Aflatoxins are toxic compounds produced by certain molds, particularly those in the Aspergillus species. These molds can grow on various crops, including peanuts, corn, and tree nuts, especially in warm and humid conditions. Aflatoxins are harmful to humans and animals, as they can cause serious health issues, including liver damage and cancer. Exposure to aflatoxins typically occurs through contaminated food or feed. Regulatory agencies, such as the Food and Drug Administration (FDA), monitor and set limits on aflatoxin levels in food products to protect public health. Proper storage and handling of crops can help reduce the risk of contamination.
