Fluoroacetamide (1081) oisoning in wild birds.

An outbreak of poisoning in four greylag geese (Anser anser) and 35-45 teal (Anas crecca) is described. Laboratory findings led to the conclusion that a wheat bait containing the rodenticide fluoracetamide (1081) caused the poisoning. Circumstantial evidence incriminated fluoracetamide as the cause of death in white-fronted geese (Anser albifrons), mallards (Anas platyrhynchos), and chukars (Alectoris chukar).
