Semi-quantitative risk assessment of Cronobacter sakazakii in lettuce in a district of Shanghai
摘要
Abstract
The contamination status of Cronobacter sakazakii(C.sakazakii)microorganisms in lettuce in a district of Shanghai was evaluated,according to the procedure of microbial risk assessment(MRA),using the semi-quantitative microbial risk assessment software Risk Ranger and sQMRA,along with residents'dietary consumption data.Based on our research conducted for this district of Shanghai,the probability of getting sick from eating lettuce contaminated with C.sakazakii for a healthy adult was 1.66×10-9 per day,and 7.63× 10-3 cases per year,with a risk coefficient of 9.More importantly,our analysis showed a very low probability of morbidity and death.Despite the low risk for C.sakazakii in ready-to-eat lettuce,the current risk management measures are still required to maintain this excellent status for lettuce.This study provided important data for risk assessment of pathogenic microorganisms in lettuce,which could be beneficial for quantitative risk assessment,as well as the prevention and control of foodborne diseases.关键词
