Romaine lettuce E. coli outbreak: Mass., N.H. among affected states
NEW YORK — Health officials in the US and Canada told people on Tuesday to stop eating romaine lettuce because of a new E. coli outbreak.
The US Food and Drug Administration said it is working with officials in Canada on the outbreak, which has sickened 32 people in 11 states and 18 people in the Canadian provinces of Ontario and Quebec.
The strain identified is different than the one linked to romaine earlier this year but appears similar to last year’s outbreak linked to leafy greens.
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 until the source of the contamination can be identified.
The contaminated lettuce is likely still on the market, Gottlieb told The Associated Press in a phone interview Tuesday.
He said FDA wanted to issue a warning before people gathered for Thanksgiving meals, where the potential for exposure could increase.
‘‘We did feel some pressure to draw conclusions as quickly as we could,’’ he said.
Most romaine sold this time of year is grown in California, Gottlieb said. The romaine lettuce linked to the E. coli outbreak earlier this year was from Yuma, Arizona. That outbreak, which sickened about 200 people and killed five, was blamed on tainted irrigation water.
No deaths have been reported in the current outbreak, but 13 people in the US and six in Canada have been hospitalized. The last reported US illness was on Oct. 31, while and the most recent illness in Canada was early this month.
Tracing the source of contaminated lettuce can be difficult because it’s often repackaged by middlemen, said Sarah Sorscher, deputy director of regulatory affairs at the Center for Science in the Public Interest. That can mean the entire industry becomes implicated in outbreaks, even if not all products are contaminated.
‘‘One of the problems with produce is that it can be very hard to trace back,’’ she said.
She said washing contaminated lettuce won’t ensure that harmful germs are killed.
Infections from E. coli can cause symptoms including severe stomach cramps, diarrhea and vomiting. Most people recover within a week, but some illnesses can last longer and be more severe.
Health officials have also been reminding people to properly handle and cook their Thanksgiving birds amid a widespread salmonella outbreak linked to raw turkey. Last week, Hormel recalled some packages of Jennie-O ground turkey that regulators were able to tie to an illness.
But unlike with romaine lettuce, regulators are not warning people to avoid turkey. Salmonella is not prohibited in raw meat and poultry, and the US Department of Agriculture, which overseas raw meat, said cooking should kill any salmonella.
According to a map released by the CDC, states that have seen people infected in the outbreak include Massachusetts, New Hampshire, Connecticut, New York, New Jersey, Maryland, Ohio, Michigan, Wisconsin, Illinois, and California.
California and Michigan had the most amount of people affected, at 10 and 7, respectively.
The following is the information provided by the CDC on Tuesday:
Advice to Consumers, Restaurants, and Retailers:
CDC is advising that US consumers not eat any romaine lettuce, and retailers and restaurants not serve or sell any, until we learn more about the outbreak. This investigation is ongoing and the advice will be updated as more information is available.
• This advice includes all types or uses of romaine lettuce, such as whole heads of romaine, hearts of romaine, and bags and boxes of precut lettuce and salad mixes that contain romaine, including baby romaine, spring mix, and Caesar salad.
• If you do not know if the lettuce is romaine or whether a salad mix contains romaine, do not eat it and throw it away.
• Wash and sanitize drawers or shelves in refrigerators where romaine was stored. Follow these five steps to clean your refrigerator.
• Restaurants and retailers should not serve or sell any romaine lettuce, including salads and salad mixes containing romaine.
