ABSTRACT
gastrointestinal and cardiac symptoms, and in some cases, chronic neurologic symptoms. In the Philippines, diagnosis
experienced temperature reversal sensation. Cigua-Check Kit screening done by the Bureau of Fisheries and mass spectrometry, which showed masses corresponding to those of CTX-1 and CTX-3B/3C. Since an increased occurrence of CFP in the Philippines is anticipated as a consequence of global climate change, validation of CFP by other methods like mass spectrometry will be useful for more effective diagnosis and management of CFP.

Figure 2. Electrospray mass spectra of extract from blood sample collected from patient who was poisoned upon the ingestion of red snapper (Latjanus campechanus, locally known as mayamolecule (m/z = 18) is a characteristic fragmentation pattern for CTX-1 (Caillud et al. 2010, Chinain et al. 2010).
