SALINAS, Calif. A California farm said Thursday it was voluntarily recalling bags of chopped romaine lettuce because of possible contamination with listeria, though no illnesses have been reported.
True Leaf Farms of Salinas announced the recall of 90 cartons that were shipped to an Oregon food service distributor. From the distributor, it might have gone to at least two other states, Washington and Idaho.
The Food and Drug Administration notified the company that a sample from one bag taken as part of a random check tested positive for listeria.
Federal health officials say they've gotten better at detecting the germs that cause food poisoning, so they are seeing them in produce more often.
The recall covers product with a use by date of Sept. 29. The bag and box code is B256-46438-8.
