Are PFAS in fast food wrappers and takeout containers safe?

What's on that wrapper

Fast food wrappers, burger boxes, french fry containers, and takeout bags are often treated with PFAS (per- and polyfluoroalkyl substances) to make them grease-resistant. These are the same "forever chemicals" found in nonstick pans and waterproof clothing. When hot, greasy food sits in these containers, PFAS can migrate into your meal.

PFAS don't break down in the environment or in your body. They accumulate over time, which means every fast food meal adds to your total exposure.

What the research says

A 2026 study tested food contact materials and found PFAS compounds actively migrating from packaging into food, especially when the food was hot or greasy. The warmer and fattier the food, the more chemicals transferred.

A second 2026 study confirmed that PFAS from food packaging is one of the primary routes of human exposure. The research found these chemicals in blood samples at levels linked to immune system disruption and hormonal changes.

A third 2026 analysis showed that even packaging marketed as "compostable" or "eco-friendly" can contain PFAS treatments, meaning switching to green takeout containers doesn't necessarily reduce your exposure.

How to reduce your exposure

Take food out of the wrapper or box before eating. Transfer takeout into glass or ceramic dishes at home. When possible, skip the drive-through and cook with fresh ingredients. If you eat fast food regularly, these small steps add up over time.
