Paralytic shellfish poisoning surveillance in California using the Jellett Rapid PSP test

From January 21 to December 23, 2004 a total of 910 JRPT were completed; the testing yielded 478 negative, 147 positive, 259 false positive, 20 indeterminate and 6 invalid results. Animal usage was decreased and analyst time was conserved when a negative screen was obtained. The study confirmed the JRPT could be used for PSP surveillance in California on a year-round basis without a negative impact on public health.
