MSX is a microscopic parasite that kills oysters but is not harmful to humans. It is a protozoan, or one-celled animal which thrives in areas of high salinity water. Death of oysters occurs mostly in the warm season with minor losses occurring in winter. MSX is now in its tenth year in Virginia with no reduction of its activity.
