I accidentaly switched my freezer off for a week.  This lead to spoilage of food, pool of blood inside freezer etc.  Trays are unremovable and difficult to clean.  I have thrown everything away and tried cleaning with baking soda, bleach etc but smell hasn't fully gone.  I'm assuming its just the smell of blood and I don't want to buy a new freezer straight away. If I freeze food in the meantime 1. will it absorb odours? 2. If it does will the food be safe to eat? 3. Can you suggest how else I can clean the freezer or should i go and buy a new one?  Thanks 
Not worth the risk, just throw it out.  There's no way to tell whether the smell was absorbed, or comes from bacteria in the food itself.
