Frozen thawed question

[scales.jp]

I know that wild monitor lizards and other reptiles thrive on decomposing carcasses, but how about feeding your snakes with anything that isn't quite "fresh"?

I'm asking because yesterday there was a mix up with my delivery of frozen rats, and they were sent out via standard shipping instead of chilled (delivery time was 24 hours door to door). Whatever the reason, they were not in a frozen state when they arrived.

I was a bit (very!) annoyed as I had paid extra for the chilled service, but as the rats were soft and my snakes were out and about searching for food, I decided to take a couple out to use before storing the rest in the freezer. It wasn't until after feeding that I began to think about whether or not there could be a health risk for my snakes.

I'll contact the supplier today to find out exactly what happened (they also sent the package to my home address, after I had specifically requested it be delivered to my work address).
