We describe a composition comprising a non-digestible oligosaccharide for the treatment, prevention or alleviation of a trichothecene mycotoxin exposure associated condition. The non-digestible oligosaccharide may comprise a galactooligosaccharide and/or fructooligosaccharide. The non-digestible oligosaccharide may comprise a short chain galacto-oligosaccharide (scGOS) and/or short chain fructooligosaccharide (scFOS). The trichothecene mycotoxin exposure associated condition may be associated with exposure to deoxynivalenol.
