“Fish, squids, shrimps (except their heads) and crabs are safe to eat so long as they are fresh and washed thoroughly, and internal organs such as gills and intestines are removed before cooking,” the DOH said, noting that the advisory was based on Department of Agriculture – Bureau of Fisheries and Aquatic Resources Shellfish Bulletin No. 05, series of 2024, issued on Friday.

The DOH also warned that signs and symptoms of paralytic shellfish poisoning have a rapid onset and can be felt within 12 hours after consuming the unsafe shellfish.

Among its symptoms are “numbness around the mouth or face; dizziness; pricking sensation and/or paralysis of hands and feet; body weakness; rapid pulse; difficulty talking, swallowing, or breathing; and headache.”

There may also be abdominal pain, diarrhea, and vomiting, the DOH added.

Health Secretary Teodoro Herbosa advised patients with symptoms to go to the nearest emergency room.


“Prevention is the best: do NOT eat tahong, talaba, halaan, other shellfish, and alamang from areas identified with toxic red tide. Always read advisories from DA-BFAR and the DOH. All hospitals are directed to prepare for these cases and to report them accordingly,” he said as quoted in the statement.
