Is it safe to eat a pork loin that has been refrigerated for 6 days?

Question

I've accidentally left a pork tenderloin marinating in the fridge for the past six days. Is it still safe to cook and eat? I'm not sure how it will taste, but I'd hate to waste a good tenderloin. The marinade is really more of a brine made of apple juice, sugar, soy sauce, salt and some spices. It was in the back of refrigerator, so it remained quite well chilled.

Update!

As many folks mentioned, I used the power of The Sniff Test and everything smelled fine. We ate it and no one died or fell ill. In fact, it was quite tasty. I was afraid the taste would be off, but it was great!

Answer

I once left a whole New York strip in the walk in cooler for two weeks and it was great. Chances are that the salt and acid in the marinade preserved the pork well enough it would still be safe to eat after six days. I would check for slime and foul odor. There are several other factors involved such as how it was handled before put in the refrigerator. For example, a piece of pork that was at room temp for one hour with a semi sterile knife trimming it might not last three days. I always go with whether it has an off odor or not. I find that meat which has aged a little in the fridge will have a more robust defined flavor. If you run your finger across it and feel any type of slime just get rid of it.
