Thirty-two people, including 13 who have been hospitalized, have been infected with the outbreak strain in 11 states, according to the CDC. That includes whole heads of romaine, hearts of romaine, and bags and boxes of pre-cut lettuce, as well as salad mixes that contain romaine.
No brand names have been identified and no recall was ordered.
Health officials in the USA and Canada told people on Tuesday to stop eating romaine lettuce because of a new E. coli outbreak. However, health officials believe the incident is related to illnesses reported in a previous E. coli outbreak from December 2017, which suggests there may be a reoccurring source of contamination. One person in CT was reported by the FDA to have been made sick.
"A traceback investigation" is underway to find the source of the romaine lettuce consumed by people who became ill", the agency said.
The FDA says retailers, restaurants, and other food service operators should not serve romaine lettuce until more is known about this outbreak. Wash and sanitize drawers or shelves in refrigerators where romaine lettuce has been stored and follow these five steps to clean your refrigerator.
Write down what you ate in the week before you started to get sick.
Assist public health investigators by answering questions about your illness. People have also become sick in California, Connecticut, Illinois, Maryland, Michigan, New Hampshire, New Jersey, New York, Ohio and Wisconsin.
Additionally, FDA and states are conducting laboratory analysis of romaine lettuce samples potentially linked to the outbreak. However, some strains can cause a range of symptoms including diarrhea, urinary tract infections, respiratory illness and pneumonia. Some people may develop a fever.
