The Bureau of Fisheries and Aquatic Resources (BFAR) in Eastern Visayas has issued a red tide warning over Cancabato Bay in Tacloban City after seawater samples tested positive for Pyrodinium bahamense, a toxin-producing microorganism responsible for paralytic shellfish poisoning (PSP). BFAR, in an Aug. 10 advisory, said filtered seawater samples from the bay confirmed the presence of saxitoxin, the dangerous substance associated with red tide events.
