MANILA The ban on consuming all types of shellfish including "alamang" (acetes sp.) collected in parts of Palawan, Bohol, and Western Samar provinces stays due to the presence of red tide toxins, according to the Bureau of Fisheries and Aquatic Resources (BFAR).
Based on the latest laboratory results, BFAR said "shellfishes collected at Puerto Princesa Bay, Puerto Princesa City in Palawan; coastal waters of Dauis and Tagbilaran City in Bohol; Irong-irong, San Pedro, and Silanga in Western Samar; and Cancabato Bay, Tacloban City in Leyte are still positive for paralytic shellfish poison that is beyond the regulatory limit."
All types of shellfish, including alamang, from these areas "are not safe for human consumption," it added.
Last August, BFAR raised an alert for red tide toxins in parts of Palawan, Western Samar, Surigao del Sur, and Bohol due to the presence of paralytic shellfish poison beyond the regulatory limit.
However, it clarified that fish, squids, shrimps, and crabs are safe to eat "provided that they are fresh and washed thoroughly, and internal organs such as gills and intestines are removed before cooking".
Red tide is a term used to describe a phenomenon where the water is discolored by high algal biomass or the concentration of algae.
Consuming shellfish with red tide toxins may affect an individual's nervous system within 30 minutes.
Initial reactions may include tingling, first in the lips and tongue, spreading to the face, neck, fingertips, and toes.
Other symptoms include headache, dizziness, and nausea.
In severe cases, people may experience muscular paralysis and respiratory difficulty within five to 12 hours. (PNA)
