Veterinarians Asked to Report Pesticide Poisoning Incidents

(Beyond Pesticides, January 2, 2009) Household pets and other animals are commonly exposed to toxic pesticides in lawns and parks, from homeowner use of bug sprays, in contaminated air or water, or from flea and tick control products, potentially poisoning the animal and causing acute and chronic health effects. A new website has been designed for veterinarians to help track these pesticide poisoning incidents.

The incident reporting website is part of the American Veterinary Medical Association (AVMA) webpages. It was developed by the National Pesticide Information Center (NPIC) with input from the U.S. Environmental Protection Agency’s (EPA) Pesticide Program, AVMA’s Clinical Practitioners Advisory Committee and Council on Biologic and Therapeutic Agents “to capture the optimal amount of relevant information using a form that is quick for busy practitioners to fill out.” The data is to be evaluated by EPA.

According to EPA, “Most of the reports of more severe pesticide-related incidents EPA receives are neurological or dermatologic in nature. The reports from veterinarians will help improve the quality of all animal incident data.”

Numerous studies have documented the risk of pesticides to pets over the years. A 1991 National Cancer Institute study, finds that dogs whose owners’ lawns were treated with 2,4-D, four or more times per year, are twice as likely to contract canine malignant lymphoma than dogs whose owners do not use the herbicide. Exposure to herbicide-treated lawns and gardens increases the risk of bladder cancer by four to seven times in Scottish Terriers, according to a study by Purdue University veterinary researchers published in the April 15, 2004 issue of the Journal of the American Veterinary Medical Association. Research published in the December 1988 issue of Preventive Veterinary Medicine links hyperthyroidism in cats to flea powders and sprays, lawn pesticides and canned cat food. Allethrin, a common ingredient in home mosquito products (coils, mats, oils and sprays) and other bug sprays, has been linked to liver problems in dogs, according to a 1989 study by the World Health Organization. The 1989 edition W.C. Campbell Toxicology textbook reports that chronic exposure to abamectin, an insecticide often used by homeowners on fire ants can affect the nervous system of dogs and cause symptoms such as pupil dilation, lethargy, and tremors. According to 2004 statistics compiled by the American Society for the Prevention of Cruelty to Animals’ Animal Poison Control Center, 22% of approximately 880 cases of pet birds being exposed to common household items involved pesticides (including rat bait and insecticides).

“I can think of numerous cases over the years of abnormal neurologic signs in dogs after exposure to ‘benign’ herbicides and a pretty severe contact dermatitis in a cat after exposure to a pesticide,” states an ER vet in California. “I will try to encourage my colleagues to report any questionable adverse event in the future.”

If you suspect your pet has been poisoned, contact the Animal Poison Control Center at 888-426-4435. Encourage your veterinarian to document the pesticide poisoning through the new AVMA website. To be sure the incident does not go undocumented, complete Beyond Pesticides’ Pesticide Incident Report.

    I was under the understanding that the 1991 study mentioned above was refuted by a peer group that said the study was flawed. I’ve seen this repudiation in a number of other documents and wonder why the 1991 study is still listed as valid.

    In the absence of a citation for the peer group’s evaluation, the Environmental Working Group has addressed this issue on their pets’ health page: http://www.ewg.org/node/26239.

    We took our cats to a vet and told him about the exposure of them and our son to multiple pesticides and herbicides.
    If he had listened, and given our cat atropine, it might have been spared a slow horrible death. I decided to treat the other cat myself with iv’s and medication……..it was yellow, dying,neurologically impaired, and lost half its body weight in Feb to March….but is now on the mend.
    Why does Florida continue to turn a blind eye to children and pets who are being harmed and killed on a daily basis?!!!
    Cosmetic lawn and pond care should be more highly regulated. Compliance does all they can to enable big business to continue to poison us.

    I have spraying of Thiamethoxam (Actara) on Pecan trees within the “air drift” of my home. I have lost one dog and another is declining now as well as I have health issues which could be related to the above insecticide. My immediate plan is to contact my state’s Dept of Ag and have soil sampling done.

    A friend’s property tested positive and she lives 1.5 miles west and the pecan orchards are inclusive of both our properties.

    I don’t know if this has any connection with my dogs’ problems (neurological) but I will keep this site in mind if things proof positive.
