Monitoring results of food microbial contamination in Luoyang of Henan,2018-2023
Objective To understand the status of food microbial contamination in Luoyang city so as to provide scientific evidence for the risk monitoring and supervision of food safety.Methods A total of 13 types of food samples were collected in Luoyang City from 2018 to 2023.According to the General Rules for Microbiologic Test of Food Hygiene(GB/T 4789.1-2016),the detection results of five hygienic indicator bacteria and ten pathogenic bacteria were analyzed.Results Of the 1 127 food samples collected in Luoyang from 2018 to 2023,the over-standard rate of hygienic indicator bacteria was 29.88％(205/686);the detection rate of pathogenic bacteria was 17.73％(191/1 077),and Bacillus cereus had the highest detection rate,which was 33.68％(65/193).The unqualified rate of samples was 28.57％(322/1 127).There were statistically significant differences in the over-standard rates of hygienic indicator bacteria,the detection rates of pathogenic bacteria and the unqualified rates of samples in different years(x2 values were 109.828,64.107 and 82.660,respectively;all P＜0.05).The unqualified rate of samples showed a downward trend(x2trend=31.109;P＜0.05).In different food types,the over-standard rate of hygienic indicator bacteria and unqualified rate of samples for frozen drinks were highest,which both were 93.75％(30/32);the detection rate of pathogenic bacteria for aquatic products was the highest,which was 50.00％(6/12).In different sampling links,the over-standard rate of hygienic indicator bacteria,detection rate of pathogenic bacteria and unqualified rate of samples for the catering service link were highest,which were 40.31％(77/191),26.89％(64/238)and 40.34％(96/238),respectively.In different sampling sites,the over-standard rate of health indicator bacteria was highest in snack bar samples,which was 69.23％(27/39),and the detection rate of pathogenic bacteria and unqualified rate were highest for street stall samples,which were 50％(23/46)and 58.70％(27/46),respectively.Conclusions There were different degrees of microbial contamination in various food and sampling links in Luoyang city.Relevant departments should further strengthen food safety monitoring and supervision to ensure food safety of residents.
