—Concludes that brevetoxicosis from exposure to red tide "was a component of and likely played a central role in the 1996 manatee epizootic." Such deaths can result from neurointoxication and/or hemopathy caused by chronic ingestion and/or inhalation of red tide toxins. Unlike the 1982 epizootic, ingestion of ascidians was not a prominent finding in the 1996 necropsies, wherein upper respiratory tract lesions were "the only severe and consistent inflammatory lesions seen".
