In a press release published on July 1, 2014 the German Federal Institute for Risk Assessment (BfR) advises against barbecuing and baking of chicken on top of a beer can. The BfR states that under normal use conditions the migration of printing inks into beverages at dangerous levels is limited by a functional barrier. However, when barbecuing or baking chicken on top of beer cans, the chicken comes into direct contact with the outer printed layer of the beverage can. Further, the inner coating of the beer can may release components into the chicken. The migration of food contact substances is favored by the high temperature and fat content of the chicken. The BfR points out that the migration of food contact substances during the baking and barbecuing of chicken on beer cans has not been assessed for safety. The BfR thus states that migration of food contact substances may occur at levels harmful to health and advises against this cooking practice.
