Are there rules to protect consumers?
Yes. The European Framework Regulation (EC) No. 1935/2004 on Materials and Articles Intended to come into Contact with Foodstuffs lays down the general safety requirements for all materials and articles. These regulations require that materials and articles containing BPA, such as some can coatings, do not make food harmful. The regulations also make sure that they do not change the nature, substance or quality of the food.
The Plastic Materials and Articles in Contact with Food (England) Regulations 2009 permit the use of BPA in the manufacture of plastic materials and articles intended to come into contact with food, provided that no more than 0.6 mg/kg migrates into the food.
