After linking a number of cases of E. coli poisoning back to chicken salad bought at Costco, the warehouse chain has pulled the product from its shelves in the western portion of the U.S.

Yesterday, Colorado health officials confirmed that the state had linked four local E. coli illnesses to Costco’s “Chicken Salad made with Rotisserie Chicken,” and that they knew of other related illnesses in Utah, Washington, and Montana.

Anyone with any of this chicken salad in their fridge is directed to throw it out, lest you want to risk the diarrhea, cramps, nausea, and vomiting associated with E. coli. Anyone who did eat this particular salad and feels ill is advised to see a physician.

One of the four Colorado cases resulted in hospitalization. Thankfully, all four have recovered.

Washington state officials have confirmed they are investigating and that they know of one case of E. coli poisoning related to the chicken salad.

FoodSafetyNews.com reports that Costco is working with the FDA, the USDA’s Food Safety and Inspection Service, and the Centers for Disease Control and Prevention to determine the source of this contamination.

This is the second E. coli outbreak tied to a major national brand this fall, as Chipotle deals with the fallout of making dozens of customers sick in at least six states.
