Washington  (ABC) The U.S. Food and Drug Administration said multiple samples of Sportmix dog and cat foods made by Midwestern Pet Food, Inc., were tested by the Missouri Department of Agriculture and found to have potentially fatal levels of aflatoxin. The toxin is produced by the mold aspergillus flavus, which can grow on corn and other grains used in pet foods, according to CBS.

ABC reports aflatoxin can be present even if the mold isn’t visible. Symptoms of aflatoxin poisoning include sluggishness, loss of appetite, vomiting, jaundice (yellowish tint to eyes, gums or skin from liver damage), and/or diarrhea. Some pets can suffer liver damage or die.

Nine different lots of dry pet food have been recalled that were sold online and in stores nationwide.
