Not using aluminium can help you prevent botulism from baked potatoes
If you still want to wrap them in aluminum for baking, reserve this practice for personal use at home. Be sure to remove the foil from the potato directly after baking, this will help to prevent botulinum bacteria from growing inside the moist, oxygen free environment the aluminum provides.
