Looks like it could be rust. Even if it it’s, that’s not really a problem. You can probably get rid of the rust by cleaning the teapot a bit better next time.

I don’t see any problem with continuing to use it in the future. If you’re worried about microbes colonizing the place, remember two things:

1. When not in use, keep it empty and dry.
2. Clean it every now and then.

BTW, aren’t teapots usually ceramic?
