Correct Option (C)
Aflatoxins are a group of toxic compounds classified as mycotoxins. They are primarily produced by certain species of fungi, commonly known as moulds, belonging to the genus Aspergillus, particularly Aspergillus flavus and Aspergillus parasiticus. These moulds proliferate on agricultural commodities such as cereal grains, oilseeds, and nuts when stored under warm, humid, and improper conditions. Aflatoxins are known for their carcinogenic properties and are not effectively destroyed by typical cooking processes, underscoring the importance of proper storage and handling.
Incorrect Options:
1) Bacteria: Aflatoxins are not produced by bacteria. Bacteria are single-celled prokaryotic organisms, and while some bacteria produce toxins, aflatoxins are specifically fungal metabolites.
2) Protozoa: Protozoa are single-celled eukaryotic organisms, distinct from fungi, and are not involved in the production of aflatoxins.
4) Viruses: Viruses are obligate intracellular parasites that replicate within host cells and do not produce toxins like aflatoxins. Their mechanism of action and biological structure are entirely different from toxin-producing moulds.
