Housekeeping job

Has anyone ever worked as housekeeping in an assisted living ? I want to apply for a job for that but Idk how nasty it will be ? I have OCD so it probably isn't the best job but I need a job and I don't have experience this will be my first job ever but with my OCD Idk like are these the kids of old people that makes messes with their poop if that makes sense? I hear stories of old people smearing their poop on themselves and the walls or pooping their sheets etc. And I don't Wana clean poop I can deal with the cleaning of overall their apartment and their bathrooms but when it has to do with poop with my OCD I will probably have like an anxiety attack . Anyway has anyone ?
