Veterinary public health implications of U H T processing of milk.

The introduction of U H T treatment of milk into South Africa raises problems for local public health authorities controlling milk hygiene in their respective areas because of the legislation concerning milk produced and sold for various purposes. It is essential that the raw milk supply be derived from healthy cows with healthy udders, and be produced under sanitary conditions. Uniform control standards are necessary for U.H.T. milk and other forms of milk supplying throughout the Republic. Uniformity is also desirable for efficient local authority veterinary health services. The progress of veterinary control and supervision of Johannesburg's milk supply is discussed to indicate what has been achieved. There is need for a national scheme for controlling mastitis. Tests for the purchase of milk on quality must include tests for udder health by regular electronic cell counting of raw milk sources. Appropriate mastitis control incentive or penalty schemes for milk producers should be instituted.
