Stricter guidelines studied for pet products

WASHINGTON — Products intended to treat cats and dogs for fleas and ticks kill hundreds of pets each year and injure tens of thousands, the Environmental Protection Agency said Wednesday as it outlined plans to make the products safer.

The EPA said it will develop stricter testing and evaluation requirements for flea and tick treatments that are applied to a pet’s skin. The agency also will begin reviewing labels to determine which ones need to say more clearly how to use the products.

The EPA’s effort follows increasing complaints from pet owners that "spot-on” products have triggered reactions in dogs and cats, ranging from skin irritation to neurological problems to deaths. Cats and small dogs appear particularly vulnerable, the EPA said, especially when given products intended for larger animals.

Steve Owens, assistant administrator of EPA’s Office of Prevention, Pesticides and Toxic Substances, said new restrictions will be placed on flea and tick products, with additional changes for specific products likely — including possible changes in some product formulas.

"These are poisons,” Owens said. "These are products designed to kill fleas and ticks — and they do their jobs.”

Pet owners "need to carefully read and follow all labeling before exposing your pet to a pesticide,” Owens said.

The agency announced last April it was increasing scrutiny of topical flea and tick products because of the growing number of bad reactions reported. A 2009 study linked to proper use of topical flea and tick products were mild.
