Researchers at Fraunhofer, Europe’s largest application-oriented research organization, have developed a test that can detect pesticide build up in farmed fish. As demand for fish has grown, the fish meal used as fed has been replaced with soya, maize and rape which can contain pesticides.
The European commission will soon publish new rules requiring producers and importers who wish to use new pesticides to prove they do not accumulate in fish. This test will supply the information required.
