White solid; [HSDB] White powder; [MSDSonline]


Trichothecene mycotoxin found in Fusarium tricinctum; Thought to be used in the past as a chemical warfare agent in Southeast Asia; [Merck Index] Produced by various Fusarium fungi; Human exposure has occurred from consumption of contaminated cereals; [HSDB] Produced mainly by Fusarium sporotrichioides; Occasionally found on cereals like wheat and maize; Caused mass human poisonings in Siberia in the last century; [IARC]


May cause severe irritation and tissue necrosis to skin and mucous membranes; Topical application has caused systemic toxicicity and death in animal studies; [Merck Index] A strong skin irritant; May cause blistering and necrosis to skin; Trichothecene mycotoxins causes bone marrow suppression, leukopenia, immunosuppression, and secondary sepsis; [HSDB] Within minutes, the effects of T-2 mycotoxin include irritation of the skin and injury to the GI and respiratory tracts. In severe cases patients have skin necrosis, fever, ataxia, epistaxis, chest pain, wheezing, hemoptysis, bone marrow depression, hemorrhagic diathesis, and shock. [Weinstein, p. 104]
