WALVIS BAY, 05 APR (NAMPA) – The Ministry of Fisheries and Marine Resources has announced on Thursday that oysters in the Walvis Bay Aquaculture Production Area 1 are now safe for consumption.
This, according to the ministry’s Executive Director Moses Maurihungirire, in a media release, comes over a week after tests done on the marine products in that area tested positive for Diarrhetic Shellfish Poisoning (DSP), and was declared unsafe to consume.
“Oyster samples from the Walvis Bay Aquaculture Production Area 1 were collected and submitted for testing for DSP during the recent official sampling and testing by the Namibian Standards Institution (NSI),” he said.
He added that two consecutive tests produced negative results and oysters may therefore be harvested for direct human consumption.
Maurihungirire however cautioned that mussels from this production area still tested positive for DSP according to latest test results by the NSI.
“The tests indicated that the presence of DSP in the samples is still above the maximum permissible levels and therefore this production area remains closed for the harvesting of mussels for human consumption,” the executive director noted.
On his part, Namoyster Farm manager Theunis Keulder told a media briefing here on Thursday that in cases where oyster samples in the Walvis Bay Aquaculture Production Area 1 test positive for DSP, the farm always ensures to keep enough stock in storage on land in order to supply the local market.
“We make sure to submit oyster samples to the NSI, who conducts monthly tests to ascertain that levels of heavy metals, cadmium and other marine toxins are at acceptable levels,” Keulder stated.
