Would I be a bad person for not confronting my supervisor about being unhygienic?

I just got a job at a cleaning company where we have contracts with all sorts of companies and cleaning their buildings. There is a really nice man training me. He takes dwell time with the disinfectants seriously. he's also very serious about not cross contaminating. Well, we wear gloves and last night he took out all the trash to the dumpster and with the same gloves, he turned off all of the light switches. I dont want people to get sick but im afraid of bringing it up to him.
