I bought a fresh turkey this year. The tag says it is good until sometime in December. It has been in my refrigerator since November 20th.

Hi Kim! According to the USDA, fresh turkey should only be stored in the fridge for two days. I'd suggest giving the turkey a texture and smell test, if the skin looks slimy or it smells like rotten eggs, it's spoiled. That being said, you can't smell or see foodborne pathogens, so in any case, I think you may want to be safe than sorry and consider picking up a new turkey.
