Food safety is so important & the question about what to do with leftovers always comes up. How long can cold food be left out of the fridge? Do you put hot food right into the fridge or let it cool on the counter? How long do leftovers keep in the fridge? Can you re-freeze leftovers? Lots of questions. I worked in a grocery store for a while & had to take a food safety course so I am familiar with most of this info..but I did find out things i didn’t know before.
