Costco: FDA Tests Indicate Vegetables in Chicken Salad May Be E. Coli Source

Initial testing by the U.S. Food and Drug Administration (FDA) points toward a vegetable mix sourced from a California produce wholesaler as the potential source of E. coli connected with Costco’s rotisserie chicken salad.
