buried food

[new2tegus]

So my tegu ate a mouse he buried, and I thought I got everything out of his cage. So my question is how worried should I be. That was his first time he's done that, so I assumed he ate it. I know it has bacteria in it, and our stomachs have mechanisms to break down these things, as do theirs. Am I alone, or has this happened to anyone else? Thoughts or suggestions would be great.
