(NEW YORK) -- An E. coli outbreak caused by Costco's chicken salad has now been linked to specific ingredients within the salad.
According to the Centers for Disease Control and Prevention, a sample of celery and onion was taken from a Costco store that was used to make the rotisserie chicken salad and results from the Montana Public Health Laboratory revealed the prsence of E. coli.
The CDC said laboratory testing was still ongoing.
Because of the lab results, Taylor Farms Pacific Inc. has recalled many of its products that contain celery due to the E. coli concern.
Earlier this week, 19 people were reported to be infected by the outbreak, according to the CDC. Five people were hospitalized, two developed a type of kidney failure called hemolytic uremic syndrome, and most of the reported illnesses came from the western United States, said the CDC.
Consumers were 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.
