A Salinas, Calif., company is recalling romaine lettuce because it may be contaminated with salmonella.
Tanimura & Antle Inc. issued the recall after a random test conducted by the Wisconsin Department of Agriculture tested positive for salmonella.
Salmonella infections can be fatal to the young and the elderly. The organism can cause fever, diarrhea, nausea, vomiting and abdominal pain.
The company has instructed stores in 29 states, including California, to destroy the lettuce. The romaine also was sold to wholesalers and food-service providers.
