Would you have called parent out on this?

The parent likely didn't even think about all of the surfaces she was touching on the way out. All she was thinking about were Her hands and taking care of herself.

Assuming in a case like this it is ok to bring it to the parent's attention and when she offers to just do it outside say something about we have a daycare rule that all hands must be washed in the diaper area so that we don't contaminate everything else we touch. In other words make her embarrassed enough to go wash without it coming off negatively.

Personally in this case I would have told mom oh he just told me he pooped we will be right back and then I would have changed him and taken care of it all my way and then handed over the child. My bathroom/change area isn't far from the front door so it works well. Much prefer that over having a parent come in and do as you said and ruin everything I have in place.
