CHICKASHA, Okla. (NewsNation Now) — A pet food company increased the number of brands recalled after an increase in the number of pets that died since the initial recall.

In December, NewsNation first reported Midwestern Pet Foods voluntarily recalled three varieties of Sportmix dog foods and cat foods after 28 dogs died after eating the mix, which has since increased to 70.

The recalled lots of food contained “potentially fatal levels of aflatoxin.” It’s a toxin produced by mold grown on corn and other grains. The affected products were distributed to online retailers and stores nationwide within the country, the U.S. Food and Drug Administration said.

The company expanded the recall on Jan. 11, increasing the number of brands included after 42 additional dogs died in the past two weeks.

“As of January 11, 2021, FDA is aware of more than 70 dogs that have died and more than 80 pets that are sick after eating Sportmix pet food. Not all of these cases have been officially confirmed as aflatoxin poisoning through laboratory testing or veterinary record review. This count is approximate and may not reflect the total number of pets affected,” the FDA said.

Officials said the affected Sportmix pet food products were manufactured by Midwestern Pet Foods in their Oklahoma plant in Chickasha.

The recall now includes all Midwestern Pet Foods dry dog and cat foods containing corn, manufactured in the company’s Oklahoma plant, and having an expiration date on or before July 9, 2022.

If you have one of the products listed above but do not know the lot code or expiration date, the FDA recommends that you stop using the product.

According to the FDA, pet owners should stop feeding their pets the food and consult their veterinarian, especially if the pet is showing signs of illness.

Symptoms in pets can include:

• Sluggishness
• Loss of appetite
• Vomiting
• Jaundice (yellowish tint to the eyes or gums due to liver damage)
• Diarrhea
• In some cases, pets may suffer liver damage but not show any symptoms.

If your pet has symptoms of aflatoxin poisoning, contact a veterinarian immediately. Even pets without symptoms may have suffered liver damage, so you may want to contact your veterinarian if your pet has eaten any of the recalled products. 

Pet owners can report suspected cases to the FDA.
