Deoxynivalenol in grain and grain products.

• The results are intermediate data. Investigations have not yet been completed.• Grain and grain products contain different quantities of DON.• The main cause for DON infection is contamination of the grain during the growing season.• DON may also be produced during storage and/or handling and processing of food.• There does not seem to be a zero-tolerance.• It is essential to take appropriate measures during primary production and secondary production to minimize mycotoxin formation.• The results explain a possible consumer risk that has to be taken seriously.• Furthermore it is necessary to determine EC-wide limiting DON values for foodstuff.
