On August 28, 2014 the German Federal Institute for Risk Assessment (BfR) published a FAQ recommending that the maximum permissible migration value for primary aromatic amines (PAA) in printing ink used for paper napkins and food packaging is re-evaluated. Some PAAs are classified as known or potential human carcinogens. In the FAQ, the BfR states that consumer exposure to PAAs should be limited to the greatest possible extent. The BfR further recommends consumers to avoid long term storage of food in printed paper packaging and to refrain from wrapping food in printed napkins.
