Fresh Express Recalling Romaine Salad Lettuce

A possible contamination threat is prompting the "Fresh Express" company to recall some bags of romaine salad lettuce.

There are concerns of possible E. Coli contamination.

The company and the U.S. Food and Drug Administration say the voluntary recall involves fresh express romaine salads with expired "use-by'' dates of July 8 - 12 and an "S'' in the product code.

FDA says the recall comes after one package of the salad test positive for E. Coli.

No illnesses have been reported.
