        The present study investigated the intra-vitam larval migration of Anisakis pegreffii, which is naturally infected, from the intestine to the viscera and the musculature of live spotty-bellied greenling, Hexagrammos otakii, under the different seawater temperatures. The results showed that the increase in the ratio of larval migration from the intestine to the viscera correlated with the increase in the water temperature in the aquarium. The intra-vitam larval migration ratios from the intestine to the viscera were 60% (63/105) at 15°C, 1.64% (3/183) at 12°C, 1.16% (2/172) at 9°C and 1.42% (2/141) in the control group (7.5°C). The free larvae showed no, slight and strong movement at 9°C, 12°C and 15°C, respectively, in saline water, and the larvae were present in a coiled state at 9°C and 12°C. The results suggest that temperature plays an important role in the intra-vitam larval migration of A. pegreffii. In addition, the free larval behavior of A. pegreffii in vitro increased with increase in temperature. Therefore, to prevent human anisakiasis caused by the consumption of raw fish, it is important that the temperature of the aquarium must be maintained below 12°C, which is the critical temperature zone.

        We studied the infection rate of and various metacercariocidal approaches to controlling Gymnophalloides seoi for prevention of human infection in cultured and natural oysters in Korea. The selected survey areas were Aphae-do (Shinan-gun, Jeollanam-do), which is an endemic area for G. seoi, and Tongyeong (Geonsangnam-do), which is the main production area of oysters in Korea. In the Tongyeong area, the metacercariae of G. seoi were not detected in cultured oysters (0/201) or wild oysters (0/134). Seventy-two G. seoi metacercariae were observed in 33 of 265 natural oysters collected from Aphae-do; however, metacercariae were not detected in the cultured oysters (0/1101) purchased from the Daejeon Fish Market. To investigate the viability of G. seoi metacercariae, various metacercariocidal treatments were used with 3.5% saline and oyster juice used as positive controls. The metacercariae survived for 75.4 h in 3.5% saline and 112.6 h in oyster juice. After the metacercariocidal treatment, G. seoi metacercariae were survived for 13.29 min in tap water, < 20 sec in 4.3% vinegar, no effect in a rinse of the whole oyster body in 70°C water for 1 sec, but 1 sec in a rinse of the whole oyster body in 90°C water for 1 sec. The greatest metacercariocidal effect on G. seoi was from rinsing oysters in 90°C water followed by those from treatment with 20% ethyl alcohol, 4.3% vinegar, and tap water. However, we suggest that the most actual prevention to G. seoi human infection is rinsing the oysters with tap water for at least 30 min.
