An extensive literature review has pointed out knowledge gaps about the migration of polyethylene terephthalate (PET) oligomers from food contact materials (FCMs) into foods, as well as inadequate risk assessment for the chemicals.

The European Food Safety Authority (EFSA) has determined the food safety of plastic polyethylene terephthalate (PET) when produced by a recycling process called Poly Recycling for use in food contact materials.
