WASHINGTON • Health officials in the United States have warned consumers not to eat any romaine lettuce and to throw away any they might have in their homes, citing an outbreak of E. coli poisoning.
The Centres for Disease Control and Prevention (CDC) issued the warning on Tuesday against all romaine lettuce just two days before the Thanksgiving holiday, when American families gather and feast together.
"Consumers who have any type of romaine lettuce in their home should not eat it and should throw it away, even if some of it was eaten and no one has become sick," the CDC said, after 32 people were reported sick from E. coli poisoning in 11 states, with 13 of them hospitalised.
One of those had suffered kidney failure.
Health officials in Canada said they had also identified 18 people stricken with the same strain of food poisoning in two provinces, Ontario and Quebec.
"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," the CDC said, noting that it had not been able to pinpoint precisely where the suspect leaves had originated.
"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," the CDC said.
It advised anyone who had stored romaine lettuce in the refrigerator to wash down the shelves where the leaves had been kept.
No deaths have so far been reported.
