In 2020, the Belgian Federal Agency for the Safety of the Food Chain (FASFC) seized nearly 80 tons of tuna due to various non-compliances, including the banned use of carbon monoxide treatment. The majority of the non-compliant tuna was imported from Asia. Tests revealed issues with nitrite or nitrate levels, ascorbic acid, and histamine levels were satisfactory. The agency's operations aim to address fish fraud techniques, including the use of dyes, nitrites, nitrates, and carbon monoxide treatment, which were found in over half of the samples. The FASFC's actions are part of a broader effort to address a wider issue of food fraud in the European Union, with a focus on tuna imports from non-EU countries.
