A report by the Centers for Disease Control and Prevention said federal and state public health officials are interviewing ill persons to obtain information regarding foods they might have eaten and other exposures in the week before their illness.
Testing conducted by the New York State Department of Health's Wadsworth Center Laboratory in Albany, N.Y., identified the outbreak strain of STEC O121 in an open package of Farm Rich brand frozen chicken quesadillas from an ill person's home.
The U.S. Department of Agriculture Food Safety and Inspection Service and the U.S. Food and Drug Administration are also currently conducting investigations to determine the source of infections in this outbreak, the CDC said.
The CDC said 78 percent of ill the persons were age 21 or younger and 33 percent of ill persons were hospitalized. One ill person developed hemolytic uremic syndrome, a type of kidney failure, but no deaths were reported, the CDC said.
Rich Products Corp., in Buffalo, N.Y., the parent company of Farm Rich issued a voluntary recall last Thursday of approximately 196,222 pounds of Farm Rich brand frozen chicken quesadillas and several other frozen mini meals and snack items because they might be contaminated with E. coli O121.
