Aflatoxins and Food Contamination

S&TMycotoxins and Food SafetyFactual singleEasyStatic

Question

Improper handling and storage of cereal grains and oilseeds result in the production of toxins known as aflatoxins which are not generally destroyed by normal cooking process. Aflatoxins are produced by (a) bacteria (b) protozoa (c) moulds (d) viruses

Options

a

bacteria

b

protozoa

c

moulds

Answer
d

viruses

Explanation

Aflatoxins are mycotoxins (fungal toxins) produced by certain species of molds, particularly Aspergillus flavus and Aspergillus parasiticus. These fungi grow on improperly stored grains and oilseeds under conditions of high moisture and temperature. Aflatoxins are stable compounds that are not destroyed by normal cooking processes, making them a significant food safety concern. They are known carcinogens and can cause serious health problems. Bacteria do not produce aflatoxins; they produce different types of toxins. Protozoa and viruses are also not producers of aflatoxins. Only fungi and molds produce these specific mycotoxins. Proper storage in dry conditions prevents mold growth and aflatoxin formation. > Aflatoxins: mycotoxins from Aspergillus molds — heat-resistant toxins in improperly stored grains. Answer: (c).
