    I remember reading on ATOT that it's better once it turns brown. Why does this happen though? This site says that beef is naturally dark and turns bright red when exposed to oxygen.. But I've left beef in the fridge for a few days, and it's turned from red TO brown. What's the deal??

    aging? *shrug* I dunno. I try to cook it as soon as possible, otherwise it goes in the freezer.

    it's natural, unless it's slimy or has a smell to it, it's fine. just keep it frozen and don't put it in the firdge for more than a day

    Aren't you only supposed to store raw beef in the fridge if you're defrosting it?

    Its the oxygen or something in the air. I work at a restaurant and the top pieces of meat like beef tenderloin, lamb and any other kind of meat in the stack will start turning brown while the pieces of meat under it will stay their natural dark red color.

    Well yesterday I bought some ground beef with a sell by date of Nov 22nd, and it's still in the fridge because I made burgers today, and will make some more tomorrow. It has a few brown spots inside.

    unless you cooked it, it's not alright to store raw beef in the fridge. freeze the raw stuff, fridge the cooked patties.

    they have a lower fridge setting than most fridges at home. their's run basically below freezing just like freezers, but there's an air-room temperature buffer so it acts like a supercool fridge

    Blood contain iron in it therefor it have colours. The colour of iron oxide (FeO, Fe2O3, Fe3O4 or a combination of any 2~3 forms) can range from red, mauve, maroon, brown, black, grey, green, pink, to yellow.

    I'm not saying it is. I just posted that because it's interesting. My fridge may be 30-35 though, because sometimes the top layer of my iced tea and milk freezes.

    geez...you'll be fine.

    If it says sell by you can put it in the fridge until then and a few days after and you will be fine. This is assuming the sell by date is only a day or two after the purchase date. If you know you wont' use it for a while - freeze it. Otherwise a little browning is normal and will not harm you.
