At least two areas in Western Samar remain positive for the red tide threat, the Bureau of Fisheries and Aquatic Resources said.
In a June 22 update, the BFAR said Cambatutay Bay and Irong-Irong remain positive for paralytic shellfish poisoning.
The BFAR warned all types of shellfish and “alamang” from the area “are not safe for human consumption.”
Other areas remain free of the threat for now.
Also, the BFAR reminded residents not to harvest, eat, buy or sell such shellfish from the areas.
The BFAR reminded residents fish, squids, shrimps and crabs are safe provided they are fresh and washed thoroughly.
It added internal organs like gills and intestines removed before eating.
