BFAR 11 WARNS OF RED TIDE IN DAVOR, DAVAO OCCIDENTAL
DAVAO CITY– The regional office of the Bureau of Fisheries and Aquatic Resources (BFAR 11) warned consumers that Balite Bay in Davao Oriental and Coastal waters of Santa Maria in Davao Occidental are now positive for red tide toxins.
Based on the red tide monitoring activities of BFAR and Local Government Units (LGUs) shellfish samples collected from Balite Bay, Mati City in Davao Oriental are now positive for the red tide toxin and to avoid Paralytic Shellfish Poisoning (PSP) the public is advised to refrain from eating, gathering or harvesting, transporting and marketing shellfish from Balite Bay until such time that the shellfish toxicity level has gone down below the regulatory limit.
All types of shellfish or alamang gathered from the areas mentioned are not safe for human consumption while fish, squids, shrimps and crabs are safe for human consumption provided that they are fresh and washed thoroughly and internal organs such as gills and intestines are removed before cooking.
The most common human health problems associated with red tides and other harmful algae blooms are various types of gastrointestinal, respiratory, and neurological disorders. The natural toxins in harmful algae can cause a variety of illnesses.
The coastal waters of Sta. Maria in Davao Occidental positive for paralytic shellfish poison (PSP).
Maria Loida M. Avorque, BFAR 11 senior aquaculturist and head of chemistry laboratory said the El Nino phenomenon has something to do with the presence of red tide toxins because of high temperature during dry spell.
“Leaching out of nutrients from upland goes to the ocean. These toxins due to algal bloom,” Avorque said.
Moreover, based on the Shellfish Bulletin No. 07 Series of 2019, the latest laboratory results of the BFAR and Local Government Units (LGUs), shellfishes at San Pedro Bay in Western Samar, Lianga Bay in Surigao del Sur; and ckastal waters of Dauis and Tagbilaran City in Bohol are still positive for paralytic shellfish poison that is beyond the regulatory limit.
