Commercial dog food contains ‘alarming’ levels of lead, mercury and other contaminants

Commercial Dog Food: What Pet Owners Need to Know

A recent investigation by the Clean Label Project has revealed that many popular commercial dog foods contain disturbing levels of heavy metals, acrylamide, and other contaminants. This has raised serious concerns among pet owners about the safety of the food they provide to their pets.

Key Findings

Dog foods tested contained three to 13 times more heavy metals than human foods evaluated over the past decade.
Exposure to heavy metals such as lead and cadmium has been linked to higher cancer rates in dogs, with approximately 1 in 4 dogs expected to develop cancer in their lifetime.
Dry dog food (kibble) had the highest levels of contaminants, followed by air- and freeze-dried foods, whereas fresh and frozen dog foods showed significantly lower contamination levels.
Lead and mercury levels in dry dog food were found to be about 21 times higher than those in fresh and frozen products.
Nearly 81% of the commercial dog foods tested exceeded the maximum tolerated level of mercury, while 100% exceeded the level for lead.

Acrylamide Levels

Acrylamide, a cancer-causing compound, was found to be present in dry dog food at levels about 24 times higher than in fresh or frozen options. One product even tested at 780 parts per billion of acrylamide, a level typically associated with extremely processed foods.

Recommendations for Pet Owners

For pet owners, several steps can be taken to mitigate these risks:

Consider rotating brands of dog food to add variety to your dog's diet and potentially reduce exposure to contaminants.
If possible, incorporate fresh or frozen dog food, which showed lower contaminant levels.
Consult with your veterinarian to discuss dietary options that suit your pet's health needs.
Stay informed about the pet food brands you choose and their testing practices concerning contaminants.

The Importance of Testing

One major issue raised is the lack of comprehensive studies focused on the long-term effects of heavy metal exposure in dogs. Pet food companies may need to improve testing protocols to ensure the safety of their products for pets.
