Pet food maker Stella & Chewy's issued a recall on July 2 for some of its products because a routine test found Listeria in a sample of its freeze-dried chicken dinner patties for dogs.

Listeriosis is a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes, the Centers for Disease Control and Prevention (CDC) reported. The disease primarily affects older adults, pregnant women, newborns and adults with weakened immune systems. However, in rare instances, persons without these risk factors can also be affected. For healthy individuals it can cause symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea. Listeria infection can cause miscarriages and stillbirths among pregnant women. Animals that become ill with Listeria could display symptoms similar to the ones listed above for humans.

The Milwaukee-based company said that there have been no reported cases of pet or human illnesses, according to FOX Business.

Consumers can look at the lot numbers and UPC codes on their pet food to determine if the food is part of the recall. If it is, then they can return the food for a full refund or dispose of it.

Some of the recalled items include some batches of the following:

  • Carnivore Crunch - Chicken Recipe
  • Carnivore Crunch - Turkey Recipe
  • Freeze-Dried Chewy's Chicken Dinner for Dogs
  • Freeze-Dried Chick, Chick, Chicken Dinner for Cats
