  abstract = {{C}iguatera fish poisoning is a seafood intoxication commonly afflicting island communities in the {P}acific. {T}hese populations, which are strongly dependent on fish resources, have developed over centuries various strategies to decrease the risk of intoxication, including the use of folk tests to detect ciguateric fish. {T}his study aims to evaluate the effectiveness of two folk tests commonly used in {R}aivavae {I}sland ({A}ustrales, {F}rench {P}olynesia): the rigor mortis test ({RMT}) and the bleeding test ({BT}). {A} total of 107 fish were collected in {R}aivavae {L}agoon, among which 80 were tested by five testers using the {RMT} versus 107 tested by four testers using {BT}. {F}irst, the performance between testers was compared. {S}econd, the efficiency of these tests was compared with toxicity data obtained via the receptor binding assay ({RBA}) by assessing various parameter's values such as sensitivity ({S}e), specificity ({S}p), positive predictive value ({PPV}) and negative predictive value ({NPV}). {C}omparisons of outcomes between folk tests and {RBA} analyses were considered: tests used separately or in a parallel versus the series approach by each tester. {T}he overall efficiency of the {RMT} and {BT} tests was also evaluated when the judgments of all testers were pooled. {T}he results demonstrate that efficiencies varied between testers with one showing the best scores in detecting toxic fish: 55% with {RMT} and 69.2% with {BT}. {BT} gave the best results in detecting toxic fish as compared with {RMT}, giving also better agreement between testers. {I}f high {NPV} and {S}e values were to be privileged, the data also suggest that the best way to limit cases of intoxication would be to use {RMT} and {BT} tests in a parallel approach. {T}he use of traditional knowledge and a good knowledge of risky versus healthy fishing areas may help reduce the risk of intoxication among communities where ciguatera fish poisoning is highly prevalent.},
