Test Description

This proficiency test is for the identification and quantification of mycotoxins in wheat flour, including the masked mycotoxin DON-3-Glc. So called masked mycotoxins are produced as a plant defence mechanism, bio-transforming the mycotoxin into a less toxic form. However, the modified mycotoxin may be hydrolysed during digestion, releasing the more toxic parent compound.

Mycotoxins are toxic secondary metabolites produced by fungi on agricultural commodities in the field or during storage.  It is estimated at 25% of the world's food crops are affected, resulting in large commercial losses. Mycotoxins can cause serious health problems, including some being suspected carcinogens, and so are tightly regulated across the world. Mycotoxin contamination is the largest cause of rapid alerts raised against imported food products.  Fapas has introduced multi-mycotoxin proficiency tests as well as those for emerging mycotoxins.

Fapas proficiency tests highlight potential deficiencies within your testing process, such as highlighting any unconscious bias, through ineffective instrumentation calibration for example. By using real feed matrices your proficiency test results are immediately comparable to your routine analysis and as such can provide direct improvements from which to safeguard your high-quality testing practices.
