Costco: FDA Tests Point Toward E. Coli In Salad Vegetables

Costco officials say testing has pointed toward a vegetable mix from a California food wholesaler as the source of E. coli in the company’s chicken salad that has been linked to an outbreak that has sickened 19 people in seven states. Craig Wilson, Costco vice president of food safety and quality assurance, said Wednesday he was told by the Food and Drug Administration that the strain of E. coli seems to be connected to an onion and celery mix.
