Analysis of Isolation Identification and Pathogenicity for Foodborne Pathogens in Animal Food in a City
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.
