Deoxynivalenol (DON) is one of the most common mycotoxins in Asia. According to the 2014 BIOMIN Mycotoxin Survey, 65% of 1,762 tested samples from Asia were contaminated by DON, with an average of positive level of 512 ppb. Contaminated feed ingested by animals leads to mycotoxin exposure and impaired health effects.

Production losses due to mycotoxin contamination are clearly subject to a number of factors and uncertainties. The losses are hugely variable in time and difficult to estimate. However, the effects of the contamination are often significant and can be long-lasting.
The economic impact of mycotoxins is difficult to estimate even after an outbreak of mycotoxicosis. The most important losses are probably those associated with long-term under-performance. Estimates of this can be made on the basis of the information provided earlier. A simple simulation model was developed that allows for the estimation of production and financial losses due to the long-term sub-clinical impact of mycotoxins in dairy cattle.
As our weapons in the fight against mycotoxins become more sophisticated, so must the methods we use to test their efficacy. Simulating intestinal conditions and "stress gene" technology are very helpful but sometimes no longer the best or fast approach to help to develop more effective elimination strategies. Recently Impextraco developed a wide range of in vivo protocols to determine the effect of mycotoxins in an early stage, using biomarkers.
