BFAR raises red tide alert in Misamis Oriental after harmful algal bloom

The Bureau of Fisheries and Aquatic Resources (BFAR) in Northern Mindanao has raised a red tide alert in Barangay Casinglot, Tagoloan, Misamis Oriental, due to a harmful algal bloom.

The discoloration of seawater observed on September 9, 2025, was identified as being caused by Heterosigma akashiwo, a type of plankton that causes red tide.

The BFAR reported that paralytic shellfish poison (PSP) levels in several areas exceeded regulatory limits.

The public is strongly advised to refrain from eating dead fish from the affected area and to ensure that all seafood consumed is thoroughly cleaned and cooked.

Additionally, people are urged to avoid swimming in the discolored waters to prevent potential health risks associated with red tide toxins.
