Sarcocystis: Rice Breast Disease In Waterfowl
A publication of the U.S. Fish and Wildlife Service

When hunters notice an abnormality or apparent disease in wild game they are preparing for consumption, they naturally have questions regarding their observation – particularly how it might affect their own health or the health of people consuming the meat.

Sarcocystis, which causes very prominent changes in the breast muscles of waterfowl, is one such disease. Wildlife managers are frequently asked about this disease and the risks associated with handling or eating affected birds. This leaflet will answer the most commonly asked questions about Sarcocystis in waterfowl.
