The constantly growing world population and the altered consumption pattern have considerably increased the demand for more, and more refined, food, particularly that of animal origin. Altered methods of production, highly concentrated froms of animal husbandry but also the resulting increase of the need for the cheapest possible materials for the mixed feed industry, the more rapid and greater transport facilities, the markedly increased trade in animals and particuarly in products originating fromthese animals, they all involve an increased risk of the import and outbreak of animal disease. The increased use of animal drugs, production-increasing agents and pesticides involve the danger of injurious residues being left in products of animal origin as a result of the comulative factors in animals. Therefore, the entire chain of production, beginning at the earliest possible stage, should be closely supervised. Supervisotry programmes of the Chief Veterinary Inspectorate of the Ministry of Health and of the Veterinary Service are, in a manner of speaking, the search-lights which, thanks to the refined methods of analysis developed by research workers, are able to detect and point out failings and deficiencies. An anticipated amendment of the Livestock Breeding Act, an anticipated replacement of the Antibiotics Act and a regulation forming part of the Statutory Trade Organization are designed to make it possible to respond more promptly to these signals.
