(1) All trucks, vehicles, and containers used for the collection and transportation of garbage to be prepared, cooked or otherwise treated to be fed to swine or other animals must be constructed of or lined with impervious material which prevents the escape of any fragments of garbage or of liquids. The garbage must be covered at all times in such a way that flies, insects, rodents, poultry, and other animals may not have access to it.
(2) All trucks, vehicles, cans, vats, bins, tanks, and other containers used for storage of garbage, either before or after such garbage has been prepared, cooked, or otherwise treated, must be constructed of or lined with impervious material and covered in such a manner that flies, insects, rodents, poultry, and other animals may not have access to the contents.
(3) All cans, vats, bins, tanks, tables, platforms, machinery and other facilities used for or in the process of sorting garbage prior to being cooked or treated must be constructed of or surfaced with impervious material so that they may be cleaned and disinfected. The floors of all areas in which such sorting is done must be constructed of concrete or other impervious material and properly drained so that they may be washed, flushed and disinfected. Sorting areas must be so located and constructed that flies, insects, rodents, poultry and other animals do not have access to uncooked garbage.
