A method for decontaminating a biological material contaminated with a trichothecene mycotoxin bearing a 3-hydroxy group, such as deoxynivalenol or vomitoxin, involves oxidation or epimerization of the 3-hydroxy group to convert the mycotoxin into a product with reduced toxicity. The method includes exposing the biological material to a first enzyme having activity to oxidize the 3-hydroxy group of the trichothecene mycotoxin to a 3-oxo group. The oxidized product can be exposed to a second enzyme having activity to reduce the 3-oxo group to a 3-hydroxy group having a stereochemical configuration different from that of the 3-hydroxy group of the trichothecene mycotoxin.
