Example Input: 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!
Example Output: Is it safe to eat a pork loin that has been refrigerated for 6 days?

Example Input: In Masterchef The Professionals (season 8 episode 11), Marcus Wareing demonstrates his skills test and cooks a burger.
