So the chicken has been been sitting in a ziploc bag with the marinade in the fridge since Monday night. Are they still safe to cook Wednesday, and how long can the un-cooked chicken be safely kept in the fridge? Uncooked chicken can be safely kept in the fridge for 2-3 days. But, marinate no longer than overnight. I like to make pasta sauce (with meat) a day before event. I use a slow cooker. I bring everything to a boil in it and then reduce it to 150 degrees F where it continues on and off and is always hot. I have left this at this temp for up to 48 hours steady. Is this safe. Guests just eat as needed, it even stays on thru the evening. Is this too long to simmer. This is not a safe practice. Once cooked, the sauce should not be kept hot for longer than two hours. And the cooking temperature is also not safe. To prevent the development of harmful bacteria, it should not be lower that 185 degrees F/85 degrees C. It would be safer to cook the sauce at a safer temperature and when cooked, remove from the pot and chill quickly. When ready to serve, reheat on your stove and transfer it to the slow cooker to keep hot while serving. What can I add to ground beef patties(hamburgers)so that after refrigeration and reheating the hamburgers will taste good and not have that funny leftover meat taste. Also
