Explanation:

Aflatoxins are poisonous and cancer-causing chemicals that are produced by certain molds which grow in soil, decaying vegetation, hay, and grains. A mold is a fungus that grows in the form of multicellular filaments called hyphae. In contrast, fungi that can adopt a single-celled growth habit are called yeasts.
They are regularly found in improperly stored staple commodities such as cassava, chili peppers, corn, cotton seed, millet, peanuts, rice, sorghum, sunflower seeds, tree nuts, wheat, and a variety of spices.
When contaminated food is processed, aflatoxins enter the general food supply where they have been found in both pet and human foods, as well as in feedstocks for agricultural animals.
Animals fed contaminated food can pass aflatoxin transformation products into eggs, milk products, and meat.
