Research output: Contribution to conferenceAbstract


In the Netherlands we investigated animal and plant products on potentially hazardous contamination with heavy metals, mycotoxins, pesticide residues, patho-genic micro-organisms and nitrate. In most cases, the organically produced foods had equal or lower amounts of contaminants than conventionally pro-duced products. These results conflict with a common idea that organic farming theoretically increases food safety risks. For many contaminants organic food showed a large diversity in the amount of contamina-tion. Experience with organic farming, managing and manure use partly explain these differences. Understanding of these cultivation parameters can help in further improvement of organic cultivation practices.
