Consumer Reports food safety experts said Friday that people should avoid all romaine lettuce and that any currently in refrigerators should immediately be thrown out because of the risk of E. coli contamination.
The Food and Drug Administration announced Friday that romaine lettuce grown in Salinas, Calif., is likely responsible for a multistate E. coli O157:H7 outbreak that was first reported earlier this week.
On Friday, the Centers for Disease Control and Prevention said the number of illnesses had risen to 40 people in 16 states. Of those reported infected, 28 have been hospitalized but there were no reported deaths. The states involved are Arizona, California, Colorado, Idaho, Illinois, Maryland, Michigan, Minnesota, Montana, New Jersey, New Mexico, Ohio, Pennsylvania, Virginia, Washington, and Wisconsin.
Yesterday, Missa Bay recalled 97,272 pounds of packaged salad kits and bowls it shipped to 22 states. The romaine lettuce in those salads was grown in Salinas.
The FDA is currently advising consumers to avoid lettuce grown in Salinas and directing them to read the labels on the lettuce they buy. According to the FDA, lettuce grown in other areas does not appear to be linked to the current outbreak. Hydroponic or greenhouse lettuce also does not seem to be involved.
But CR’s experts think it is prudent and less confusing for consumers to avoid romaine altogether, especially because romaine is also sold unpackaged and in restaurants, and customers can’t always be sure of the origin that lettuce.
“Much of the romaine lettuce on the market at this time of year is from Salinas,” says James E. Rogers, Ph.D., director of food safety research and testing at Consumer Reports. “Last year, also right before Thanksgiving, there was an E. coli O157:H7 outbreak, and the FDA and the CDC warned people against eating any romaine lettuce and called on stores and restaurants to stop selling it.”
The FDA is also asking the leafy green industry to voluntarily stop shipping Salinas romaine for the rest of the growing season. A spokesperson for the California Leafy Greens Marketing Agreement told CR that the growing season is almost over, with production shifting to California’s Imperial Valley and Central Coast, and to Yuma, Ariz.
How Can You Tell Where Romaine Was Grown?
After romaine was involved in two E. coli outbreaks in 2018—one in November and one in the spring (which involved lettuce grown in Yuma)—the FDA worked with the leafy greens industry to create a voluntary labeling program that would help consumers know the origin of the romaine lettuce they were buying. The information would be found on tags on the lettuce, on packaging, or on signs at the point of purchase.
“We have seen a lot of growers provide the harvesting location of their romaine,” says Peter Cassell, spokesperson for the FDA. “If the lettuce was produced in Salinas, consumers should avoid it. And if you can’t confirm that romaine lettuce isn’t from Salinas, consumers should avoid it.”
When the growing area labels were first introduced, CR food safety experts found that as a warning system for consumers to protect themselves in real time, the program had flaws, and that stronger measures would be needed to keep consumers safe. The system is unrealistic, Rogers says, because it relies on shoppers knowing there has been an outbreak, remembering its origin, and also knowing to look for label.
The LGMA spokesperson said that the organization believes that Salinas growers will follow the FDA’s request to stop shipping romaine. But Rogers points out that there is no way to enforce it.
Even so, Rogers says it is safer in the midst of a rapidly changing outbreak to simply forgo all raw romaine for now, especially for people who are vulnerable to food poisoning and its effects, meaning the elderly, the very young, and pregnant women.
“If the package is clearly marked with the growing area and it is not Salinas, or you can find hydroponic or greenhouse-grown romaine—which wouldn’t be affected—that’s fine,” Rogers says. “But we think that consumers will not find it so easy to make that determination, and we would rather see them play it safe and choose other types of lettuce right now.”
