Table 2 gives the known effects of the mycotoxins listed in Table 1. Not all are cancer-causing. Aflatoxin is indeed a potent carcinogen, but the immediate effects of the Fusarium toxins are often more striking. Most of the economic impacts are on animal health. Swine are the food animal species most at risk from these mycotoxins, that usually are found in corn.
Horses are extremely sensitive to fumonisins.
Vomitoxin causes a dose related reduced feed intake in swine at levels above 1 ppm in the ration. If clean feed is offered, feed consumption resumes within 24 hours or less. There are no documented reproductive effects of vomitoxin in swine. Cattle have consumed up to 10 ppm vomitoxin with no adverse effects. Zearalenone is an estrogenic mycotoxin that occurs in corn and wheat in the midwest.
