No food intended for human consumption shall be deposited or
allowed to remain within a distance of two feet above the surface
of any sidewalk, street, alley or other public place or the floor
of any building, where exhibited, unless the same shall be so contained
in boxes or other receptacles as to be protected from dogs and other
animals and their excretions. This provision shall not apply to fresh
fruit and vegetables which are ordinarily cooked or peeled before
using, and which are so wrapped, covered or enclosed as to be reasonably
protected from contamination by dust, dirt, insects or otherwise.
