I wouldnt risk feeding freezer burnt rodents to my pythons.....just in case, not worth it. I personally wouldnt eat anythin that was freezer burnt therefore none of my animals do either
In the first two comments there's already a contradiction!!! Unbelievable...
Sorry Rosemary, but i have no idea where the risk factor comes from!
What is freezer burn would be the first question to ask...
So I strongly recommend you look up freezer burn, this is a link to the Wiki on freezer burn:
http://www.loc.gov/rr/scitech/mysteries/freezerburn.html
This site explains freezer burn as the loss of water molecules from a meat sample and hence the patchyness.
Forensick explains that it is harmless to humans, but may taste a little funny.
Dehydrated food is commonly eaten by all on this planet, and is in fact a way we preserve some of our foods.
I wouldn't hesitate to suggest it is perfectly safe to feed freezer burnt rats to your snake. They can do no harm, there is no risk (unless the rat is still frozen) based on what you're telling us.
I myself have eaten freezer burnt products with no ill effect
Cheers!
