PFAS in Soup Can Linings: Safe Canned Soup Choices

PFAS, sometimes called forever chemicals, keep turning up in products that families use every day. One that catches most people off guard: the interior lining of canned soups. Small daily choices add up, and if your family eats canned soup regularly, this is worth knowing about. This guide covers what to look for, which products carry the highest risk, and the easiest swaps you can make right now.

Why PFAS in canned soup linings is a health concern

PFAS compounds have been linked to disruption of the hormone system, elevated cholesterol, immune suppression, and increased cancer risk with certain exposures. Research published by environmental health scientists has found detectable PFAS in blood samples of people with common household exposures.

Canned soup is a pantry staple in millions of homes. The interior coating that prevents metal from contacting food may contain fluorinated compounds. Hot liquids can speed up leaching, so heating soup directly in the can or microwaving in a lined container raises the potential for PFAS transfer into your food. These chemicals don’t break down easily, and every unnecessary exposure matters, especially for children and pregnant women.

How to find PFAS-free canned soup options

You can’t always tell from the label. Here are practical ways to identify cleaner products:

• Look for brands that disclose BPA-free and PFAS-free can linings. Some companies now use plant-based or ceramic-based coatings and say so on their packaging or website.
• Glass-jarred soups eliminate can-lining concerns entirely. Brands like Amy’s and Rao’s offer soup in glass jars.
• Shelf-stable cartons (Tetra Pak) are another option, though you should still check whether the brand confirms PFAS-free packaging.
• Check the PFAS Free Life Database for tested, verified products across food and beverage categories.

Safer canned soup alternatives

If you want to move away from traditional canned soups, a few options work well:

• Soups in glass jars are inert and do not leach chemicals into food
• Frozen soups bypass can linings altogether and often use simpler packaging
• Making soup at home and storing it in glass or stainless steel containers gives you the most control
• Boxed or cartoned soups from brands that confirm fluorine-free packaging are another solid choice

A useful kitchen tool for storing homemade soup safely is the Stasher Reusable Half Gallon Silicone Food Storage Bag, which is PFAS-free, freezer-safe, and dishwasher-safe.

Tips to reduce PFAS exposure from canned foods

Beyond swapping specific products, daily habits matter:

• Transfer canned soup to a glass or stainless steel pot before heating, rather than microwaving in the can or a plastic bowl
• Rinse canned vegetables and beans before cooking to reduce contact with can-lining residue
• Store leftovers in glass containers instead of leaving food in opened cans
• Filter your drinking water with a reverse osmosis system, which is the most effective household option for PFAS removal

Frequently asked questions

Do all canned soups contain PFAS?

No. But many traditional metal cans use interior coatings that may include fluorinated compounds. The safest approach is to look for brands that specifically confirm PFAS-free and BPA-free can linings, or to choose soups packaged in glass jars or cartons instead.

How do I know if my canned soup has PFAS in the lining?

Without laboratory testing, it is difficult to know for certain. Most cans use an interior coating to prevent corrosion, and some of these coatings contain fluorinated compounds. Contact the soup brand directly and ask whether their can linings are fluorine-free. You can also search the PFAS Free Life Database for verified clean products.

What health risks are linked to PFAS in canned food?

PFAS exposure from food packaging has been associated with elevated cholesterol, immune system disruption, hormone interference, and in some cases increased cancer risk. Children and pregnant women are especially vulnerable. Reducing exposure through product swaps can lower your body burden over time, since PFAS do eventually clear from the body when new exposure stops.
