Bangkok: The Department of Fisheries has confirmed that recent tests on canned fish products were conducted in line with international standards. They noted that discrepancies in results could arise from samples originating from different production batches.
According to Thai News Agency, the Department emphasized that these tests adhered to scientific principles and international protocols. They also highlighted that the traceability of raw materials and food standards oversight falls under the Food and Drug Administration (FDA). Ms. Thitiporn Hlaoprasert, Director-General of the Department of Fisheries, addressed public concerns over the identification of aquatic species in canned fish products. She assured that the testing followed international laboratory standards, employing morphological identification and taxonomy principles. These methods are consistent with those used for export inspections, which have been validated by trading partners such as the European Union, the United States, and the Republic of Korea.
The Director-General revealed that on May 5, 2026, the department received three samples from the FDA, which were examined and returned by May 6, 2026. The analysis showed that the Bonus brand mackerel in tomato sauce contained sardines, while the other two unlabeled samples were identified as tilapia. She explained that differentiating between tilapia and black-chinned gourami relies on specific taxonomic differences. While DNA sequencing is another method, it is more complex and costly. The Director-General also stressed that differences in test results from other agencies could be due to variations in the production batch or can, since factories might utilize raw materials from multiple sources, and environmental factors could influence classification outcomes.
The responsibility for food quality control and raw material traceability lies with the FDA, as stipulated under the Food Act B.E. 2522 (1979). The Department of Fisheries continues to tackle the black-chinned tilapia infestation through measures such as controlling its spread, promoting diverse uses for the fish, and fostering collaboration across sectors for effective management and resolution.
