The Kuala Lumpur Fisheries Biosecurity Centre’s laboratory analysis has found harmful algae in the waters of Port Dickson, contaminating mussels and making them unsafe to eat. The Department of Fisheries (DOF) deputy director-general mentioned that the water samples and mussels had been contaminated with biotoxins as well as harmful algae species such as Prorocentrum, Alexandrium, and Pseudonitzschia. The hot weather has caused these algae to multiply quickly in the waters, affecting mussels but not other marine life like fish, shrimp, and crabs. The public has been advised not to consume these mussels for at least 20 days, and further testing will be done after the festive season to ensure safety.
DOF will continue monitoring and testing the water according to established procedures until the algae cell density decreases and biotoxins are no longer found in the mussel contents. The department is working with other enforcement agencies such as the Royal Malaysian Police and marine police to prevent the harvesting and sale of shellfish in the area. There are 40 registered mussel operators in Pasir Panjang in Port Dickson, along with unregistered ones, but existing mussels in the waters will neutralize themselves over time. However, any mussels that have been harvested and sold must be destroyed to prevent further contamination.
Water samples taken in waters off Melaka and Johor have been found to be safe with no algae proliferation, indicating that the issue is localized to the Port Dickson area. One poisoning victim is still receiving treatment in the ICU at Port Dickson Hospital, underscoring the seriousness of the contamination. The Negri Sembilan DOF had initiated sampling of mussels and water in response to reports of food poisoning from seafood consumption. The state Health Department reported eight cases of food poisoning linked to mussel consumption, with two cases requiring ICU treatment, five in regular wards, and one outpatient case.
Efforts are underway to ensure the safety of seafood in Port Dickson, with continued testing and monitoring of the waters. The DOF and other enforcement agencies are collaborating to prevent further contamination and safeguard public health. The situation is being closely monitored, with plans to conduct additional testing after the festive season to determine when mussels can be safely consumed again. Public awareness of the issue is being raised to prevent further cases of food poisoning and ensure the safety of seafood consumers in the area.
