Is it a health hazard to keep pet budgies (birds) in your bedroom?

I have two budgies that i keep in my bedroom. I change there newspaper flooring daily, although seeds and feathers and bird poo acilates under the tray for weeks. Is this bad for my health? Can like ingesting dried budgie poo cause diseases? I have kept them there for two years and so far I have not noticed any major health changes but Im still not sure if I should keep them there.
