I was just pulling some mackerel out of the freezer to take to a BBQ later & found a bag of good frozen bone in proper fishmongers Tuna steaks - but they have a sell by date on the outer bag - can't say I've noticed that before, but tuna doesn't last that long around here for me to have noticed before, but these had fallen from sight/reach & were forgotten about?.. We tend to go by look, smell rather than SBD as I know they play very safe, so not sure what to do with these - seems a shame to waste them & they would be great on a BBQ :)
They are 6months+ out of date, look fine, no freezer trouble so I am sure they have been frozen solid the whole time?
Safe to eat or not ???
TIA
