The Bureau of Fisheries and Aquatic Resources (BFAR) has released a new alert bulletin on the continuing red tide contamination of Puerto Princesa Bay.
Shellfish Bulletin No. 21 from the fisheries bureau said the ban on the gathering of shellfish from the affected area is still enforced.
The public warning was issued after samples of shellfish collected still yielded positive results for paralytic shellfish poison (PSP) that is beyond the regulatory limit.
“All types of shellfish or alamang gathered from affected areas are not safe from human consumption,” the advisory said.
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 5 to 12 hours.
