  The occurrence of zearalenone and the metabolites (zearalanone, zearalenols and zearalanols) in feeds distributed in Japan from fiscal years 2014 to 2019 was investigated using the official analytical method validated by the interlaboratory study. As a result of investigating on 121 samples of corn, 62 samples of soybean meal and 205 samples of formula feed, zearalenone was detected in over 90 % of the samples. Zearalanols were not detected in any samples. Among the zearalenone metabolites, β-zearalenol was detected at the highest rate. Furthermore, it was suggested that the proportion of the zearalenone metabolites differed depending on the type of raw material.
