WATCH E. Coli Outbreak Linked to Costco Chicken Salad

An E.coli outbreak that has sickened 19 people in seven states was linked to rotisserie chicken salad from Costco, according to the Centers for Disease Control and Prevention.

The report from the CDC -- which says people fell ill between Oct. 6 and Nov. 3 -- says five of those who have become ill have been hospitalized. Two people have developed a type of kidney failure associated with E.coli infection, the CDC said.

Although the investigation is ongoing, 14 people purchased or ate rotisserie chicken salad from Costco in the week before illness started, according to the CDC.

The CDC also said that it is not yet known which specific ingredient in the chicken salad is linked to the illnesses.

Consumers are advised to throw out any rotisserie chicken salad purchased before Nov. 20 bearing the label "Chicken Salad made with Rotisserie Chicken" with item number 37719, according to the CDC.

Costco did not immediately return request for comment.
