Detoxification of Pyrodinium-generated paralytic shellfish poisoning toxin in Perna viridis from Western Samar, Philippines RQ Gacutan, MY Tabbu, MTR de Castro, AB Gallego, ML Bulalacao, L Arafiles & F Icatlo Jr. - In AW White, M Anraku & KK Hooi (Eds.), Toxic Red Tides and Shellfish Toxicity in Southeast Asia. Proceedings of a Consultative Meeting, 11-14 September 1984, Singapore, 1984 - Marine Fisheries Research Department, Southeast Asian Fisheries Development Center; International Development Research CentreThe results are presented of procedures for the detoxification of paralytic shellfish poisoning toxin using ozone, chlorine and PVP-iodine. Findings indicate ozone and PVP-iodine to effectively inactivate the toxins isolated from Perna viridis ; however, further investigations are recommended.
Paralytic shellfish poisoning due to Pyrodinium bahamense var. compressa in Mati, Davao Oriental, Philippines On 26 August 1983, a single case of paralytic shellfish-poisoning (PSP) was reported in Davao City, Philippines. The poisoning was traced to ingestion of the green mussel Perna viridis Linnaeus, gathered from Balete Bay, Mati, Davao Oriental. Phytoplankton and zooplankton analyses on 12 October 1983 (47 d later), revealed the presence of the dinoflagellate Pyrodinium bahamense var. compressa, a cause of a series of red tides in the early and middle 1970's in Papua New Guinea, Sabah, and Brunei, and more recently, in Palau, and Western Samar and Leyte, Philippines. The dinoflagellate was not dominant; in fact the enumeration showed greater numbers of Ceratium sp., another dinoflagellate. Quantification of the neurotoxin by the standard mouse assay revealed a very high potency. Mussels collected from a new raft (transplanted in May 1983) had a toxicity of 7 960 mouse units (MU) per 100 g-1 meat. Those from an old raft (transplanted in May 1982) had a toxicity of 9 620 MU per 100 g-1 meat.
