Bought on Monday (29th April) from Asda, straight home and into fridge, use by 6th May.
Opened tonight, still vacuum packed tight (not blown) perfectly normal appearance - but had a faint smell. A bit more than just a bit "chickeny", enough that I could smell it on the tongs I used to put them in the pan, but it disappeared after about a minute of starting to cook and then they smelt normal.
That's alright innit?
