You can't defrost then refreeze anything :)
Yes, but it isn't very good for you to eat it after.
its not bad
Only if the chicken has been cooked. It is not a good plan to refreeze raw meats. This will cause the meat to be less flavorful as well.
Possible, but not recommended due to possible bacteria growth and change in texture. However, if you defrost raw pork, then cook it, you may then refreeze it.
yes you can
It is not a good idea to refreeze raw fish. If it was thawed, it is not safe to refreeze it.
In my opinion, i believe yes, i have done this several times.we can defrost it if we want small piece of it .and keep the rest of pieces.Because when anything is frozen no external heat is mixed....
If it was thawed properly and was not going bad when refrozen, yes. But the quality will not be as good. Whilst I do not know if it is the same in Britain, in the US it is considered safe to refreeze raw chicken if it has been defrosted in a refridgerator, and has not been subsequently chilled for too long
Yes, you can thaw, cook, and refreeze chicken.
