Canned food and beverages — food safety profile
Low riskMetal cans — primarily steel (tinplate) or aluminum — used to package shelf-stable foods including soups, beans, tomatoes, fish, vegetables, fruit, and beverages.
What is this product?
Metal cans — primarily steel (tinplate) or aluminum — used to package shelf-stable foods including soups, beans, tomatoes, fish, vegetables, fruit, and beverages. The interior of the can is coated with a lacquer or polymer lining to prevent corrosion and metal taste. Historically, the dominant lining material was BPA-based epoxy resin. Industry has progressively replaced BPA linings, but alternatives including BPS- and BPF-based linings may present similar endocrine concerns.

Compounds of concern
Base ingredients
Who's most at risk
- Pregnant Women — Fetal exposure via placental transfer; developing endocrine systems of fetus
- Children — Higher food-to-body-weight ratio, developing organ systems
How to use it more safely
- Check expiration date before consumption
- Inspect can for dents, leaks, or swelling before opening
- Refrigerate after opening and consume within recommended timeframe
- Follow heating instructions if product requires preparation
Red flags — when to walk away
- Canned tomatoes, tomato sauce, tomato paste — Highly acidic food in prolonged contact with BPA can lining — among the highest BPA migration scenarios. Studies have measured BPA in commercial canned tomatoes at 10–50 ppb.
- Heating food in the can — Elevated temperature dramatically increases BPA migration from epoxy lining into food.
- 'BPA-free' label without specifying the replacement — BPS and BPF alternatives have comparable estrogenic activity to BPA in some assays. 'BPA-free' is not equivalent to 'endocrine-disruptor free.'
- Dented or damaged cans — Physical damage to the lining can create areas of direct metal-to-food contact or compromise the integrity of the polymer lining.
Green flags — what to look for
- Glass jar packaging — No BPA or BPA alternative lining in contact with food.
- Eden Organics BPA-free with oleoresin lining — Eden has used oleoresin (plant-based resin) can linings for beans since 1999 — one of the earliest documented transitions to a non-BPA lining.
Safer alternatives
- Fresh produce — No preservatives; retains more nutrients and has no expiration concerns
- Frozen fruits and vegetables — Minimal processing; comparable nutrition to fresh with longer shelf life
