Throughout 25 states, about 10,000 cases of Eggo Nutri-Grain Whole Wheat Waffles are being voluntarily recalled because of possible contamination with the bacteria listeria.

Kellogg Co. announced Monday on its website that there have been no reports of illnesses, but officials learned of the potential problem after routine tests. Thus far, no other Eggo products are affected by this recall.

According to the Center for Disease Control and Prevention, listeria can cause serious infections in anyone with weakened immune systems. Children and the elderly are particularly vulnerable. The symptoms include severe headaches, high fever, abdominal pain, stiffness and diarrhea. Listeria can also cause miscarriages and stillbirths in pregnant women. In more serious cases, listeria can also cause death.

Officials ask for anyone who has eaten this product and experiences these symptoms to contact a physician. Listeria can be treated with antibiotics.

Officials noted that the recalled waffles are available in 10-count packs with "Best if used by" Nov. 21, 2017 - Nov. 22, 2017. People can find this date on the side of the package, or they can look for the UPC product code on the label.

Kellogg Co. officials are asking consumers to throw away the affected products and contact the company for a full refund at 1-800-962-1413 from 9 a.m. to 6 p.m. ET, Monday through Friday, or by visiting its website here.
