i have a mist twst can case but the date on the bottom of it shows dec 19 2016
Even if it is an expiration date, Dec. 19, 2016 is only a little over a month ago. If the cans are sealed, the soda inside can't possibly have gotten significantly more toxic than it was on the good-until date, just by aging for 34 more days. Go ahead &amp; drink it. 

stilltasty.com is a good reference.
