I just did a quick Google check and I think you were looking at the pre-cooked time when it said 2-4 days. The USDA says cooked pork loin is good for 7 days in the fridge. And pork products are heartier than chicken and beef, because of the salt/brine process that they go through in the slaughter house to cure it, that helps it resist bacteria growth longer than poultry or beef products. My hubby grew up on a farm and his grandaddy pretty much had everything on his farm you could think of and they would keep the pork products out on the table for days and nobody got sick. I think you are going to be just fine and your anxiety over it is what is making you feel potentially yucky. HTH!
