I'm a non-fish eater (it's against my religion ) but bought some salmon fillets for my baby and totally forgot about them. Their use-by date is the 29th. Do I need to chuck them or is there a way to tell if they're okay to use (for my 7m old baby)?
If it was for yourself I would say have a sniff and if it doesn't smell too fishy then it is probably okay. However, I would not take a chance with a 7 month old baby - can you imagine how you would feel if you gave your small baby food poisoning? I don't think it is worth it.
Sorry... I'm always occasionally not remembering the dates on stuff and have always gone by the 'if it looks, smells and feels ok, then it is ok'. All four DC have been fine over the pst 18 years. Youngest is 2 and eats day/two day out of date fish etc. The only thing I wouldn't do would be clams, prawns, mussels etc.
If worried, I'd just quickly fry a little bit, get DH to taste - he will know if it's absolutely fine immediately. Seriously, though, if it smells (to him) every so slightly not fresh, don't use it. If it doesn't then imo it will be fine.
