In a tweet, the FDA warned consumers regarding packaged single heads of romaine lettuce. They are bagged under the brand Tanimura and Antle.
Consumers should not eat the lettuce, the FDA added. It is believed they were distributed in many states including California.
The lettuce brand announced it would voluntarily recall the items. Items falling under this warning are labeled with package dates of 10-15 and 10-16.
