European canned tuna shows high mercury contamination

A study by the French organization Bloom, published on Noklapja, analyzed 148 canned tuna samples purchased from markets across Europe. Laboratory tests found mercury in every product, with 57 % exceeding the strict safety limit of 0.3 mg per kilogram set for fish. Many cans also surpassed the European Union’s legal limit of 1 mg/kg. The highest level, 3.9 mg/kg, was recorded in a "Petit Navire" brand can bought at a Carrefour City store in Paris, a concentration roughly four times the EU maximum. Several French brands also breached the legal threshold. Experts explained that larger, older predatory fish accumulate more heavy metals, making tuna a particular risk for mercury exposure.

The findings suggest that current EU limits may not adequately protect consumers, prompting calls for stricter regulations and more rigorous testing of seafood products.
