Some Calif. lettuce may contain salmonella

State health officials warned consumers today not to eat certain Fresh Choice red leaf lettuce sold at three Southern California grocers, due to possible Salmonella contamination.

The lettuce was sold between Oct. 20 and Nov. 1 at Canton Food Co. in Los Angeles, Cardenas Market and Numero Uno Market locations throughout
Southern California, according to California Department of Public Health director Dr. Mark Horton.

Fresh Choice Marketing of Oxnard produced the lettuce and made it available in grocery stores as whole head lettuce without identifying labels, Horton said.
