摘要

Potato tubers artificially infected withF. sambucinum were contaminated with diacetoxyscirpenol in concentrations up to 200 μ/tuber. The toxin could also be found in tubers without any disease symptoms. The duration of storage and an increased temperature raised toxin production in infected tubers. Susceptibility of potato cultivars towardsF. sambucinum was well correlated with toxin levels. The concentration of diacetoxyscirpenol in the susceptible cultivar was five times higher compared to the more resistant one. The toxin could not only be found in rotten tuber tissue but also in distant healthy looking parts. There is a gradient in toxin concentrations showing a strong decline with an increasing distance from the infection point. Tissue being 10–15 mm far from the diseased area contained up to 110 μg/kg. Consumers should pay attention to the fact that cutting out the diseased tissue may be not sufficient enough to prevent the intake of mycotoxins.
