Aflatoxin B1 (Aflatoxin B1) is a highly toxic secondary metabolite produced mainly by Aspergillus flavus and Aspergillus parasiticus under warm and humid conditions. It belongs to the difuranocoumarin group of mycotoxins and is recognized as the most toxic and carcinogenic aflatoxin. The International Agency for Research on Cancer (IARC) has classified Aflatoxin B1 as a Group I carcinogen, confirming sufficient evidence of carcinogenicity in humans.
Detection of Aflatoxin B1 refers to the qualitative and quantitative determination of its presence in food, feed, and raw materials using validated analytical methods. This detection is required to assess compliance with legally binding maximum limits. For example, European Union Regulation (EU) No 1881/2006 establishes maximum levels for Aflatoxin B1 in cereals, nuts, and derived products, making compliance mandatory for all food placed on the EU market. In the United States, the FDA enforces action levels for aflatoxins under the Federal Food, Drug, and Cosmetic Act, and products exceeding these limits are considered adulterated. Therefore, detection is a fundamental regulatory requirement rather than a voluntary quality measure.
