| Abstract | Paralytic shellfish toxin (PST) is a potent marine neurotoxin produced by dinoflagellates, accumulated in shellfish, and responsible for paralytic shellfish poisoning (PSP). This study conducted food safety risk profiling of PST in mussels and oyster consumed by the Filipino population through [1] determination of data gaps in the risk profile of PST in the consumption of mussels (Perna viridis) and oysters (Magallana bilineata) by the Filipino population; [2] identification and characterization of PST as a hazard in mussels and oysters based on literature review, [3] estimation of dietary exposure (DE) and risks based on uncertainties, variabilities, and assumptions, and, [4] consolidation of available control measures and possible mitigation protocols of PST in mussels and oyster. Gaps such as the absence of no-observed-adverse-effect level (NOAEL) and limited information on dose-response studies for PST were identified in the Philippines. The estimated DEs of adults for the mean (mussels: Asian average=8.3650 µg/kg bw; male=7.2912 µg/kg bw; female=8.1000 µg/kg bw; oysters: Asian average=10.9551 µg/kg bw; male=9.5488 µg/kg bw; female=10.6079 µg/kg bw) and high (97.5th) consuming population (mussels: Asian average=28.1635 µg/kg bw; male=24.5482 µg/kg bw; female=27.2710 µg/kg bw; oysters: Asian average=43.4936 µg/kg bw; male=37.9104 µg/kg bw; female=42.1152 µg/kg bw) were calculated using consumption data from DOST-FNRI (2022) and levels of PST obtained from BFAR (2003). The results exceeded the provisional lowest-observed-adverse-effect level (LOAEL) and acute reference dose (ARfD) values, 2 µg STX eq/kg bw and 0.7 µg STX eq/kg bw respectively, set by the Joint FAO/IOC/WHO ad hoc Expert Consultation on Biotoxins in Bivalve Molluscs in 2004 indicating high risk of PST in mussels and oysters. Control measures for PST in mussels and oysters in the Philippines include PNS/BAFS 89:2021 and PNS/BAFS 207:2017. |
