Mycotoxins are secondary metabolites of fungi, which may cause diseases in animals or humans. Aflatoxin B₁ is mycotoxin, which is known to frequently contaminate poorly stored food products destinated for human consuption. In nature, there exist microorganisms for which the aflatoxins are non-toxic. Aflatoxins are degraded through the microorganism’s activity and the obtained products are probably utilized in their metabolism or the microorganisms have ability to bind aflatoxins to their surface. Components of herbs and spices have antiaflatoxigenic properties. They inhibit fungal development and subsequent aflatoxin production. The study reviews literature concerning the detoxification of mycotoxins by microorganisms and components of herbs and spices.
