Fusariotoxicosis from barley in British Columbia. II. Analysis and toxicity of syspected barley.

Fusariotoxin T-2, a trichothecene, was tentatively identified in barley samples which caused field outbreaks of mycotoxicosis in British Columbia. Geese died when fed the contaminated barley experimentally but mice were little affected after long term feeding. The methods used in the laboratory for trichothecene extraction and identification of T-2 toxin are described.
