Toxicity to pets

Organophosphates (OP) and carbamates are insecticides that can result in severe poisoning to dogs and cats. Thankfully, the frequency of this type of poisoning is steadily decreasing (thanks to regulation by the EPA); however, Pet Poison Helpline still receives hundreds of calls a year about these insecticides. These insecticides are often mixed into other fertilizers or herbicides, and are commonly used by rose and flower gardeners. When these products are accidentally ingested by pets (or used maliciously to poison pets), severe clinical signs may be seen, including SLUDGE signs (which is the acronym for salivation, lacrimation, urination, and defecation). Other severe signs include hypothermia, hyperthermia, difficulty breathing, tremors, seizures, and death.

If you suspect your dog or cat has organophosphate poisoning or carbamate poisoning, contact your veterinarian and Pet Poison Helpline for immediate, life-saving treatment recommendations!
