On 11 August, the environmental protection service of the Spanish civil guard SEPRONA announced the seizure of 45 tons of illegally treated tuna fish. Four people were investigated and face possible criminal penalties of up to four years in prison for endangering public health, as well as administrative sanctions. The investigation has so far uncovered three companies and three fishing vessels involved in the fraudulent scheme.
Investigators found that frozen tuna only suitable for canning had been illegally treated with substances that enhance the colour and then been diverted to the market to be sold as fresh fish. This treatment can pose a serious public health risk associated with allergic reactions to histamine.
The investigation was coordinated by EUROPOL under the OPSON VII operation, in collaboration with the European Commission and other Member States, which was previously reported on the Food Authenticity Network in May 2018.
Criminal investigations are ongoing.
