A bracket system that allows a drop shield to be added to a prior art main viewing panel of a food guard. For instance, an existing food guard system can be modified to include a drop shield without having to make a permanent modification, or replacement, in order to close off “reach in” access to food stored beneath the food guard system. The system also reduces or eliminates any gap beneath the main viewing panel of the food guard and the upper edge of the drop shield.
