Acute copper toxicosis in the Canada goose.
Acute copper toxicosis resulted in Canada geese, Branta canadensis, following ingestion of copper sulfate at about 600mg/kg from a small man-made pond on a game farm. The lesions were those associated with copper toxicosis in other avian species. The primary pathologic change was necrosis and sloughing of the proventriculus and gizzard. A greenish discoloration of the lungs also occurred.
