Consumers who have any type of romaine lettuce in their home are urged to throw it out immediately, even if some was eaten and no one has gotten sick.
The outbreak involves a strain of the bacteria called Shiga toxin-producing E. coli O157:H7, which may cause serious illness. Thirteen of those people were hospitalized, including one who suffered kidney failure.
The CDC will be providing new updates as it learns more about this particular outbreak, but until then, just avoid the leafy vegetable and you should be okay.
There is another E. coli outbreak in the U.S., and the agency has traced it back - yet again - to the usual suspect: the crunchy and leafy green served across the country.
Additionally, you should make sure to wash and sanitize drawers or shelves in refrigerators where romaine was stored.
The Food and Drug Administration says it's working with officials in Canada, where people are also being warned to stay away from romaine lettuce.More news: China, Others Woo Pacific With A Boulevard, A Bible And A Barbecue
Restaurants and retailers should not serve or sell any romaine lettuce, including salads and salad mixes containing romaine.
CDC is advising that consumers do not eat any romaine lettuce because no common grower, supplier, distributor, or brand of romaine lettuce has been identified.
Write down what you ate in the week before you started to get sick.
The illnesses range from October 8 - Oct. 31.
This strain - E. coli O157:H7 - is the same as the one which caused an outbreak a year ago from romaine and unspecified leafy greens grown in Canada.
Symptoms of E. coli infection, which typically begin three to four days after the bacteria is ingested, include severe stomach cramps, diarrhea and vomiting.
