Under normal circumstances, some adults parasitic in the human body can be expelled by taking medicine, but once the larvae of parasites enter the brain, liver, lungs or heart of the human body, it is difficult to treat them.
Second, freshwater fish and shrimp and clonorchiasis
Some folk sayings are not scientific, such as "eat crabs raw and shrimp alive". This is mainly because there are metacercariae parasites of Clonorchis sinensis in freshwater fish and shrimp, which can make people get Clonorchis sinensis, also known as liver fluke disease, and its symptoms are similar to hepatitis, so freshwater fish and shrimp must be cooked and eaten raw, such as sashimi, which is unscientific.
Third, raw snail meat is unscientific.
Some snails have parasites in their bodies. Because of the different growth stages of parasites, the harm to human body is also different. Agate snails should not be eaten raw, which can cause headache, nausea, vomiting, fever, intermittent drowsiness or lethargy; Some patients will also have various types of sensory abnormalities in the head, trunk and limbs, such as burning sensation, numbness and pain. Some patients will have visual impairment and blindness.
