 This study examined the presence of four common mycotoxins, aflatoxins, afla, xerolinone, zn, deoxynivalenol, don, and fumonisins, fum, in corn, soybeans, wheat, and DDGS from 2009 to 2011. The results showed that afla, zn, don, and fum were found in 33%, 45%, 59%, and 64% of samples, respectively. Additionally, 81% of all samples tested positive for at least one mycotoxin. This study also revealed regional differences in mycotoxin levels, with higher levels of afla and don detected in samples from North America compared to those from Europe or Asia.
