Steps/methods:
1 First: Oncomelania usually grows near ponds or reservoirs. If the water quality is poor, they will be easily polluted, especially when the feces in snails are not cleaned up. Many parasites, such as Oncomelania hupensis, are the hosts of schistosomiasis.
2 Second: It is not recommended to eat fried snails during pregnancy. Even fried snails, because of the small heating surface and insufficient temperature, are not enough to kill parasites in snails, which is not conducive to the health of pregnant women. Therefore, it is recommended not to eat fried snails as much as possible.
Third, the cooked snails should taste fine, but it's hard to say if they are raw. There's no way to check.
Matters needing attention
Try not to eat. Snails themselves have a lot of bacteria, which is not conducive to digestion.
