Any Fish (Tuna) Experts on here ?

[Buckster]

Bought some Tuna Steaks today - same as we have every week (once a week) - fresh - not frozen

when unpacked noticed they had a very very distinct pink (with a bit of irridescence) sheen to the surface (of both) - and same on rear side.

not seen anything like it - insome light angles was not so noticeable but others was very very noticeable indeed.

did some research on the internet and it implied that this could be a "rainbow sheen" which could show the fish is "off" or not preserved properly - Scromboid bacteria orsomething.

we decided to not risk it- but for future - anyone know whehter this is safe to eat or not please ?

this must be our 15th or so pack of fresh Tuna and I've not seen this effect at all before.

actually we used to eat frozen tuna steaks and its one of the few fish that for me - it doesn't work out so well - texture etc didn't seem as nice

we eat a lot of haddock, salmon, cod etc (wife is a pseudo vegetarian - I'm not so we have fish nearlly every meal - and I have meat at lunch in my sandwiches)

cheers

I think so - they were from one of the major supermarkets from memory - but they put me off because they had lots and lots of thick blood veins in them after cooking - didn't affect taste but was rather nasty

these "fresh" ones have been from Ocado and are really really nice indeed
