Summer favorite food TOP list, crayfish must be many people's No.1, garlic, spicy, thirteen spiced, secret, curry, think can make people drool. "Summer without eating crayfish once is not called summer." Eating crayfish has almost become the norm in summer.
However, doubts about crayfish have also been heard. Shrimp yellow is shrimp, can't be wordy? Shrimp head heavy metal exceeding the standard? Can it really be eaten? "Do you want to go to the shrimp line?" "Can't crayfish be eaten with beer?" "Aren't there a lot of parasites?" Jiangsu Cdtec answered questions about crayfish.
Can shrimp heads be eaten? Can eat, but it is recommended to eat less!

Is the yellow shrimp in the shrimp head part?
Of course not! Shrimp yellow generally refers to the liver of crayfish, when the mother shrimp reaches maturity, its ovaries will also be called shrimp yellow (have you ever eaten the orange-red and slightly hard shrimp yellow). Shrimp yellow taste delicious, and rich in nutrients, rich in unsaturated fatty acids DHA, EPA, protein, trace element selenium, and various vitamins.
Shrimp head with heavy metal residues and parasites?
Crayfish are very sensitive to heavy metals, in the heavy metal exceeding the standard of water, crayfish can not successfully dehull, can not survive, poor water quality yield will be three or four times worse, so in the heavy metal exceeding the standard of water is not suitable for breeding crayfish. Current research data show that the heavy metal content of crayfish has obvious parts differences, except for the shell, most of the heavy metals in the crayfish are concentrated in the gills and internal organs, while the gills and internal organs are mainly concentrated in the head.
There is a real risk of parasites in crayfish, and the lung flukes carried by crayfish usually parasitize parts such as the head and gills of crayfish. To sum up, shrimp heads are the places where the most toxins are absorbed and treated, and where pathogenic bacteria and parasites are most likely to accumulate. Therefore, it is recommended that you do not eat or eat less crayfish head.
Have you eaten a lot of shrimp heads?
Don't panic, lobster is a seasonal food, and the amount of consumption may be large in the short term, but it is still less on average throughout the year. Considering that the lobster currently eaten on the market is mainly farmed, the concentration of heavy metals is relatively light. As long as you don't eat every day, eat every meal, and eat all year round, then the part that has already been in the stomach does not need to panic, and you can pay attention to it later.
Parasites are terrible things, but it is also very simple to eliminate them, that is, to cook the shrimp completely through high-temperature cooking, and the probability of parasites appearing is very small. Half-baked crayfish don't venture to try.
Shrimp noodles are dirty and can't be eaten?
Shrimp line is the "digestive tract" of crayfish, that is, the place where lobsters are excreted, often easy to accumulate heavy metals, and the shrimp line should be pulled out before cooking.
If you accidentally eat the shrimp line, it is not much trouble. After the shrimp is cooked at high temperature, the bacteria in the shrimp line will be killed by the high temperature, and eating it will not have much impact on the body, but it may have a muddy smell and the taste will be worse.
Who eats crayfish carefully?
Although the crayfish is delicious, don't be greedy and avoid eating crayfish frequently and in large quantities in a short period of time. These people eat crayfish with caution:
People with allergies, crayfish are high-protein foods, and people with allergies may have allergies when they eat them.
In patients with hyperuricemia or gout, crayfish purines are high.
Pregnant women, the elderly, children, the infirm, if the crayfish are not washed or cooked, it is easy to cause acute gastroenteritis and parasitic infections.
