According to the World Health Organization (WHO), aflatoxins contaminate approximately 25% of the world's food supply, with aflatoxin B1 being the most toxic and carcinogenic. Chronic, low-level exposure to this mycotoxin, commonly found in contaminated cereals and nuts, can lead to serious and irreversible long-term health problems in both humans and animals.
