微生物检测技术在食品检验中的检测结果分析

Analysis of detection results of microbial detection technology in food inspection

目的分析微生物检测技术对食品检验结果的影响。方法选择2023年1月-2023年12月期间某检测机构内抽检的100份待检食品作为研究对象,均接受荧光聚合酶链式反应法(PCR)检查及传统国标法检测,观察记录微生物检测技术在食品检验结果。结果100份待检食品中包含水果52份、蔬菜34份以及肉类14份,抽检10份食物样本经荧光PCR法检出致病微生物以大肠杆菌4份最多,其次为金黄色葡萄球菌3份,第3为沙门氏菌2份,经传统国标法检出致病微生物以大肠杆菌4份最多,沙门氏菌、金黄色葡萄球菌均3份;3类共100份食品样本中,污染率最高者分别为生畜肉、生禽肉及水产品,共污染17份样本,检出致病菌以大肠杆菌、金黄色葡萄球菌、沙门氏菌居多。结论微生物检测技术能够检出食品中的致病微生物,分辨具体种类,应用价值良好。

Objective To analyze the impact of microbial detection technology on food inspection results.Method 100 samples of food to be tested from a testing institution between January 2023 and December 2023 were selected as the research subjects,all of which underwent fluorescence PCR and traditional national standard methods.The microbiological testing techniques were observed and recorded in the food inspection results.Result Among the 100 food samples to be tested,52 were fruits,34 were vegetables,and 14 were meat.Among the 10 food samples sampled,4 were Escherichia coli,followed by 3 Staphylococcus aureus and 2 were Salmonella.According to the traditional national standard method,4 were Escherichia coli,and 3 were Salmonella and Staphylococcus aureus;Among the 100 food samples from 3 categories,the highest contamination rates were found in raw animal meat,raw poultry meat,and aquatic products.A total of 17 samples were contaminated,and the most pathogenic bacteria detected were Escherichia coli,Staphylococcus aureus,and Salmonella.Conclusion Microbial detection technology can detect pathogenic microorganisms in food,distinguish specific types,and has good application value.
