Sodium monofluoroacetate (CH2FCOONa), also known as 1080, domestic use is currently restricted to livestock-protection collars on sheep and goats to selectively kill depredating coyotes. The chemical is readily absorbed by ingestion or inhalation. At lethal doses, metabolic conversion of fluoroacetate to fluorocitrate results in the accumulation of citrate in the tissues and death within 24 h from ventricular fibrillation or from respiratory failure; no antidote is available. At sublethal doses, the toxic effects of 1080 are reversible. Primary and secondary poisoning of nontarget vertebrates may accompany the use of 1080. The use of 1980 seems warranted in the absence of suitable alternative control methods.
