The meat of crayfish is tender and spicy, and it tastes spicy and delicious. It is one of the Internet celebrity delicacies in summer. Many people eat crayfish regularly, especially young people.

Crayfish grow in water, so there are some parasites. Even if you only eat the tail, if you eat it undercooked, you still have the risk of being infected with parasites.

1. Will crayfish have parasites if they only eat their tails? There will also be parasites.

Including aquatic and edible species such as crayfish and crabs, they all have parasites in their bodies to a greater or lesser extent.

Therefore, if eaten raw or undercooked, it is easy for us to be infected with parasitic diseases, etc.

According to relevant research and testing reports, there are many moving oval parasitic eggs in crayfish after ultrasonic cleaning, but when we eat them at a temperature of 50°C and heat them for 10 minutes or more, the parasite eggs will

disappear.

Therefore, be sure to eat cooked crayfish, otherwise there is a threat of parasitic disease.

2. Will there be any problem if you only eat the tail of crayfish? Generally, there will be no problem if you eat it cooked.

Improper handling of crayfish will make it unhealthy to eat, mainly because of the presence of Paragonimus, which can easily cause "rhabdomyolysis".

Generally speaking, crayfish and crabs carry Paragonimus, and roasting, frying, or pickling them is not guaranteed to kill the larvae.

Therefore, crayfish must be cooked thoroughly.

When cooking, soak the crayfish in water for two to three hours, then brush them clean and cook them at high temperature.

Generally speaking, if you boil crayfish for more than 40 minutes, the parasites can basically be killed and then cooked.

3. What parts of crayfish should not be eaten? It is best not to eat the head, gills, intestines and yellow color of crayfish. Experts remind that it is best to remove the head, gills, intestines and yellow color of shrimp that many people like most. It is best not to eat them.

Generally speaking, heavy metals tend to accumulate in the digestive system such as the intestines of crayfish, so the shrimp threads should be pulled out before cooking.

Although the head and gills are where heavy metals accumulate, they are generally not edible.

If you don't know whether the shrimp is clean, you should eat less shrimp yellow, and it is best not to eat it.

Because from the perspective of testing, shrimp meat is very safe and generally does not have heavy metal contamination. However, in some samples, the heavy metals in shrimp brain may exceed the standard.

The shrimp roe is located on the head and is easily contaminated.

In addition, experts specifically remind that the head and gills of crayfish are the main parts of the body, so it is recommended not to eat them.

Experts say that crayfish itself is non-toxic, and normal consumption of crayfish generally does not cause illness.

The cause of the disease may be problems in crayfish farming, cleaning or cooking, or it may be due to factors such as pollution that carry certain substances.

If symptoms such as muscle soreness and stiffness, soy sauce-colored urine occur after eating crayfish for half a day to a day, it is indeed a cause for concern and you should go to a regular hospital immediately.
