WEST DES MOINES (AP) — 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 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 plant operated by Pro-Pet LLC.

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“Best By” dates of Nov. 19, Nov. 24 and Nov. 25 and were distributed to Hy-Vee stores in Iowa, Illinois, Missouri, Kansas, Nebraska, South Dakota, Minnesota and Wisconsin between Oct. 26 and Jan. 11. For more information, go to www.hy-vee.com.
