You may have seen some stories in the news lately about small amounts of euthanasia drugs getting detected in some popular pet food brands.  How does this type of drug end up in dog and cat food?  The answer is obvious but may come as a surprise to many pet owners.

A recent article on the website Gizmodo explains why the sedative pentobarbital, which is commonly used in euthanasia, has been found in at least 27 brands of pet food.  No, pet food companies are not deliberately adding it to their food, but it is ending up in food via third-party suppliers of ingredients used in the food.

Veterinary experts explain that the pentobarbital is coming from euthanized animals, usually horses, that go from farms to animal rendering operations, and eventually, to pet food manufacturers.  The FDA has been aware of this issue since the 1990s, so pentobarbital in pet food is not new.

This recent spotlight on the issue has caused many pet owners to wonder where the meat used in their animals’ food is actually coming from.  The pet food industry says that most makers source meat from livestock slaughtered in the same facilities used for human food.

The problem occurs when some of their suppliers use cheap ingredients as a way to cut expenses, such as euthanized and rendered farm animals like horses, as evidenced by the pentobarbital.

The drug amounts in the food are very small, and although there is a new awareness of the issue, it is unlikely that it will ever completely disappear from all pet foods, given the economic realities of the pet food industry.

What can you do to ensure that your pet is eating quality food?  Talk to your vet about the best pet food options for your individual pets, educate yourself on how to read and understand pet food labels, and be sure to keep track of all pet food recalls and withdrawals via the FDA’s pet food recall webpage.
