Interpretive Summary: Mycotoxins are poisons that are made by molds, and can sometimes occur in grains or other crops that are used for animal feed or human foods. Although much effort is made to prevent the molds that produce mycotoxins from invading crops, sometimes, because of adverse weather, insect invasion, or other conditions, the fungi grow and mycotoxins result. In this paper, a novel way to destroy mycotoxins, without damaging the crop, is presented. The method used ozone gas, generated from water, to chemically alter the mycotoxins. The effectiveness of the treatment was evaluated by methods to identify how much toxin remained after ozone treatment, and by testing for toxicity in cells and small organisms (Tetrahymena). The method was highly effective for 9 of 10 different toxins tested. For one toxin (fumonisin) although ozone altered the chemical structure, it did not reduce the toxicity. Ozone treatment appears to be a potentially useful method for decontamination of crops that might contain mycotoxins.
