Can I store raw meat in the fridge after defrosting in the microwave? I had a frozen package of bacon. I only wanted to use half the bacon, but couldn't separate the frozen bacon strips, so I defrosted the whole package in the microwave. The bacon got quite warm - not fully cooked, but smelling like bacon. I used what I needed and put the rest in the fridge immediately. I'm planning on using the rest of the bacon in a few days. Is that a good idea, or should I just throw it away?
You can use it in a few days, that will be fine. Issues with food safety come into play largely when food is kept in the danger zone, around 40-140F for an extended time.

The texture of the bacon might not be quite as good since it's kind of like the second time you'll be cooking it.
