主 题：Diarrheal syndrome food poisoning ready-to-eat vegetable greenhouse microbial risk assessment
摘 要：Objectives:Bacillus cereus isolates from vegetables can cause diarrheal syndrome food ***,the most highly consumed readyto-eat vegetable,poses a signifcant risk of *** ***,*** monitoring and evaluation during cultivation are essential for preventing foodborne illnesses caused by this food-pathogen ***,the impact of different cultivation practices on *** contamination in lettuce currently remains ***,a validity indicator for the experimental models cannot be effectively validated under feld *** and Methods:Herein,we assessed the risk of *** exposure using lettuce grown under two different cultivation farming systems in China(open-feld versus greenhouse)using a quantitative microbial risk assessment ***’s mean comparison method and kernel density estimation frequency distribution statistics were used for model validation using environmental samples and ***:The mean concentration of *** in open-feld-grown lettuce was signifcantly higher than that in greenhouse-grown lettuce(P0.05),verifying the accuracy of the risk ***:Soil solarization,complete manure treatment,usage of mulch flms,and irrigation water quality should be considered in agricultural practices to control *** concentrations in ***,we found that *** was more abundant in open-feld-grown lettuce,and we provide a risk evaluation framework that can guide farmers and policy-makers to control *** contamination in farm-to-fork lettuce chains in China.
