Description: Third part of a three part film produced by the Public Health Department of the Metropolitan Borough of Hackney looking at some aspects of food inspection. This part considers Milk Distribution. Some parts of the supply chain are visited and recorded including AS Stapleton & Sons supplying milk from Brooklands Dairy Farm, and retailers 'Richards Bros'. Various elements of the hygiene routines concerning dairy products are recorded including bottle cleaning, the use of a clarifier, the pasteurisation process and the use of a cold store.
