Dog Food Ingredients Matter

It’s hard to avoid salmonella in dog food, but not unhealthy ingredients.

What ingredients to look for in dog foodTime, yet again, to reassess your dog's diet. A growing number of dry dog foods are being recalled in the wake of a discovery of salmonella contamination at a Diamond Pet Food facility in South Carolina.

Unlike the melamine-in-pet-food scandal that killed hundreds of dogs and cats in 2007, this tainted dog food hasn’t resulted in any illnesses of pets yet, but it has sickened 14 people in nine states, due to contact either with dogs or dog food. Five of those people have been hospitalized.

The recall, which started in April 2012, went on to involve 13 brands of food distributed mostly in the Eastern United States:

  • Wellness Complete Health Super5Mix
  • Canidae Dog
  • Natural Balance
  • Diamond Pet Food Chicken Soup for the Dog Lover’s Soul
  • Diamond Pet Food Country Value
  • 4Health
  • Diamond Professional
  • Diamond Premium Edge
  • Diamond Naturals
  • Diamond Taste of the Wild
  • Kirkland Signature Super Premium
  • Kirkland Signature Nature’s Domain
  • Apex Chicken and Rice Dog

Diamond hasn't released any information as to the source of the salmonella, whether it was the meat or another ingredient, which makes it difficult for pet owners to know which ingredients on the label should raise red flags when it comes to product safety. "It could be an ingredient, it could be the equipment," says Robert Downey, owner of the holistic dog-food brand Annamaet. "Not too long ago, a pet company had to recall their product because it was the packaging that tested positive for contamination."
