Totally, twenty seven specimens of tiger puffer, Fugu rubripes rubripes were collected at Jagalchi fish market in Pusan, Korea during January, April and September in 1995. Anatomical distribution of pufferfish toxin in tiger puffer was examined by mouse bioassay. The frequency rate of toxic specimens containing ≥ 10 MU/g was 14.8% in liver; 16.7% in gonad; and 14.8% in skin, and no toxin was detected in muscle. The highest toxin level found was 160 MU/g in liver, 600 MU/g in gonad and 26 MU/g in skin, and each average toxin level (mean ± standard error) was 7 ± 6, 50 ± 35 and 5 ± 1 MU/g, respectively. Some specimens collected in January and April were toxic, while none of the specimens collected in September showed its toxicity. Although toxicity of tiger puffer showed the seasonal variation, tested tiger puffer was evaluated as a safe seafood for consumption, in that an acceptable level of toxin was found in the edible muscle and skin.
