How to Clean Shrimp. Shrimp that haven’t been deveined aren’t edible.
The thin black “vein” that runs through the shrimp could be harmful if eaten raw.
That’s the shrimp’s intestine, which has a lot of bacteria like any other intestine.
Cooking the shrimp, on the other hand, kills the germs. So you can eat cooked shrimp with “veins” and all.
The decision to devein shrimp is based on personal preference and aesthetics rather than hygiene, and the vein is not harmful to the human body if consumed. If the vein can be seen through the shell and meat, and you find the digestive tract unappealing and unattractive, it’s time to remove it.
