We all worry about our pets being exposed to cleaners, air pollution, and water contaminants. After all, we live in an environment that is filled with thousands of synthetic chemicals, from auto emissions to floor cleaners, plastics to wood protectants, paints and non-stick pans. Every day we are exposed to these substances on a minute-by-minute basis. It makes sense that our pets would be exposed to them as well. But until now, no one has studied this. A new study by the Environmental Working Group set out to answer just how much chemical exposure our pets have.
The study, performed at a veterinary facility in Virginia, tested urine and blood samples of 20 dogs and 37 cats that ranged in age from pediatric to geriatric. The results were startling. Of 70 industrial chemicals tested, dogs and cats overall were positive for 48 of them (69%). 43 of those chemicals were at higher levels than are normally found in people, and many were substantiall7 (2.4 to 23 times) higher than those found in people. Why so much higher? Likely due to our pets’ lifestyles–living close to the floor, eating things off the floor, licking carpets or furniture, and grooming among others.
The chemicals tested fell into 3 main groups:
- Teflon chemicals, also known as perfluorochemicals, are those used in teflon and grease and stain-proofing products. These were the chemicals that tested highest in dogs. Heating teflon-coated pans allows gasses to be released that can be inhaled into the system or land on the fur, where they can be ingested by grooming. These are also found in products like scotch-guard, stain resistant carpets and fabrics, and other similar products.
- Phthalates, used as plasticizers and plastic softeners, are found in plastic toys, plastic bottles, shampoos, and a wide range of other products.
- Fire retardants, found in bedding, house dust, linings of pet food bags, foam furniture, and treated fabrics (even including children’s pajamas). They are also found in air and water, and have accumulated in seafood secondary to water contamination. These were found in the highest levels in cats, most likely due to their propensity to groom themselves, but may also be elevated because they eat more fish in their diets.
Before you throw out everything in your house and build a bubble around it, it is important to put this information in perspective. Because there are virtually no safety standards in the industrial chemical industry, we do not know what levels of these chemicals may be safe or harmful. While some of these chemicals have been linked to development of specific diseases, most have not. And since living in a bubble is not exactly an option, you and your pets will be exposed to some of these substances. However, there are some things you can do to keep yourself and your pets safer:
- Use bottled water. This does not guarantee your pet won’t be exposed to synthetic chemicals but bottled water is generally more “pure”. Keep in mind bottled water can have higher levels of natural chemicals such as arsenic.
- Buy high-quality pet food. As we found out from the pet-food recall of a few years ago, chemicals like melamine may be added to pet food as a cheap way to boost protein content. Reputable companies will do their best to avoid ingredients that may have contamination (such as wheat gluten). These foods are generally better for your pet’s overall health anyway.
- Avoid plastic food and water bowls. Use natural ceramic or glass with no glazes or coatings.
- Avoid plastic toys. Buy toys made of natural materials.
- Choose beds, blankets, and scratching posts of natural materials. Make sure these items don’t have fire retardants on them. (You will need to read labels and ask).
- Cook with cast iron pans and avoid non-stick if at all possible. This is vital if you have birds, as teflon fumes will kill birds quickly and without warning. For other pets, if you can’t avoid using non-stick then run exhaust fans and open windows as much as possible, and keep your pets far away from the kitchen.
- Clean green. There are many “green” cleaners that use essential oils and other natural substances and are much safer for pets. Be aware that essential oils may have strong odors that may become overwhelming to our pets’ acute sense of smell so use sparingly and remember if it smells too strong to you, its probably way to strong to your pet.
- Wipe your pet down with a damp cloth once a day. This will help remove some residues from your pet’s fur.
It is impossible to avoid chemicals and they aren’t all “bad”. After all, they allow us to live with all the conveniences of modern technology, travel, medicine, and gadgets we have. But a little prudent adjusting of your pet’s exposure can’t hurt.
