Mould toxins

Mycotoxins are poisonous compounds generated by particular moulds. Typically, Fusarium moulds produce trichothecenes and zearalenone whereas Penicillium and Aspergillus moulds produce ochratoxin A.

Generally, feed grains and manufactured feeds are being analyzed for mycotoxins. Evira together with Customs Laboratory serve as national reference laboratory for mycotoxins. Evira also contributes to a number of national and international projects for studying mycotoxins.

Residues of pesticides, and PCB

Evira systematically monitors environmental toxins accumulated in feeds. Monitoring prevents contaminated feeds from reaching animals and harmful chemicals from reaching food.
