I know your question was about germs and you got plenty of feedback already. For what it’s worth I agree with the tenor that you are right to be bothered.
However, am far more concerned by the water leak. It looks like you have hoisted wooden ceilings. You need to get the leak fixed ASAP and have someone check the joists are still ok. Water damage like this can rot the wood and a full bathtub can be heavy enough to break through the ceiling. This almost happened in my parents house.




I’m sorry. That really sucks. I hope you can move out soon and to a place that you can keep clean and safe.
