A new report from the Food Packaging Forum identifies 175 potentially hazardous substances used legally in food contact materials. According to the report, many of these substances – chemicals used in food packaging or to produce those materials – are classified as carcinogenic, mutagenic or reprotoxic. Others are endocrine disrupters, and some are persistent and bioaccumulative. Most of these materials are plastics, highlighting the need for measuring chemicals of concern in plastics, especially when those plastics are intended to keep food safe and fresh.
