ATLANTA -- Lettuce that is sold in Georgia is being recalled because of possible salmonella contamination.

Tanimura and Antle is voluntarily recalling approximately 22,000 cartons of romaine lettuce, because the lettuce may be contaminated with salmonella.

The company learned about a possible contamination on Monday and traced it back to an entire lot of greens.

So far, no sicknesses from the lettuce have been reported, health officials said.
