Abstract
Mycotoxins are biologically active, toxic metabolites produced by toxigenic fungi
mainly belonging to Aspergil/us, Fusarium and Penicil/iumsp, which invade crops in the field
and may grow on foods during storage under favourable conditions of temperature and
humidity. Like other environmental pollutants, mycotoxins also adversely affect the health
and productivity in animals and poultry. Mycotoxicosis is a disease caused by a toxic fungal
metabolite known as "mycotoxin". Mycotoxins drew attention in the early 1960s when
aflatoxin, a mycotoxin produced by Aspergil/us sp., was discovered to be the cause of
disease in poultry and fish. Fungal growth is required for mycotoxin production in grain.
Fungi can infect and grow in grain prior to harvest, during storage or after inclusion in
finished feeds. Many mycotoxins are stable during milling and feed storage. Therefore toxins
can be present in grains after the fungi that produced them are dead. Thousands of
chemically distinct mycotoxins exist. lndividual fungal strains usually synthesize more than
one mycotoxin and these toxins often act synergistically. Aflatoxicosis, ochratoxicosis and
trichothecenemycotoxicosis are the most commonly seen mycotoxicoses in poultry.
