Refreezing previously raw food
No, you should certainly not refreeze food that has already been defrosted. But, there is a small loophole here. It is not a loophole, once it has been stated you will see that it is pretty obvious. Firstly, the reason why you cannot refreeze food that has been thawed is that this allows bacteria to come back to life and grow. Then if you go ahead and freeze it, then the cycle is just being compounded meaning that when you eventually do eat it, there will be a whole lot of bacteria thriving in it.
But, what happens if the food was raw and then you cooked it. This mostly applies to meat, chicken, and fish. These foods are generally bought fresh and then tossed in the freezer raw. Which is completely okay. Then they are taken out and thawed. Another thing which is fine. What is not fine is refreezing this raw food. What you can do, however, is to cook the food and then refreeze it. The cooking process will kill any bacteria, therefore, making it safe to be tossed in the freezer again. It is unclear as to who would freeze a cooked steak, but it is possible if you are that way inclined.
