So I have this raw chicken breast that I haven't opened (sealed shut in the original plastic container) in my refrigerator for 5 days now and there is still 2 days until the expiry date printed on the label. Also note that, when I bought it from the supermarket they were keeping it in a normal refrigerator, not a freezer.
So my question is, if we're not supposed to keep chicken in the refrigerator for more than 2 days, how can supermarkets keep it in a refrigerator and sell it until the expiry date?
