Many people think that parasites and germs will be hidden in the shrimp line. Is that true? This article will tell you about these problems of shrimp line.
Shrimp line, generally black and cyan, is the residual excreta in shrimp intestine. So in theory, it's really a little dirty. It's better to remove it. But if you don't bother to remove or eat shrimp without shrimp line, don't worry, because they are also safe.
Most of the shrimp we eat in life will be cooked (cooked). The high temperature can kill the bacteria in the shrimp line, so there is no problem eating it, that is, it may taste worse and make people feel sick.
In addition, whether shrimp heads can be eaten has always been controversial. Previously, in a variety show, there was a heated debate between host he Jiong and actor Qi Wei.

So can you eat shrimp head? The nutritionists in the explosion nutrition class think that we should look at the situation:
It must be recognized that any organism can transport and accumulate low concentrations of chemicals in the environment to high concentrations through the food chain. And theoretically, the higher the animals, the more chemicals they accumulate.
For example, crayfish, the favorite of Chinese people, can enrich harmful substances such as heavy metals in the living environment, mostly concentrated in gills and viscera, that is, mainly in the head, so many people think they can't eat shrimp head.
However, the heavy metals in shrimp generally come from water and feed. If the shrimp are regularly cultured, the water quality and feed will not be poor, otherwise the shrimp will not survive. The living environment of shrimp is free of harmful substances such as heavy metals. How can the shrimp head not be clean?
Generally speaking, as long as the shrimp is formally cultured, the shrimp head can be eaten, and the safety can be guaranteed. In fact, many big hotels have special dishes made with shrimp head, and some places have the habit of eating shrimp head sauce.
But if you get shrimp from unreliable channels, such as crayfish caught by yourself in the smelly ditch, you'd better not eat shrimp head. Of course, if you are really worried, you don't have to worry too much. Just eat shrimp. Anyway, there isn't much meat on your head.
