An E. coli outbreak has led to the recall of a common grocery deli food in four states.

UPDATE: The Centers for Disease Control reports that 19 people have become ill from E. coli contamination in seven states. The illnesses are believed to be linked to Costco rotisserie chicken salad. Five people have been hospitalized, but no deaths have been reported. Affected states now include Colorado, Montana, Washington, Utah, California, Missouri and Virginia. The CDC, USDA and U.S. Food and Drug Administration are working with Costco to identify the ingredient that caused the outbreak.

Following four reported illnesses in Colorado, Costco is recalling its "Chicken salad made with rotisserie chicken" (item number 37719) in Colorado, Utah, Montana and Washington. One person was hospitalized, and all have recovered. They bought the chicken salad on Oct. 25 and 26, and they became ill between Oct. 28 and Nov. 3.

Meanwhile, other cases of E. coli-related illnesses have been linked to the chicken salad in Utah, Montana and Washington.

Chicken salad can fly under the radar as a source of contamination because the chicken is usually fully cooked. But there is the mayonnaise — not a typical cause of E. coli contamination, but it can happen, even with commercially made mayo. In this case, officials are still investigating the source of the contamination, so we don't know whether it's the chicken, the dressing or any vegetable or garnishes added.
