SWAKOPMUND, 12 JAN (NAMPA) – The Ministry of Fisheries and Marine Resources has warned the public against the consumption of mussels and oysters due to the recent detection of the Diarrhetic Shellfish Poison (DSP).
DSP is one of the four recognised symptom types of shellfish poisoning, with the others being paralytic, neurotoxic and amnesic shellfish poison.
A media statement issued by the Ministry’s Permanent Secretary, Ueritjiua Kauaria, on Friday stated that the oyster and mussel samples from Walvis Bay Aquaculture Production Area 1 that were submitted for testing indicated the presence of DPS at a level higher than the permissible level in these samples and therefore declared unsafe for consumption until further notice.
“The shellfish have been tested for biotoxins during the most recent official sampling and testing facilitated by the Namibia Standards Institutions (NSI) as part of the National Shellfish Sanitation Programme,” Kauaria said.
Furthermore, members of the public have also been cautioned that marine biotoxins cannot be destroyed by cooking or freezing.
The DPS symptoms include nausea, vomiting , severe abdominal pains and diarrhea. The ministry has advised seeking immediate medical attention when any of the mentioned symptoms occur after the consumption of oysters or mussels.
No life-threatening symptoms or fatalities have thus far been recorded owing to DSP, the statement added.
