25%),其次是鸭肉与猪肉(5.00%),最后为鸡肉(3.75%);检测的猪肉、鸡肉、鸭肉、牛肉中均存在沙门氏菌、金黄色葡萄球菌、单增李斯特菌;分离出的食源性致病菌致病性较强,其中沙门氏菌致病率为80.00%,金黄色葡萄球菌致病率为83.33%,单增李斯特菌致病率为75.00%。某市动物性食品中存在食源性致病菌感染情况,且致病性较强,相关部门需要重点加大监测力度,保证动物性食品安全。
In order to understand the distribution and pathogenicity of foodborne pathogens in animal food in a certain city,from August 2022 to March 2023,four types of animal food in a certain city,namely pork,beef,chicken,and duck,were isolated,identified,and analyzed for foodborne pathogens,and pathogenicity tests were conducted on mice.The results showed that the detection rate of beef was the highest(6.25%),followed by duck and pork(5.00%),and finally chicken(3.75%);Salmonella,Staphylococcus aureus,and Listeria monocytogenes are present in the detected pork,chicken,duck,and beef foods.The isolated foodborne pathogens have strong pathogenicity,with Salmonella having a pathogenicity rate of 80.00%,Staphylococcus aureus having a pathogenicity rate of 83.33%,and Listeria monocytogenes having a pathogenicity rate of 75.00%.It has been found that there are foodborne pathogenic bacteria infected in animal food in a certain city,and the pathogenicity is strong.Relevant departments need to focus on increasing monitoring efforts to ensure the safety of animal food.
