Pork can in fact be refrozen, but you will need to make certain that it is still good and edible before you put in back in the freezer.

There are lots of people who defrost their meat and then for whatever reason need to put it back in. As long as the meat does not sit out for too long after it has been taken out of the freezer or refrigerator, you can feel free to put it back in until you want to eat it.

It will also be important to make sure that the pork you refreeze is cooked thoroughly when you are preparing it to be eaten, because the last thing you want is to eat pork that has not been cooked all the way.
