Abstract
Aflatoxins are a family of poisonous, mutagenic, and carcinogenic mycotoxins that contaminate a wide range of foods and agricultural goods. Aspergillus species, such as Aspergillus flavus, and Aspergillus parasiticus are the most common producers. Aflatoxin generation can occur at any point of the food chain, including pre-harvest, drying, storage, transit, processing, and handling, if conditions are favourable for fungus to create toxins. It is classified into six main types which are Aflatoxin B1, Aflatoxin B2, Aflatoxin G1, Aflatoxin G2, Aflatoxin M1 and Aflatoxin M2. In Nigeria, Aspergillus species that produces aflatoxin has been isolated from agricultural products such as cereals, spices, locally fermented food, oil-seeds, and animal products. Aflatoxin contamination is high due to poor storage of food crops and lack of awareness of aflatoxins contamination among farmers, marketers and the consumers of these goods. Locally fermented foods such as ogiri, ugba, ogi-baba, and iru have been said to be contaminated by aflatoxin. Preventive measures should be carried out by the policy-making bodies to create awareness and sustain ongoing measures to effectively manage aflatoxin contamination in Nigeria so as to reduce the health risk of aflatoxins on the people and economy of the country.
