Assessing the Hygiene of Retail Refrigerated Pre-marinated Beef Steaks in Beijing via Flow Cytometry
摘要
Abstract
In order to assess the hygiene of retail refrigerated pre-marinated beef steaks rapidly and accurately,this study developed a colony count detection method based on flow cytometry.The T-test results showed no significant difference between the flow cytometry results and the national stan-dard method(p<0.05),and Pearson's correlation analysis demonstrated a significant relationship be-tween the two methods(p<0.001).This indicates that flow cytometry can be used to replace the GB 4789.2 national standard for analyzing colony counts in refrigerated pre-marinated beef steaks.Fur-ther,Chi-square analysis revealed no significant differences in hygiene among beef steaks sold in dif-ferent supermarkets,suggesting that temperature control at the retail level is not the main factor af-fecting beef steak hygiene.Further metagenomic tracing confirmed that the hygiene of beef steaks is closely related to the hygiene control of the production environment.关键词
