In 2016, Life Rainbow mycotoxin analysis laboratory collected 417 feed samples from feed mills of large and medium size in Taiwan. The survey reveals essential information on the pollution degree of major mycotoxins including aflatoxins, zearalenone, fumonisins and DON in poultry and swine feed. All the samples were analyzed using ELISA and the mycotoxin analysis kit from Romer’s lab.
The results show that 92% of feed were contaminated with DON; 86% of feed were contaminated with zearalenone, 77% of feed were contaminated with aflatoxins; and 53% of feed were contaminated with fumonisins.

Comparing to the same survey in 2015, the pollution percentage increased in DON (from 89.5% to 91.8%), zearalenone (from 76.2% to 85.8%), and aflatoxins (from 62.5% to 76.8%). The average concentration increased by more than 10% (see Table 2).

Comparing to the Asian regional result from a global survey (World mycotoxin survey 2016, Biomin) the similar trend in DON, zearalenone, and aflatoxins is observed. Meanwhile, the fumonisins concentration and pollution percentage are found to be lower in the Taiwanese feed samples.
Mycotoxin remains to be a significant issue in feed supply chain. A high incidence of single and multiple types of mycotoxin contamination is observed in feed. The risk is unpredictable while only comparatively small amount of feed were sampled and tested in the laboratory. Moreover, the mycotoxin pollution is expected to become worse in the coming years due to the extreme weather condition. Therefore, it is essential for feed producers to stay alert and take action to control mycotoxin risk.
