High Levels of Lead, Mercury Found in Commercial Dog Food

A recent investigation revealed alarming levels of heavy metals, including lead and mercury, in popular commercial dog foods. Conducted by the Clean Label Project, this study highlights the potential dangers pet owners face in choosing dog food. The findings are particularly concerning as many dogs are fed the same brand of dry food daily, which can lead to significant health risks.

Heavy Metal Contamination in Dog Food

The investigation indicated that dog foods contained three to thirteen times more heavy metals compared to human food. Molly Hamilton, executive director of Clean Label Project, emphasized that pet owners have the right to worry about their pets’ safety when selecting dog food.

Key Findings

• Dog food showed 21 times higher lead and mercury levels than fresh and frozen alternatives.
• Kibble had over 13 times more arsenic and six times more cadmium than fresh and frozen dog foods.
• More than 81% of commercial dog foods exceeded regulatory mercury limits.
• 100% of samples tested had lead levels surpassing maximum tolerable limits.
• About 1 in 4 dogs will be diagnosed with cancer in their lifetime.

The Risks of Dry Dog Food

Dry dog food, or kibble, was found to have the highest levels of contaminants. The study examined 79 samples of various dog food types, including air-dried, freeze-dried, and fresh products. Notably, fresh and frozen foods, which account for a growing segment of the market, were less contaminated.

Dr. Joseph Wakshlag, a veterinary nutrition specialist at Cornell University, noted that while fresh and frozen foods have lower heavy metal levels, they require dogs to consume larger quantities to meet nutritional needs. Consequently, this could increase exposure to heavy metals.

Understanding Acrylamide Levels

The investigation further identified high acrylamide levels in dry dog food, with some samples presenting levels up to 780 parts per billion. Acrylamide is a chemical produced when foods are cooked at high temperatures and is considered carcinogenic.

Chemicals of Concern

• Acrylamide associated with fried and baked foods can adversely affect animal reproductive health.
• Bisphenol A (BPA) and Bisphenol S (BPS) levels were found to be highest in dry dog foods, potentially impacting human health.
• Di(2-ethylhexyl)phthalate (DEHP), a plasticizer, may contribute to serious health risks in humans.

Recommendations for Pet Owners

Given the findings, pet owners are encouraged to be cautious about their dog’s diet. Switching to fresh or frozen dog foods may be beneficial, provided it’s feasible for both the pet and pet owner. Hamilton suggests rotating different brands of dry food to mitigate the risks associated with long-term exposure to contaminants.

In conclusion, the investigation sheds light on the hidden dangers in commercial dog food. With rising concerns over heavy metals and other harmful substances, pet owners must remain vigilant in choosing safe options for their furry companions.
