The Bureau of Fisheries and Aquatic Resources (BFAR) on Wednesday advised the public that shellfish caught from several areas in Bataan, Palawan, and other provinces have been found to have paralytic shellfish poison beyond the regulatory limit.

The public is warned against the consumption of shellfish from the following areas:

  • Coastal waters of Bataan (Mariveles, Limay, Orion, Pilar, Balanga, Hermosa, Orani, Abucay and Samal);

“All types of shellfish and Acetes sp. or alamang gathered from the areas shown above are NOT SAFE for human consumption,” it said.

“Fish, squids, shrimps, and crabs are for human consumption provided that they are fresh and washed thoroughly, and internal organs such as gills and intestines are removed before cooking,” BFAR added.

According to the Washington State Department of Health, Paralytic Shellfish Poison (PSP) is a naturally occurring marine biotoxin produced by some microscopic algae species.

“Shellfish eat these algae and can retain the toxin. People can become ill from eating shellfish contaminated with Paralytic Shellfish Poison. This biotoxin affects the nervous system and paralyzes muscles, thus the term “paralytic” shellfish poison. High levels of Paralytic Shellfish Poison can cause severe illness and death,” it said.

Bivalve molluscan shellfish such as clams, mussels, oysters, geoduck, and scallops can accumulate Paralytic Shellfish Poison. So can moon snails and other gastropods. Other marine species, such as sea cucumbers, might be affected. Crab, because they feed on shellfish, can also become toxic.
