The food could be a problem, I know it's hard to find any good food for dwarf hams in the US but I think Higgins vita garden is recommended as the best, if I'm mistaken hopefully someone there can correct me but I'm pretty sure that's the one you need.

Any sign of blood is a concern, can you tell where it came from? It is possible she scratched herself but if you see more & aren't sure where it's coming from then you need to get her checked by your vet.

Don't overdo the cleaning, disinfectant is only needed if your hamster is sick & not always then, if you over clean & remove all her scent she will be peeing & scent marking more of the cage. Just spot clean pee when you find it & only clean anything else when it really needs doing.
