Consumer Reports is advising people against eating any Wendy's sandwich or salad with romaine lettuce until more is known about a strain of E. coli that has sickened 37 people, hospitalizing 10.
The non-profit advocacy group cited its food safety experts in urging a cautious approach until the fast-food chain can confirm the source of the pathogen and details how it plans to address the problem.
"E. coli can be especially harmful to young children, infants, older persons and those with a compromised immune system," James Rogers, CR's director of food safety and testing, said Monday in a statement. "The goal is to minimize your risk of getting it, and until we know more about its source, it's safest to avoid consuming Wendy's sandwiches served with lettuce and any Wendy's salad containing romaine lettuce."
While the source of the outbreak is unclear, many of the 37 people who recently contracted E. coli reported eating lettuce at a Wendy's location in Michigan, Ohio or Pennsylvania before getting sick, the Centers for Disease Control and Prevention said on Friday.
"Romaine lettuce served on burgers and sandwiches at Wendy's was one of the most common ingredients eaten among the menu items, but investigators continue to analyze data at the ingredient level to determine if there are any other possible foods that could be the source of the outbreak," the agency said.
Larger outbreak?Fifteen of those who fell ill live in Michigan, 19 are from Ohio, two are from Pennsylvania and one is from Indiana, according to the CDC. Of the 26 of those who were interviewed as part of an agency probe, 22 said they ate at a Wendy's in the week before they got sick.
But the actual number of those sickened in the outbreak is likely higher than reported and could include more than four states, the CDC noted.
Reached for comment, a Wendy's representative said the company is cooperating with public health officials investigating the outbreak. The company also has discarded and replaced the sandwich lettuce at some eateries in the region where people were stricken.
"The lettuce that we use in our salads is different, and is not affected by this action," Wendy's said.
Romaine lettuce and other greens like spinach and clover sprouts have been involved in at least 17 E. coli outbreaks around the U.S. between 2006 and 2019, according to the CDC.
Dublin, Ohio-based Wendy's and its franchisees operate about 7,000 restaurants worldwide.
