No more red tide warning in parts of Misamis Occidental, Davao Oriental

THE BUREAU of Fisheries and Aquatic Resources (BFAR) has lifted red tide warnings in the areas of Murcielagos Bay (Sapang Dalaga and Baliangao) in Misamis Occidental and Balite Bay in Davao Oriental after testing negative for paralytic shellfish poison or more commonly referred to as red tide.

In its 24th shellfish bulletin, BFAR also raised new warnings in the areas of Carigara Bay in Leyte and Biliran Islands after testing positive for red tide contamination.

Meanwhile, areas that remain affected by red tide include Milagros in Masbate; Dauis and Tagbilaran City in Bohol; San Pedro Bay in Western Samar; Matarinao Bay in Eastern Samar; Dumanquillas Bay in Zamboanga del Sur; Murcielagos Bay in Zamboanga del Norte; and Lianga Bay in Surigao del Sur.

All types of shellfish and Acetes sp. or alamang harvested in areas affected by red tide are unfit for human consumption. Other marine species sourced from the same areas can still be consumed with proper handling.

Red tide occurs due to high concentrations of algae in the water. Human consumption of contaminated shellfish may result in paralytic shellfish poisoning, which affects the nervous system.

Typical symptoms of paralytic shellfish poisoning include headache, dizziness, and nausea. Severe cases may cause muscular paralysis and respiratory problems. — Revin Mikhael D. Ochave
