Item 14r

PROTECTION FROM CONTAMINATION

REQUIREMENT: Milking and milkhouse operations, equipment, and facilities
shall be located and conducted to prevent any contamination of milk, equipment,
containers, and utensils. No milk shall be strained, poured, transferred, or stored
unless it is properly protected from contamination.

After sanitization, all containers, utensils and equipment shall be handled in such
a manner as to prevent contamination of any product-contact surface.

Vehicles used to transport milk from the dairy farm to the milk plant, receiving
station or transfer station shall be constructed and operated to protect their
contents from sun, freezing and contamination. Such vehicles shall be kept
clean, inside and out, and no substance capable of contaminating milk shall be
transported with the milk.

Public Health Reason: Because of the nature of milk and its susceptibility to
contamination by disease producing bacteria and other contaminants, every effort
should be made to provide adequate protection for the milk at all times. This
should include the proper placement of equipment so that work areas in the
milking barn and milkhouse are not overcrowded. The quality of any air which is
used for the agitation or movement of milk or is directed at a milk contact surface
should be such that it will not contaminate the milk. The effect of sanitization of
equipment can be nullified if the equipment is not protected after sanitizing. To
protect milk during transportation, delivery vehicles must be properly constructed
and operated.

Inspectional areas of emphasis and special problem areas may be:

1. This item pertains to the protection of the milk supply from contamina-
tion by adulterants including, bacteria, drugs and chemicals.

2. When there is milk in the bulk tank, all openings must be protected or
capped to prevent the entry of contaminants. This includes, but is not
limited to CIP recirculating pumps and hoses that are permanently
affixed to the tank, lids and covers, CIP chemical wash units, etc. This
