Three coastal waters in the country are now free from toxic red tide but the Bureau of Fisheries and Aquatic Resources (BFAR) the problem still persists in three other areas.
The coastal waters of Milagros in Masbate; Carigara Bay in Leyte; and Murcielagos Bay in Zamboanga del Norte are now free of paralytic shellfish poison (PSP) or toxic red tide, the agency said.
However, coastal waters off Dauis and Tagbilaran City in Bohol; Dumanquillas Bay in Zamboanga del Sur; and Lianga Bay in Surigao del Sur remain positive for the toxic red tide.
According to the latest laboratory results of BFAR and concerned local government units (LGUs), shellfishes collected from the affected coastal waters were found with toxic red tide that is "beyond the regulatory limit."
All types of shellfish and alamang gathered from affected areas are "not safe for human consumption," BFAR said.
Fish, squids, shrimps, and crabs, however, are safe for human consumption provided that they are fresh and washed thoroughly, and internal organs such as gills and intestines are removed before cooking.
