DD has turned the freezer off probably thinking it was the toaster I presume. She noticed last night when she offered to make tea and noticed the veg burgers were a bit defrosted. She said nothing and put them on to cook.
So this afternoon I got home and found the entire chest freezer defrosted. Everything is fully defrosted some of it is warm mush. 
Can I really not refreeze anything?
If it has been off since Monday night (I used chicken Monday night and it was still frozen) will any of it be safe to eat tonight?
Swears loudly
