Case report: Coccidiosis and lead poisoning in Canada geese

Abstract

Four dead Canada geese (Branta canadensis L.) collected at the Prime Hook National Wildlife Refuge, Delaware were found to have both marked duodenal lesions of coccidiosis and high levels of lead in the liver. Although only one goose had lead shot in the gizzard, all four had levels of lead in the liver suggestive of lead poisoning.
