The construction must be smooth, durable and easily cleanable inside and out.

(2) A hoist of 2,000 pound capacity, capable of lifting a beef carcass to a height that enables the carcass to clear the ground for bleeding and evisceration. This hoist must extend outward from the truck body. If a beef spreader is included as part of the equipment it must be of suitable construction.

(3) A sterilizing tank constructed of smooth, cleanable, impervious and durable material, large enough to allow complete sanitizing of tools used in the slaughter operation.

(10) No animals other than scalded and dehaired hogs, and defeathered meat food birds, and carcasses exempted under subsection (8) of this section may be dressed and transported with the hide on.

(11) Viscera of all meat food animals and meat food birds must be separated from the carcass at the time of slaughter on the premises where the animal is slaughtered. Feet must be removed from all meat food animals, except hogs, when scalded, and the head shall be removed from beef on the premises where it is slaughtered. Feet and metatarsus must be removed from meat food birds.

(12) All material produced through the slaughter activity, such as inedible offal and hide that may cause the slaughter area to become insanitary, must immediately upon completion of actual slaughter of the animal, be removed from the slaughtering area and disposed of in a sanitary manner. This is the licensee's responsibility.

(13) Meat food birds may be slaughtered by a custom farm slaughterer or custom slaughter establishment but not by a licensed custom poultry processor without prior approval by the director.

(14) Inedible offal may be only transported by a mobile custom slaughtering establishment under the following conditions:

No other animal may be slaughtered by the licensee on the premises, farm or ranch, owned, rented or in any way controlled by ((him or her))themselves or by members of ((his or her))their immediate family. Licensees under this section may slaughter more than one animal only if the animals have been in ((his or her))their possession more than ((sixty))60 days.

(16) Whenever a licensee has reason to believe that a meat food animal or meat food product is unwholesome as defined in these rules, ((he or she))they must require an examination and declaration of wholesomeness by a licensed veterinarian before proceeding with slaughter or with processing of the carcass.
