Midwife did not wash hands after changing diaper.

So, as the title says. It is our first baby. We were tired and still in hospital 3 days in. It's night shift. A new midwife on duty. We both are pretty tired to a point that my wife has high blood pressure. We want to feed the baby and baby won't accept the feed. We call in midwife who proceeded to help changing the diaper and then proceeded to feed the baby with bottle with same hands. I did not even realise it and by that time, she has already burped the baby, touched her chin, touched her cot and pretty much everywhere. When I pointed out she said she did not touch the poop and used 2 tissues. I am scared what if something already has been transferred. Although I will complain about her, is there anyway to make sure nothing has been transferred to baby and everything is ok ? Or do I need to wait for few days. It's 1.30 in night and I am really worried.
