TACLOBAN CITY – Red tide bloom has expanded in Eastern Samar as the phenomenon remains in five other bays in Eastern Visayas region, the Bureau of Fisheries and Aquatic Resources (BFAR) reported on Tuesday.
BFAR said red tide has again bloomed in the coastal waters of Guiuan in Eastern Samar, which is adjacent to Matarinao Bay, which recorded a recurrence of the toxic microorganism last week.
In an issued bulletin, the BFAR regional office here said seawater samples collected along the coastal waters of Guiuan are again positive for red tide that causes paralytic shellfish poison (PSP).
“Hence, we are issuing this precautionary advice to the public to refrain from gathering, selling, and eating all types of shellfish and Acetes sp. locally known as ‘alamang or hipon’ from the said bay,” the BFAR said in its latest advisory.
On June 21, Matarinao Bay in the towns of General MacArthur, Hernani, Quinapondan, and Salcedo in Eastern Samar was included in the red tide-hit areas.
Red tide also remains in Irong-irong Bay in Catbalogan, Samar; Cambatutay Bay in Tarangnan, Samar; coastal waters of Calubian, Leyte; and coastal waters of Daram, Samar.
Fish, squid, crab, and shrimp gathered from these areas are safe to eat provided that all entrails are removed and washed thoroughly with running water before cooking.
The fisheries bureau reiterated its call to local government units to heighten their watch against gathering, trading, and consumption of shellfish to prevent the incidence of PSP.
PSP occurs from ingesting bivalve shellfish (such as mussels, oysters, and clams) that contain red tide toxins.
Red tide is a term used to describe a phenomenon where the water is discolored by high algal biomass or the concentration of algae.
