Testfakta finds BPA in all canned tuna samples, BPF in most
A laboratory test by Testfakta detected bisphenol A in every one of eleven canned tuna products and the substitute BPF in nine, while heavy-metal levels remained below EU limits.
Testfakta analysed eleven common canned tuna varieties and discovered that bisphenol A (BPA) was present in all of them, with the alternative chemical BPF found in nine samples. Levels of mercury, cadmium and lead stayed under the thresholds set by the European Union. The EU plans to ban BPA in food-contact materials, including fish cans, starting in January 2028. The study also noted an increase in MSC-certified products compared with a decade ago, but only one item met WWF Fish Guide standards.
Why it matters
Consumers may be exposed to endocrine-disrupting chemicals in everyday canned tuna before the EU ban takes effect.
