Peanuts can cause cancer

This is probably true if the peanuts are highly contaminated with aflatoxins. However, in Australia, the level of contamination is very low and peanuts and peanut products are unlikely to be a significant cause of cancer.

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.
