Some people have done experiments, dissected 10 frogs, and found 28 sparganium mansoni in two of them, which is the main parasite of frogs.

Schizoster likes to curl up in the muscle space of frog, like a small white spot. It is only 0.5-2 cm long when curled up in the frog, and will stretch to 10-30 cm when put in physiological saline.

Sparganus has a strong vitality, which can't be killed by general frying. Only boiling water for 5 minutes can completely kill it. After people eat by mistake, the most common clinical manifestation is eyelid swelling, and sometimes it will invade the eyeball, leading to cataracts. The most serious disease is cerebral sparganosis, which can cause epilepsy and even paralysis.

Be careful, be sure to cook and eat!
