The CDC says “Stop eating romaine lettuce”. Health officials in the U.S. and Canada on Tuesday told people to avoid eating romaine lettuce because of a new E. coli outbreak. The U.S. Food and Drug Administration said it was working with officials in Canada on the outbreak, which has sickened 32 people in 11 states in the U.S. and 18 people in the Canadian provinces of Ontario and Quebec. Michigan has the second-highest number of cases at seven. Simply washing the lettuce will not ensure that contaminated lettuce is safe.

FDA Commissioner Scott Gottlieb said the agency doesn't have enough information to ask suppliers for a recall, but he suggested that supermarkets and restaurants should withdraw romaine lettuce from store shelves until the source of the contamination can be identified. People are also being advised to throw out any romaine they have at home.

The contaminated lettuce is likely still on the market.
