Periodically, questions arise from pet owners regarding mercury in pet foods. They are curious why mercury is put in their pets’ diets or, more emphatically, why poisons are being added to their food. Nothing could be further from the truth. No pet food company is adding mercury as an ingredient to their foods and none would want to cause harm to their pet customers. Many times, these questions come after the publication of a report or website proclaiming their analytical results from samples of pet foods which supposedly contain non-nutritional metals, like mercury. So, how is mercury finding its way into our pet foods and do we need to be alarmed?

While events that conspired to sweep petfood into the Food Safety Modernization Act of 2011 were not exclusively pathogen related, the net result has been an almost singular focus on eliminating Salmonella in petfood. Before 2007, the only area in the news that seemed to be affected by Salmonella was poultry products (i.e., chicken and eggs).

Bisphenol A: incidental non-ingredient

In the production of petfoods—no different than human foods—there are a number of compounds that make their way into the food that aren’t a part of the formula/recipe or stated on the ingredient listing. This is nothing underhanded or disingenuous, merely a function of the process, package and regulations.
