Red tide ban still up: fisheries bureau
THE latest laboratory analysis of the Bureau of Fisheries and Aquatic Resources and local government units showed certain areas in Zamboanga del Sur, Davao Oriental, and Surigao del del Sur are still positive for Red Tide Toxin (PSP Toxins) and Toxic Red Tide organisms.
Still under shellfish ban due to red tide toxin are the coastal waters of Dumaguillas Bay in Zamboanga del Sur, Balite Bay in Mati, Davao Oriental, and Bislig Bay in Bislig City, Surigao del Sur.
Regional Fish Health Officer Madilyn T. Navarce said the red tide organism is dormant in the coastal waters, however due to pollution, siltation and other form of water disturbances can increase its level.
The Municipality of Mati, Davao Oriental, had already implemented the Shellfish Ban since year 2000 particularly Balite Bay in Mati, Davao Oriental. The ordinance prohibits the harvesting of bivalves shells (Tahong) in their area.
Navarce said the bivalve products and "tahong" sold in Davao City market are coming from the provinces, which are not affected by the red tide.
The Philippines has adopted a red tide standard to a maximum tolerable level of 40 micro gram/100 grams of shell-meat. This is far below from the World Health Organization standard that is set to a maximum tolerable level of 80 micro gram/100 gram of shell meat.
Navarce said the standard is at the safest level, because there are cases found and documented by the fisheries bureau that above 40 micro grams/100 grams of shell meat might inflict Paralytic Shellfish Poisoning to human being.
She also added that the bureau is strictly monitoring the transport of shell-meat entering Davao City. It requires the issuance of the health certificate from its origin before it can be transported to any place. (PIA/ADCahilog)
