Consumers are being warned not to eat certain Del Rey tortilla products because they may cause illness.

Del Rey Tortilleria of Chicago initiated a recall in the U.S. after Illinois state officials determined that they were connected to outbreaks of illness in three Wisconsin schools.

All of the children experienced flu-like symptoms including vomiting, nausea and abdominal cramps. Microbial contamination is not suspected and U.S. officials are continuing their investigation to determine the cause of the illnesses.

While the products are available in Ontario, there have been no reported illnesses in Canada.

Products bearing date codes of Oct/17/07, Oct/20/07, Oct/24/07, Nov/04/07, Nov/10/07, Nov/11/07 are affected by this alert.

They include Tortillas de Harina, Fajita Size, Tortillas de Harina 6", and Burritos #2, 3, 3 ½ and 4.
