A red tide alert was raised over Puerto Princesa Bay by the Bureau of Fisheries and Aquatic Resources (BFAR) on Wednesday.
In its Shellfish Bulletin No. 13, dated July 24, BFAR said shellfish and Acetes sp. or alamang collected from the bay are not safe for human consumption.
BFAR stated in an advisory that based on the results of their red tide monitoring with the city government, shellfish samples collected from Puerto Princesa Bay are now positive for the red tide toxin.
However, fish, squid, shrimps and crabs are safe for human consumption as long as they are fresh and washed thoroughly before cooking.
Internal organs such as gills and intestines must also be removed before cooking.
