Abstract:
Objective:To understand the microbial contamination of student lunch in Huzhou, in order to provide reference for foodborne disease prevention and control.
Methods:In 2021, 225 samples of student lunch were randomly collected from 77 schools and detected for E.coli, S.aureus, B.cereus, Salmonella, Campylobacter, Listeria monocytogenes, and Diarrhoeal E.coli. According to the relevant standards, the status of microbial contamination was evaluated.
Results:The total unqualified rate was 2.67 %(6/225). The unqualified rates of E coli (>100 CFU/g) was 1.33%. The detection rates of B.cereus, S.aureus, Listeria monocytogenes, and diarrhoeal E.coli were 7.11%(16/225), 1.33%(3/225), 0.89%(2/225) and 0.44%(1/225), respectively. The unqualified rates of S.aureus (≥10 4 CFU/g) and B.cereus (≥10 5 CFU/g) were zero. There are statistical differences in the unqualified rate of student lunch among different school types( P <0.05). The unqualified samples mainly came from the primary school canteen, and the unqualified rate was 5.63%(4/71).
Conclusion:The sanitary quality of student lunch in Huzhou is acceptable, but there are different degrees of foodborne pathogens pollution, especially in primary schools, and supervision and management should be strengthened.
