In 2015, Life Rainbow mycotoxin analysis lab collected 248 feed samples from our farm customers in Taiwan. The survey provides essential information on the feed pollution situation of Aflatoxin, Zearalenone, Fumonisins, and DON in Taiwan. All the samples were analyzed using ELISA and the Mycotoxin analysis kit purchased from Romer’s lab.


The results show that 90% of feed was contaminated with DON; 76% of feed was contaminated with Zearalenone; 66% of feed was contaminated with Fumonisins; and 63% of feed was contaminated with Aflatoxin. 

Except for Aflatoxin, the level of Zearalenone, Fumonisins, and DON can compromise the growth performance and even danger the health status of swine and poultry (Cheng et al. 2006; Pinton et al. 2008; Prelusky et al. 1994). More than that, most of feed samples are multi-contaminated by more than 2 types of mycotoxins, which often added damage to the animals.



Averagely, more than 70% of commercial feed in Taiwan is contaminated by mycotoxins. This can be due to the dramatic weather condition in the exporting countries (ex: USA and Brazil), the shipping conditions, and the storage condition in Taiwan. It is important for pig farmers to keep this information in mind, and to take action in protecting the animals!
