Abstract |
In May 2016, thirteen dogs housed in backyards within a single neighborhood were reported to have developed convulsions and died within a 24 h period. An investigation of the scene by law enforcement resulted in submission of eight dogs for postmortem examination. It was suspected that a rapid acting toxin was the cause of death. A gas chromatography-mass spectrophotometry (GC-MS) protocol combined with thin-layer chromatography that allows screening for common convulsants failed to identify a toxin in either pooled gastric content or liver samples from select cases. After consultation with a veterinary toxicologist, sodium fluoroacetate poisoning was investigated. Sodium fluoroacetate, also known as 1080, is a pesticide that was available in the United States from the 1940's to the 1970's, but since 1972 has been banned or under EPA restricted use. When gastric content was re-tested using a GC-MS protocol with selective fluoroacetate ion monitoring and carbon 14 radiolabeling to facilitate quantification, 379 ppb sodium fluoroacetate was detected in a pooled gastric content sample. In spite of its banned status, sodium fluoroacetate remains a rarely reported cause of malicious poisoning in domestic dogs in the United Sates. This compound is highly toxic and is capable of causing death in dogs, humans, other mammals, and insects in ingested quantities as small as a few droplets. Even when geographic or historical proximity to a source is not evident, this intoxication should be considered in dogs exhibiting compatible clinical signs. Language: en |
