I was going to be funny... and say - "sure, if you don't mind diarehea" but, then I was afraid no one would find my toilet humor funny... so instead I will say - How cold is your fridge? As long as you keep it cold and you fully cook it = I would use use it. I tend to be a little lax with that, though... so you may not want to listen to me (esp. if you are preggers... or feeding small children... - then I would say do not use). You bought it Sunday - it's only Tuesday... In my fridge, it would be considered at it's peek of freshness... Oh dear, that doesn't make me sound good... Maybe I should go home and clean my fridge.
