When it comes to leftover turkey, I recommend eating it within 3 to 4 days. After that point, the turkey may be at risk for things like bacteria. Always be sure to give the leftover turkey a little sniff test and a look-over if you're looking to eat the leftovers after 5 days or longer. And if you really need your turkey to last, it can be kept in the freezer for up to 4 months.
