Does it smell ok? Years ago I used to hunt with a city food/restaurant inspector. I pulled out a supposed fresh steak that had a funky smell. I was ready to toss it. He smelled it and gave me his and said he would eat it. He first washed it throughly. Mine was a much better cut of meat than his LOL.
He told me that Steaks and other dense cuts of meat may begin to get a bacteria smell on the surface, but due to the dense meat it was most likely, only superficial. Now, that being said, I am not afraid of a dense steak maybe having a slight odor then being well cleaned before use. Pork? Well, I guess it depends on the cut and how much fat? If it smells okay, and you cook it to a minimum of 165* IT I would most likely not hesitate. JUST MY two Cents worth. Your mileage may vary.
