Abstract:
We observed the survival situation after treatments of Fasciola hepatica metacercariae by heating,drying and food seasoning.Results showed that after treating with microwave high fire and boiling water,all the metacercariae died.There were four metacercariae died after putting on the slide and dried them for 24 hours,while two died after attaching on the blade for 40 hours.The metacercariae all survived in the garlic,soy sauce,and vinegar liquid for 10,20 and 30 min;After 10,20 and 30 min soaking in the same amount of mixed liquor of the three kinds of condiments,saturated brine and the liquor of 38°,part of the metacercariae were survival.The rest of the metacercariae showed clear structures,but the bodies did not move with no obvious characteristic of death of metacercariae.Storing for 4 ℃ in the next 10 months,there was still the survival of metacercariae.In conclusion,the commonly used seasoning had no effect on metacercariae.Natural drying for 1-2 days could not completely kill the metacercariae.A low temperature for a long time could maintain vitality.Heating via boiling water for 10 sec or microwave high fire for 30 s could kill metacercariae.
