Between Oct. 30 and Dec. 10, 1971, there were a hundred and seven episodes of gastroenteritis involving at least 387 persons in the U.S.A. traced to imported French cheese. Enteropathogenic Escherichia coli O 124:B17 was identified in both stool and cheese specimens. Diarrhœa, fever, and nausea were the most common symptoms. Cramps, chills, vomiting, aches, and headaches were less common. The median time before onset of symptoms was eighteen hours after ingestion of the contaminated cheese; and the median duration of the illness was two days. Laboratory tests indicated that the E. coli O 124 was invasive but not enterotoxigenic. This is believed to be the first adequately documented occurrence of enteropathogenic E. coli foodborne disease in the U.S.A. |
