Grocery store chain Hy-Vee says it's recalling some bags of Hy-Vee dog food that might contain a toxin commonly found in corn.

The Iowa-based company says tests conducted by the Iowa Department of Agriculture indicated higher-than-normal levels of aflatoxin in some samples of the dog food made at a Kansas City plant operated by Pro-Pet, LLC.

Aflatoxins are chemicals produced by fungi on corn that can sicken pets. Symptoms include sluggishness or lethargy combined with a reluctance to eat, vomiting, yellowish tint to the eyes or gums and diarrhea.

The recalled products carry three different "best by" dates and were distributed to Hy-Vee stores in Iowa, Illinois, Missouri, Kansas, Nebraska, South Dakota, Minnesota and Wisconsin between October 26th and January 11th.
