肉鸡屠宰加工过程中沙门菌污染定量风险评估
Quantitative Risk Assessment on Salmonella Contamination during Slaughtering and Processing of Broiler Chickens
摘要
Abstract
In order to establish a quantitative risk assessment model of Salmonella contamination during slaughtering and processing of broiler chickens,analyze the dynamic changes of Salmonella,and to identify the key risk points,the surveillance and survey data of Salmonella contamination from chicken slaughterhouses in 2015 were adopted,then a risk assessment model was established,in which the defeathering was taken as the start point,and it includedmodular processes of eviscerating,cleaning and precooling,splitting and transmission. At last,using differentdistributions to describe variables,the assessment model was conducted simulation run by software @RISK software.The results showed that,by the established model,the Salmonella contamination level in terminal chicken products after slaughtering and processing was between 0~9 MPN(90% confidence interval). Meanwhile,based on the actual monitoring data,the contamination level was calculated as 5.3 MPN,demonstrating the assessment model was credible. According to the simulation data of every link,the dynamic changes of Salmonella in chickens were analyzed,and it was found that Salmonella decreased obviously after precooling,but it increased again after splitting and transmission. By analysis of fitting correlation coefficient,the Salmonella in the conveyer belts was clarified as the key risk point to influence the Salmonella contamination in the terminal products. The established quantitative risk assessment model would provide theoretical basis for Salmonella supervision and risk management in poultry slaughterhouses.关键词
