The EPA announced that all flea collars will be free of the pesticide carbaryl by September 2010. The action came in response to a 2005 petition by the Natural Resources Defense Council requesting that the Agency withdraw use of the pesticide in pet collars because of the pesticide’s toxicity. Pet products containing carbaryl were voluntary withdrawn by manufacturers in 2006 except for of the Zodiac® brand, a division of Wellmark International (Eco-Fail). Carbaryl–also known as Sevin–Carbaryl, a carbamate, is a contact nerve toxin that inhibits the enzyme cholinesterase, with a resulting disruption of nerve impulse transmissions. Carbaryl causes an array of serious neurotoxic effects in animals, including irreversible neurological damage and behavioral disturbances, according to Beyond Pesticides. Eco-Win!
