Are there parasites in prawns?

Many friends are actually worried about whether there are parasites in prawns. For some friends who like to eat shrimps, just cook the shrimps until they are fully cooked and do not eat the shrimps' heads. This can effectively prevent and control the parasites in the shrimps. Whether prawns contain parasites is generally related to the environment in which they grow.

The experimenters separated the crayfish head and body, sucked out the tissue fluid from the crayfish head with a pipette, placed it on a prepared glass slide, and observed it under a 1600x microscope. At this moment, a picture that made everyone present extremely uncomfortable appeared on the computer screen connected to the microscope: swimming worms could be clearly seen under the lens, and there were more than one, some in linear shape, and some in oval shape.

"It is certain that there are parasite eggs in this crayfish." Common parasites in crayfish are lung flukes. If you eat crayfish infected with lung flukes, you can easily be infected with lung fluke disease. Lung flukes can survive in the human body for more than a year, or even several years, and are the cause of many diseases in the body.

When cooking crawfish, always heat over high heat. When cooking crayfish, the temperature must reach above 100 degrees Celsius and last for at least 5 minutes. In addition, cleaning before eating is very important. Be sure to use a brush to clean the dirt on the crayfish's body. At the same time, the intestinal thread that hides a lot of mud and bacteria must also be removed.

The head of the crayfish is not edible. ", the head of the crayfish is the part that absorbs and processes the most dirt, and is also the part that is most likely to accumulate pathogens and parasites. In addition, when eating crayfish, try to use live shrimp for cooking and consumption, because crayfish will rot quickly after death, and will decompose to produce toxic substances such as histamine, which will breed harmful bacteria.

① Parasites generally have an infection rate, which means that not all animals will be infected, and it is difficult to guarantee that one will have worms if you pick one up at random.

②The video shows that the "bug" seems to be very soft and it actually broke when being picked out with a toothpick, which is not normal.

③If it is really a bug, and it is so common, why is this not included in the shrimp inspection procedures?

④ In a breeding environment, if there are so many parasites, the health of the shrimp must be very poor.

If farmers do not want to lose all their money, they will definitely use drugs to control the disease. Therefore, from an economic perspective, such serious parasitic infections will not occur.
