At least 19 people may have been infected by E.coli after eating rotisserie chicken salad sold at Costco Wholesale Corp's stores, the U.S. Centers for Disease Control and Prevention said on Tuesday.

Five people have been hospitalized and two have developed a type of kidney failure, although no deaths have been reported, the Centers for Disease Control and Prevention said.

"The epidemiologic evidence available at this time suggests that rotisserie chicken salad made and sold in Costco Wholesale stores in several states is a likely source of this outbreak," the CDC said.

The majority of the infections were reported from the western United States.
