The U.S. Food and Drug Administration (FDA) has made a significant announcement regarding the elimination of grease-proofing materials containing per- and polyfluoroalkyl substances (PFAS) from food packaging in the United States. This decision marks a pivotal step in safeguarding consumer health by addressing a major source of dietary exposure to PFAS through commonly used food packaging materials such as fast-food wrappers, microwave popcorn bags, take-out paperboard containers, and pet food bags.

PFAS comprise a diverse group of thousands of chemicals known for their resistance to grease, oil, water, and heat. While the FDA has authorized certain PFAS for limited use in cookware, food packaging, and food processing equipment, exposure to some types of PFAS has been linked to serious health effects. As part of its mission to ensure the safety of the food supply, the FDA evaluates the use of chemicals as food ingredients and substances that come into contact with food, including food packaging materials, to ensure these uses are safe for consumers.

The recent announcement by the FDA signifies the fulfillment of a voluntary commitment by manufacturers to cease the sale of food contact substances containing certain PFAS intended for use as grease-proofing agents in the United States. This collaborative effort between the FDA and industry stakeholders underscores a significant milestone in protecting U.S. consumers from potentially harmful food-contact chemicals.

The FDA's proactive approach to assessing the safety of food packaging materials involves conducting rigorous post-market safety assessments and engaging with industry stakeholders to address emerging concerns. In 2020, the FDA initiated discussions with companies to discontinue the sales of grease-proofing substances containing specific types of PFAS following comprehensive safety evaluations conducted by FDA scientists. These efforts have resulted in voluntary commitments from manufacturers to phase out the use of PFAS-containing substances in paper and paperboard food packaging products.

While assessing the progress of these initiatives may require time due to industry implementation and data reporting lags, the FDA remains encouraged by the collaborative efforts aimed at promoting public health and welfare. The commitment of both regulatory agencies and industry partners to prioritize consumer safety underscores the potential for positive health outcomes through collaborative action.
