Yes, you should refrigerate hamburger meat or it will grow bacteria more quickly than if it was left out at room temperature..
In general a good rule of thumb is to throw out any food that has been in your fridge for more than a week.
You did exactly what you were supposed to do. The turkey should be just fine.
i think it is because when you leave an apple that has been cut open it reacts with the air. the apple in your smoothie has reacted with the air and gone brown. it should be ok to drink but it depends on how long it has been in your fridge for.
The fizz should stay longer if kept in the fridge because if you take away energy (make it cooler) you will lower the solubility meaning that it won't saturate the air in the fridge.
If they've been accidentally (or purposefully) left out overnight, they should not be eaten.
Fridge in slang means someone who is cold like a fridge and therefore, hasn't been kissed.
First of all, meat should not be allowed to thaw out overnight outside of the fridge - especially hamburger. Even with that mishandling, if the ground beef still smells and feels like fresh hamburger with no off odors or sliminess and you decide to use it, make sure it is thoroughly cooked. It is your decision whether or not to use it, but no one here can tell you it is safe to use. When in doubt, don't.
The general rule is that once jam, or any perishable food, has been opened it should be returned to the fridge within 2 hours.
Uncooked meat is not safe to eat, in general. As for cooking it, a brown color can indicate that the hamburger is not freshly ground, that it has oxidized or possibly spoiled. Unless it has been under proper refrigeration since ground (where it may have been photo-oxidized by UV light), it should be suspected as spoiled.
No, definitely and absolutely not! It's a recipe for food poisoning.If frozen meat has thawed you can freeze it again AFTERit has been properly cooked. When the cooked meat is thawed, it must not be frozen again. It is just too risky.

Depending how the raw hamburger has been packaged and handled, it might not be safe to use. Only you, the consumer, can determine whether you should use it. If the hamburger has been handled and stored properly and looks, smells and feels acceptable, then it is probably OK to cook. Unless it has been stored in a super chill drawer, it is probably starting to turn. It may even have a vinegary fragrance or tang to it due to bacterial growth. You'll have to decide whether it is worthwhile using.
