The advisory, released on November 27, 2024, warns against shellfish, particularly Alamang or Hipon, from the affected area to prevent poisoning caused by red tide.
“To safeguard human lives, this advisory is issued as a precautionary measure to the public to refrain from gathering, selling, and eating all types of shellfishes and Acetes sp. Locally known as “Alamang or Hipon” from Balite Bay in Mati City, Davao Oriental to avoid possible poisoning,” the office said.
Laboratory tests from BFAR-Davao’s Regional Fisheries Integrated Laboratory confirmed that seawater samples from Balite Bay tested positive for Pyrodinium bahamense, a dinoflagellate that produces saxitoxin, the toxin responsible for PSP.
PSP is a foodborne illness that can cause gastrointestinal distress and neurological symptoms in those who consume contaminated shellfish. Currently, there is no antidote for saxitoxin, and treatment is supportive.
However, fish, squid, crab, and shrimp are safe to consume, provided they are fresh, their entrails are removed, and the meat is properly washed before cooking.
Bfar-Davao is monitoring the area to protect public health and has urged Local Government Units (LGUs) to prioritize community safety in line with the Local Government Code of 1991 (RA 7160).
Red tide occurs when algae concentrations in coastal waters rise, leading to harmful effects on both humans and the environment. RGP
