Correct Answer - Option 4 : Milk and dairy products

Correct option : 4

Aflatoxin M1 is found in Milk & Milk Products. Aflatoxins (AFs) are a major class of mycotoxins produced primarily by Aspergillus species including Aspergillus flavus, Aspergillus parasiticus, and Aspergillus nomius. 

Aflatoxin B1 (AFB1), aflatoxin B2 (AFB2), aflatoxin G1 (AFG1) and aflatoxin G2 (AFG2) are the major classes of AFs.

Aflatoxin M1 is a hydroxylated metabolite of (AFB1) Aflatoxin B1, that is excreted in milk in the mammary glands of both humans and lactating animals.

1. Aflatoxin B1 & total Aflatoxin are found in dried fruits and nuts.

2. Aflatoxin B1, B2, G1, G2 are found in cereals and grains & honey.

3. Aflatoxin M1 is found in milk and milk products.

 

1. The presence of Aflatoxin M1 in milk and milk product is an important issue, especially in developing countries.
2. FSSAI has fixed the limit of aflatoxin M1 at 0.5 µg/kg for milk.
3. The most popular method for Aflatoxin M1 analysis in milk and milk products is HPLC (High-performed liquid chromatography).
