Some isolates produce the Mycotoxin trichothecenes, which can cause disease in humans and animals. Trichothecenes targets the circulatory, alimentary, skin, and nervous systems. Also some species of Fusarium produces mycotoxin vomitoxin on grains, which produce disease by either ingestion or inhalation of the contaminated grains. It can be an opportunistic human pathogen causing allergic disease, eye, skin, and nail infections.
