The vast majority of the pet food products we tested drastically exceeded the regulations and guidelines for human consumption for toxin threshold for arsenic and lead. Human consumption thresholds set by third parties, including the Environmental Protection Agency, World Health Organization and state laws like California Proposition 65, were established after diseases and birth defects were directly related to those levels of toxin consumption. Though more research is needed on the impact of most toxins on animals, the research that does exist has eerily similar impacts on companion animals, and animals regularly used in a laboratory settings, like mice and rats.
The fact that there isn’t a mandatory threshold for these environmental toxins and contaminants for animals does NOT mean these contaminants aren’t dangerous for cats and dogs to consume.
