The current state of contamination and regulation of mycotoxins in feed in Japan

Abstract

Regulations of mycotoxins has been established for aflatoxinB₁, zearalenone and deoxynivalenol in feed in Japan. We conducted analysis of mycotoxins in feed in accordance with the official methods of feed analysis in Japan. As for the contamination rates of aflatoxinB₁ in maize and formula feed, the differences for every year were observed. Meanwhile, as for feed ingredients, aflatoxins were detected in what were mainly imported from Southeast Asia. In addition, we have surveyed contamination of feed ingredients and formula feeds by other mycotoxins such as ochratoxinA, deoxynivalenol, nivalenol, zearalenone and fumonisinB1.
