Do I have to peel red potatoes before baking them? I recently made some potato wedges in the oven. I shared this recipe with my relative, who admonished me for not properly peeling the red potatoes before baking them.

She claims that there are disease and viruses that lie on the skin, so peeling it will get rid of it.  I bake it, so I assume that even the high heat in the oven would kill bacteria and germs. And besides that, I make sure to wash potatoes thoroughly before cooking them.

Am I in the wrong here? Should I have properly peeled the potato wedges before baking them? Personally I feel they add more flavor, and from all the pictures on the recipes online, it seems they also do not peel it.
No peeling is needed. 

A good wash and proper cooking will handle all of your food safety needs.
