A spokesman for the centre said that the above tuna sample was taken for testing at the import level, and the results showed that the malachite green content in the sample was 1.4 parts per billion. The centre has informed the importer involved of the violation and is tracing the source and distribution of the product.
The authorities pointed out that malachite green is an industrial dye used to treat fish diseases. Currently, many countries have banned the use of malachite green in food animals.
