Romaine Lettuce Caused Canada E. coli Outbreak
summary：An E. coli O157:H7 outbreak in New Brunswick, Canada that sickened at least 18 people in April has been linked to romaine lettuce, health officials announced Friday....
Ill persons ate at Jungle Jim's Eatery in Miramichi between April 23 and 26. The lettuce was served in salads, wraps and hamburgers.
According to CBC News, the outbreak strain also matched to cases of E. coli in Quebec and California.
Health officials said the contaminated lettuce has expired and does not pose any additional health risk.
Officials determined the lettuce as the likely source after interviewing 55 individuals -- 18 sickened and 37 control cases. Those sickened were much more likely to have eaten lettuce during the outbreak window.
