Metals and PFAS linked to serious health issues are among compounds found, highlighting need for further scrutiny

More than 3,600 chemicals approved for food contact in packaging, kitchenware or food processing equipment have been found in humans, new peer-reviewed research has found, highlighting a little-regulated exposure risk to toxic substances.

The chemicals have been found in human blood, hair or breast milk. Among them are compounds known to be highly toxic, like PFAS, bisphenol, metals, phthalates and volatile organic compounds. Many are linked to cancer, hormone disruption and other serious health issues.

But many others are substances for which there are very limited public toxicological profiles, such as synthetic antioxidants used as preservatives and oligomers that stabilize ink on packaging. The study’s authors say the knowledge gaps highlight the need for further scrutiny of food contact chemicals.
