Yes. Butter can be kept at room temperature (below 80F) up to a month, if it is protected from air. The most popular way to do this is with a "French butter keeper", a cup that is inverted into water. That particular design was invented a little over 100 years ago, but methods for keeping butter fresh without refrigeration have been around for centuries.
Yes, not all butter is salted. If you leave any butter out for several days at room temperature it will become rancid, the same as any other fat-containing food. You will know when it is unfit to eat because of unpleasant changes in the texture, color and smell. Butyric acid is one pungent component of the decomposition of butter and it is also found in vomit (see link).ANS2:No - Salt is a preservative.
Butter will be OK for at least a couple days after the power goes off. The concern is more about quality and rancidity, not food pathogens.
Not really if you are not on a salt restricted diet: the amount of salt in butter isn't too high unless you are eating a lot of it. The reason for unsalted butter is that some recipes that use a lot of butter might taste a little too salty if you use the salted kind (shortbread, for example). Also, if the butter is not salted you can better control how much salt goes in the final recipe. HOwever, unsalted butter does not last nearly as long because salt is a preservative, so you should use it quickly and freeze it if you are keeping it more than a few days.
A peanut butter and jelly sandwich can last for about 1-2 days if stored in the refrigerator. After that, it may start to spoil and should be discarded.
According to Butterball's website, an unopened turkey can be kept in the freezer for up to 2 years. Use a deep freeze freezer that is not frost-free. Frost-free freezers go through defrost cycles which have temperature fluctuations that could cause freezer burn.
A peanut butter sandwich can last for about 1-2 days at room temperature before it may start to go bad. It is best to store it in the refrigerator to extend its shelf life.
