Cypermethrin is very toxic to cats which cannot tolerate the therapeutic doses for dogs. Willoughby, OH. Type I pyrethrins bind to the sodium channels on nerves and alter the voltage-dependent gating kinetics. As a consequence, cypermethrin remains much longer in the cat's organs than in dogs or other mammals and can be fatal in large doses. Chlorpyrifos is undergoing a phase out in “around the home” use products in both the US and Canada due to concerns about neurological effects in children. Lethal Dietary Toxicities of Environmental Contaminants to Coturnix, Technical Report Number 2. Interspecies differences in sensitivity may be explained by differences in exposure and differences in metabolization rate. Many of the toxicity studies were carried out approximately 20 years ago and do not meet modern standards of design or reporting. (Weil, 1997) In toxicity studies, the application of Frontline® spray to dogs and cats at a dose five times higher than recommended for 6 months did not cause any clinical, biochemical, hematological, or cutaneous abnormalities. According to the manufacturer of Combat® Roach Control System (1.65% hydramethylnon) a medium-sized (20 kg) dog would experience adverse effects from the bait itself only after eating an amount equivalent to 250 trays. Fikes JD: Feline chlorpyrifos toxicosis. SDS Biotech Corporation Animal Health Business. 200 300 W.B. AChE levels can be checked using serum, plasma, or whole blood. Provide oxygen and ventilatory support as needed for animals in respiratory distress. Once stabilized, a bath with liquid dish washing detergent should be given. This causes reversible prolongation of sodium conductance in the nerve axons and results in repetitive nerve discharges. Journal of Pharmacology and Experimental Therapeutics 285:731-738, 1998. Cypermethrin toxicity in a Spitz dog. (Fikes, 1992) Cats may also have delayed signs 1 to 5 days post topical exposure. American Assn Veterinary Diagnosticians 27th Annual Proceeding, 1984; 383-402. It was administered to the tail skin of female Wistar rats, 4 hours daily for 28 days. Meister Publishing Co, Willoughby, OH, 1985. (Webster, 1999). (Kidd, 1991). Painesville, OH. Meister, R.T., (ed.). Casida JE, Gammon DW, Glickman AH, et al: Mechanisms of selective action of pyrethroid insecticides. J Assoc Off Anal Chem 1985;68:71-75. Imidacloprid To the best of our knowledge this is the first report describing pyrethroid toxicity in a dog. Selamectin: An endectocide for companion animal use. Hydramethylnon appears to be quite safe in mammals as the oral rat LD50 is 1100 to 1300 mg/kg. Other signs include anorexia, ventroflexion of neck, change in personality, hyperesthesia, and hyperactivity. Methomyl Oral Dermal These baits contain large amounts of sugar that make it very palatable to dogs and other animals. Each pet responds differently to products that contain permethrin. Alpha-Cypermethrin Toxicity in a Labrador Dog: A Case Study. Percentage of E rosette forming cells and the migra­ tion index were either unchanged or displayed insignificant dose-dependent values. It is used to control aphids, leafhoppers, thrips, beet flies, spider mites, and coffeeleaf miners. Treatment for dermal exposure is bathing with liquid dish washing detergent (avoid human exposure by the use of heavy-gauge rubber gloves). U.S. Environmental Protection Agency. Royal Society of Chemistry Information Services, Cambridge, UK, 1991 (As Updated).10-2 (Fikes, 1990) Treatment of symptomatic patients consists of stabilizing the animal and controling seizures (with diazepam, methocarbamol, or barbiturates) before proceeding with other treatments. Hydramethylnon is highly toxic to fish and nontoxic to birds and honey bees. Results of a pharmacovigilance survery one year after launch. These signs are rarely seen in dogs. Disulfoton (Bay S276, Disyston, Disystox, Dithiodemeton, Dithiosystox, Frumin AL, Solvigram, Solvirex) is a selective, systemic organophosphate insecticide and acaricide that is especially effective against sucking insects. Treatment for dermal exposure is bathing with liquid dish washing detergent (avoid human exposure by the use of heavy-gauge rubber gloves). (Kidd, 1991) Although methomyl does not appear to accumulate in any particular body tissue, it may alter many other enzymes besides cholinesterase. MacDonald JM: Flea control: An overview of treatment concept of North America. The dog presented in this case was exposed to 2 different Cats have shown some depression, ataxia and salivation when saturated with the tetrachlorvinphos sprays, but this may be due to the alcohol content and the taste of the product. Compend Contin Educ Pract Vet 21(suppl):32-35, 1999. Your dog goes swimming in a lake or body of water with fish ; Even worse, the pyrethroids found in flea bandana products are also highly toxic to: Bees; Birds; Aquatic wildlife. Give 1/4th of the initial dose IV and the rest IM or SQ. Oral Dermal U.S. National Library of Medicine. Cats are more likely than dogs to develop pyrethroid toxicosis. Pesticide-grade permethrin is toxic to cats. Animal studies show that lindane is readily absorbed through the gastrointestinal tract, skin, and lungs. Fikes JD: Feline chlorpyrifos toxicosis. If the cat is actively seizuring, barbiturates, propofol or inhalant anesthesia can be used. Sensitivity to chlorpyrifos varies with species. Give a preanesthetic dose of atropine (0.02 mg/kg IV for dogs and cats) and monitor the response. Mouse (Evans et al, 1984). Current Veterinary Therapy XI, Kirk RW and Bonagura JD, ed. 5.93; Anand Agricultural University; Download full-text PDF Read full-text. Alpha-cypermethrin prolonged the time constants for the recovery from inactivation kinetics of IA. However, the time of "aging" varies with the compound and so 2-PAM may be effective even days after exposure. Registration Standard (Second Round Review) for the Reregistration of Pesticide Products Containing Chlorpyrifos. Treatment consists of atropine, and supportive care to control the seizures.
