Some moulds when they grow on food can produce toxins. Aflatoxins are produced in this way
and they can cause cancer in laboratory animals. There is no reason to doubt that they will do the
same in humans. Some aflatoxin-producing moulds can grow on peanuts, though such
contamination depends on many factors including growing, processing and storage conditions.
Peanuts in damaged pods are more likely to be contaminated than those in undamaged pods.
Surveys of aflatoxin contamination in peanut and peanut products in Australia show that levels are
generally absent or are within the limits set by health authorities.
