bracken poisoning

poisoning of animals after eating Pteridium aquilinum (bracken). In monogastric animals it consists of severe intoxication due to enzymatic destruction of thiamine by a thiaminase present in the plant; in ruminants it is apparently due to a dialyzable small molecule that causes bone marrow hypoplasia and eventual death. See also enzootic bovine hematuria, under hematuria.
