Where do parasites hide in crayfish, and how do you kill them thoroughly?

On summer nights, what everyone loves most is still crayfish. Just thinking about drinking refreshing draft beer with spicy crayfish, the taste is so pleasant! But the problem is that crayfish generally grow in environments with poor water quality, so it is unavoidable that they contain many parasites. So where are the parasites in the crayfish body? How do you thoroughly kill them? Here is an introduction for everyone:

1. Where are the parasites in the crayfish body?

The crayfish body contains a large amount of bacteria and parasites, so it must be cooked thoroughly when eaten. So which part of the crayfish contains the most parasites?

1. The head of the crayfish is the place that absorbs and processes the most toxins, and it is also the part most likely to accumulate pathogenic bacteria and parasites. The head part of the crayfish must never be eaten. It especially must not be eaten raw, as serious cases can lead to paragonimiasis.

2. The intestinal tract and other digestive systems of the crayfish tend to accumulate heavy metals, so the digestive tract should be pulled out before cooking.

3. If you are not clear about whether the crayfish is clean or not, eat less of the crayfish roe, and it is best not to eat it at all. The crayfish roe is the gonad of the crayfish, and it is next to the liver, so it is also easily contaminated.

2. How do you thoroughly kill parasites in crayfish?

The crayfish body contains a parasite——the lung fluke, which mainly parasitizes the lungs in humans, and can also parasitize the brain, muscles, and other parts. Many people like to eat drunken shrimp and drunken crab, which in fact means eating shrimp and crab raw. This way of eating makes it very easy to ingest lung fluke metacercariae.

Parasitic infection can indeed cause disease. When lung flukes settle in the human lungs, patients can develop symptoms such as chest pain and coughing up blood; in lungs infected with lung flukes, nodules formed by the flukes can be seen; when they move to the brain, they can cause severe headache, epilepsy, decreased vision, and can even cause hemiplegia, aphasia, and so on. The methods to thoroughly kill parasites are as follows:

1. Wash carefully

Whether restaurants clean them properly is the biggest problem. But this is not a reason for you to reject crayfish! Because most restaurants today pay great attention to hygiene, and with strict supervision by the relevant departments, they do not dare to act recklessly either.

2. Cook thoroughly at high temperature

The vast majority of parasites and parasite eggs can be killed after sufficient high-temperature heating. Because the main parasite in the crayfish body is the lung fluke, but in fact many freshwater crustaceans can host lung flukes, so as long as the eating method is correct, cooking at more than 100 degrees Celsius for several minutes is enough before eating.

3. Do not eat the crayfish head

Lung flukes usually parasitize the digestive system of aquatic products, such as the head and gills of crayfish. It is recommended to simply pull them off to effectively avoid them.

Finally, the editor reminds everyone once again: the most effective way to prevent parasites from entering your mouth is to cook them thoroughly before eating!
