上周在阿姆斯特朗举行的西北欧微生物组会议上,讨论了控制食品和水中微生物污染问题,特别注意大肠杆菌和其他肠道细菌。大肠杆菌的存在长久以来被看作粪便污染的指标,虽然它们本身不致病。但是大肠杆菌的毒株已开始发现。瑞典一家实验室偶然发现106人吃了带大肠杆菌的色拉后,有60人发生剧 Last week at the Northwestern European Microbial Conference in Armstrong, the issue of controlling microbial contamination of food and water was discussed, with particular attention to E. coli and other gut bacteria.
