FDA Seeks Information on Potential PFAS-Contaminated Containers

Information on certain plastic food storage containers that may transfer PFAS onto food is being sought by the Food and Drug Administration through a request for information issued Tuesday.

Manufacturers apply fluorine gas to polyethylene plastic containers to strengthen them, the FDA said. But fluorinating the plastic can create per- and polyfluoroalkyl substances (PFAS).

The FDA is requesting scientific data and information on uses of fluorinated polyethylene that contact food, as well as consumer dietary exposure, and safety information on substances that may leach from food containers. “FDA may use information submitted in response to this notice to update dietary exposure estimates and safety assessments for the authorized food contact use of fluorinated polyethylene,” the notice said.

• Environmental Protection Agency tests have found leached PFAS from heavy plastic, or “high-density polyethylene,” containers into mosquito control products.
• EPA detailed steps asking pesticide, plastics, and other industries to address the possibility that PFAS can transfer from container linings into the products they hold.
• In conjunction with EPA’s past testing, the FDA issued a letter reminding the responsibility of the manufacturer of a Food Contact Substance to ensure that food contact materials comply with the specifications and limitations.
