absolutely. if you defrost foodstuff in microwave, keep it refrigerated until you cook it.
On what is the temperature danger zone
It is best to err on the side of caution and throw away those vegetables. Bacteria can start to grow on food very quickly when left out.
Once thawed, the food should be cooked properly. Once cooked, the food can be eaten hot, or quickly cooled and put into a fridge to be eaten in a day or two. The food should not be refrozen once thawed.
You should never re-freeze frozen food once it has thawed. You can refrigerate it briefly, for a few hours.
The answer would vary with the type of food. For bread, for instance, the microwave is the worst; it gets all soggy. Many other foods, however, would be fine thawed by microwave. Potentially hazardous foods, like meat and seafood, should not be left on the counter to thaw.
It isn't generally safe to refreeze raw food. This is especially true for chicken, which is contaminated with salmonella at scary-high rates. If the chicken has thawed, it isn't generally safe to refreeze it and eat it later. This is especially true if it is thawed in room-temperature water rather than being thawed in the refrigerator. Once thawed, the chicken should be cooked fairly quickly. Once cooked, it can then be frozen for later consumption.
If the microwave is not energized, then the food will spoil. If the microwave is energized, then the food will burn.
Yes.
It is best not to re freeze thawed food. However if you cook the thawed rhubarb first, and allow it to cool you can then freeze the cooked rhubarb.
A microwave thawed piece of beef can be ok to eat after 3 hours of leaving out if the meat is kept at a cool temperature while it is out. The meat will need to be cooked until the internal temperature reaches 165 degrees Fahrenheit or more.
You can freeze it or refrigerate it.
Depends on the way you cook it. Or if it is frozen solid or thawed out at all. 7 minutes for frozen solid. 2 and a half minutes for thawed. Test the burger afterward to see if the burger is fully cooked
If the food has been thawed under refrigeration and has not started to spoil, food can be safely refrozen. Partially thawed can be refrozen, too. But the extra freeze-thaw cycle will cause degradation of quality. It might be better to cook the food, then freeze it.
