The dairy industry in the United Kingdom to-day is of a size which few, even of those working in the industry, fully realize. In this industry one must include milk production on the farm, the handling, processing and distribution of liquid milk, the manufacture of milk products such as butter, cheese, dried and condensed milk, the manufacture and distribution of feeding stuffs for dairy stock, the manufacture of dairy equipment and machinery and other minor ancillary industries. Including the dependents of those actually engaged in milk production or utilization, approximately 5 % of the total population of this country is supported by the dairy industry. In monetary values, the present annual turn-over, in liquid milk alone, considerably exceeds £200 million. Measured in volume of liquid milk consumed per head of the population—a value more easily translatable into the coinage of national health— no less than 31 gal. of liquid milk per head were consumed on the average by every individual in this country during 1949.

Commercial sodium hypochlorites, whether containing KMnO4 or not, are shown to be corrosive at 150 p.p.m. available chlorine and 40° C. to metals such as aluminium, tinned copper, nickel silver and cast stainless steel (18 Cr, 8 Cu, 3 Mo) which are used in dairy equipment. Hypochlorites containing KMnO4 when aged are potentially dangerous to wrought 18/8 stainless steel. The attack is by pitting and therefore especially dangerous to all the metals investigated, and, in general, increases with increase of time of exposure and temperature.Decay of sodium hypochlorite solutions results in conversion of NaOCl to NaCl and NaC103, which reaction is shown to follow a simple equation fairly closely in various storage conditions.Attack on metals by sodium hypochlorite can be efficiently inhibited by addition of sodium silicate, which has a specific action in addition to the effect exerted by increase of alkalinity. NaOH and Na2CO3 additions to the same pH are not so effective and increase attack on aluminium.Increase of pH from 9 to 10·5 by addition of Na2CO3 or sodium silicate reduces bactericidal efficiency of hypochlorites to the same extent.

1. Hypochlorite was allowed to react with glycine and with skim milk in various proportions, and the germicidal power of the resultant mixtures was determined.2. The results indicated that chloramino compounds formed by interaction of hypochlorite and protein or amino-acid have a definite but slow disinfecting action against Str. cremoris.3. The chloramino compounds did not appear to be more strongly germicidal at pH 9·5 than at pH 7·0 under the conditions of the experiments.

To hold the cost of products sold at a competitive level in face of rising prices, it is necessary that production costs be held to a minimum. The first major field of reduction of production costs is in labor costs. In order to get the most out of dairy equipment labor must be properly used. When the time requirements of a job are reduced by improving the method, the worker must be gainfully employed at some other assignment. There are beneficial changes which provide leisure, add to the comfort of the worker, and reduce the hazards of his work. Changes in plant equipment arrangement may be made even though they are not justified on a purely economical analysis. The paper presents principles, with applications, which can be followed in each plant to improve the work method and decrease time requirements.

Milking machine rubber care requires the same fundamental steps in cleaning as any dairy equipment: Immediate air-brushing with clean cool water, routine disassembly, bristle-brushing in a balanced dairy cleaner solution, reassembly, sanitizing with 185°F water, and storage. Boiling the rubber parts in a graniteware vessel containing a solution of lye (made up of two heaping teaspoonfulls of lye added to each quart of water) for fifteen minutes, cooling, and soaking for eight hours, removes butter fat, improves resiliency and milking efficiency, and promotes sanitary milk production.
