The shrimps, a bowl, a two-tined cooking fork.

What you’ll need to do: 

  1. Cut the head of the shrimp.
  2. Look for the vein. It may be hidden in plain sight so look for a dark dot just under the shell.
  3. Place one of the tines of your two-tined fork on the black dot or vein that you can see.

Is there vein on shrimp poop?

The vein in shrimp is actually not a vein, rather it is its intestinal tract. This means that the shrimp’s digestive processes happen in this tract. 

The tract contains shrimp feces or partly digested food. Although it contains mostly bacteria, eating it is not harmful. This is the reason people devein the shrimp because even though it is not harmful, the thought is unappealing. 

Do restaurants devein shrimp?

Most restaurants do. While some other restaurants buy already deveined shrimp to cut the stress and time. It may not be unusual to come across a shrimp that hasn’t been deveined in a restaurant, especially the small-sized shrimps.
