Are black prawns safe to eat
I bought some prawns yesterday at a supermarket. Although displayed on the fish counter with fresh fish, they were clearly frozen or partially frozen. I put them in the fridge over night.
Today, I've noted they've turned black. After a little research, it shows this could be due to oxidation, although others have commented they've never seen this before even if they've worked in "the" industry.
And one comment suggested that any black on prawns means they're spoiled and should be binned/destoryed. This is the part I'm sure of.
I have tried to wash with running water and can't remove this black colour.
There is no unexpected odour.
Sadly, I've also noted that the squid which I bought has released its link. Although all this fish was in the same outer bag, the squid was it its own bag and it doesn't appear to have leaked.
After taking the shell off, there isn't really any colouration to the flesh.
Is is possible to know if they are safe. Is this a known thing - that prawns turn black and it means either oxidation or that they're spoiled?

They look like they have been blanched. Or dipped in boiling water. The red.This is some times done if they have parisites on them. But froze? & shipped? I am talking about prawn fresh of the boat at home. Then blanched & froze at home for later use. I would avoid these if store bought. If I did not know they were boat fresh. How handled. Many prawn & shrimp are black in color. But not like that.

Is it OK to eat black prawns?
Once the shell is off, check to see if there is a black line running down the back of the prawn. This is the intestinal tract \u2013 if it's black, it's full. It's not harmful to eat, but the prawn looks better without it, and it can be a bit gritty. Removing it is called 'deveining'.Are prawns meant to be black?

Shrimp will occasionally have a shell discoloration called black spot or melanosis. This is not caused by bacteria and is not spoilage, but rather an enzymatic reaction caused by naturally occurring amino acids and sunlight. The shrimp are still be of good quality and safe to eat.How can you tell if prawns are safe to eat?
If your prawns are slimy or going grey, this may be a sign that they're too old. Slime on proteins is an indicator that lactic acid from bacteria is present, and this makes your prawns unsafe to eat. In general, seafood that smells overly fishy or funky should be tossed into the bin, as it may already be spoiled.What You Need To Know Before You Eat Another Bite Of Shrimp
