Abstract


In this study, author tried to confirm the Clonorchis sinensis infectiousness or gate of the metacercariae in fresh-water fishes which were treated with var-ious cooking methods being prevalent through our coun-try, so that two fresh-water fishes(Psudorasbora parva) harboring C. sinensis matacercariae in the flesh were given to each rabbit after treated by various cooking methods and, proper period later, liver, common bileduct and gall bladder of the rabbits were examined to direct C. sinensis worms.
And the following results were obtained.
1) In control group,m no treatment was given. almost of all C. sinensis metacercariae in flesh of Pseudorasbora parva were alive through 3days´ preservation in room temperature of about 10??, and by administering the fishes to rabbits about 500C. sinensis worms per fish, in average, were detected.
2)In group in which P. parva were soaked in soy??flavoured with vinegar, C. sinensis metacercariae in flesh of the fishes were not killed completely after 24hrs´ treatment.
3) In group in which P. parva were treated with boiling water, all C. sinensis metacercariae in flesh of the lishes were killed completely after 1 minute´s treatm-ent.
4) In group in which P. parva were freid in hot olive oil(300??), all
C. sinensis metacercariae were killed co-mpletely after 10 seconds, treatment.
5) In group in which P. parva were broiledx on fire (300~350??), flesh of the fishes were almost completely boiled after 30 seconds, treatment, but there was possibility of remaining of a few alive metacercariae in the flesh.
6) In group in which P.parva were salted, all C. sinensis metacercariae were killed comnmpletely after 48hrs´ tratment.
7) In group in which P.parva were dried under sunlight(about 10~15??), water content of flesh of the fishes was 12.4% after 3 days´ treatment and almost of all C. sinensis metacercariae were killed but not for a few.
8)By cooking procedures of P. parva the utensils used and washed water of the fishes were contaminated with C. sinensis matacercariae.
