Avoid PFAS this summer - A scientist’s tips for smarter choices

What is PFAS and why should I care?

"PFAS (per- and polyfluoroalkyl substances) are a large group of chemicals used to repel grease, dirt, and water. They’re found in everything from frying pans and rain jackets to food packaging," says Philipp Wanner. The problem is that PFAS degrade extremely slowly in both the environment and our bodies, which is why they're sometimes called ‘forever chemicals."

"It’s not about panicking, but there are good reasons to reduce your exposure, as PFAS have been linked to several health risks with long-term and high exposure."

How can PFAS end up in the food we eat during summer?

"Some grilling accessories may be treated with PFAS to withstand fat and heat, such as non-stick foil, grill sheets, fire starters, or disposable grill grates. At high temperatures, there’s a risk that PFAS may transfer to the food, especially if the surface is damaged. PFAS can also be found in grease-resistant food packaging, such as some pizza boxes or burger wrappers, and in fish from contaminated waters."

Can PFAS be found in what I drink - like beer, wine or water?

"Low levels of PFAS can occur in some beverages, depending on where and how they were produced. Drinks made with water from PFAS-contaminated sources may contain traces. Generally, the levels are low but there’s no reason to choose bottled water if your tap water is regularly tested and of good quality."

How do I know if a product contains PFAS?

"Unfortunately, it’s not always clear. Sometimes it's listed in the ingredients, so look for terms like PTFE, fluoro-, or perfluoro-. Also look for products with environmental labels, such as the Nordic Swan Ecolabel or the EU Ecolabel, which rarely contain PFAS."
