PFAS in Canned Food Linings: Hidden Exposure in the Pantry

PFAS are called “forever chemicals” because they don’t break down in the environment or the human body. For decades, manufacturers used PFAS-based coatings on food cans to provide water resistance and non-stick performance. This guide cuts through the marketing claims so you can choose safer options for your family.

Why PFAS in canned food is a health concern

PFAS has been linked to hormone disruption, elevated cholesterol, immune suppression, and in some cases increased cancer risk. Research from environmental health scientists has found PFAS in the blood of people with common household exposures. Since these chemicals don’t break down in your body, reducing unnecessary exposure matters, especially for children and pregnant women.

How to identify PFAS-free canned food products

Reading labels isn’t always enough — manufacturers aren’t required to disclose PFAS use on consumer products in most U.S. states. Here’s what to look for:

• Certifications: OEKO-TEX Standard 100, bluesign, and GOTS certification prohibit PFAS in certified products.
• Avoid key terms: “Water-resistant,” “stain-resistant,” “wrinkle-free,” or “grease-proof” on non-food products often signal DWR or PFAS-based treatments.
• Contact brands directly: Ask whether their products use fluorinated treatments or coatings. Reputable brands will answer clearly.
• Check the PFAS Free Life Database for tested, verified products across hundreds of categories.

Safer alternatives for canned food

When switching away from PFAS-containing products, look for:

• Stainless steel or glass containers, which are naturally PFAS-free
• Products with OEKO-TEX certification, which prohibits PFAS
• Brands that publish their chemical policies (like Patagonia and Cotopaxi)
• Certified organic options that exclude synthetic treatments

One trusted product to consider: GreenPan Lima Ceramic Non-Stick 10-Inch Fry Pan, which offers a PFAS-free alternative you can order today.

Ways to reduce PFAS exposure at home

Beyond the products you buy, your daily habits matter:

• Ventilate your home regularly. PFAS can off-gas from products and settle into household dust, which children inhale.
• Wash new items before using them. This reduces surface chemical buildup.
• Choose food-grade materials for anything that touches food or skin.
• Filter your drinking water. A reverse osmosis system is the most effective household option for PFAS removal.

Frequently Asked Questions

Do all food products contain PFAS?

No, not all food products contain PFAS. However, many products that are marketed as water-resistant, stain-resistant, or non-stick have historically used PFAS-based treatments. The safest approach is to look for third-party certifications like OEKO-TEX Standard 100 or to contact the manufacturer directly to ask about their chemical policy.

Can I test my home for PFAS contamination?

Yes. You can test your drinking water for PFAS using certified laboratory testing services or at-home kits from companies like SimpleLab. For other types of exposure — from products or household dust — testing is more complex, but starting with your water is the most impactful first step. Your state health department may also offer resources or low-cost testing programs.

Are PFAS-free food alternatives effective?

Yes, PFAS-free alternatives have improved significantly in recent years. Natural materials like stainless steel, cast iron, glass, and untreated natural fibers perform well without any chemical coatings. For water-resistant textiles, fluorine-free DWR treatments have become widely available and work well for everyday conditions. Many families find the alternatives work just as well once they make the switch.
