Show Sewage Dirposskl. Most of the diseases which may L9 carried by milk are due to contamination contamina-tion of that product by human agency. Typhoid, dysentery, scarlet fever, diphtheria diph-theria and septic sore throat are of human origin. Typhoid and dysentery are spread originally by contamination by human excreta, the others are spread originally by discharges from the nasal and throat passages, conset-quently conset-quently when these diseases are conveyed con-veyed through milk, it simply means that the milk has had added to it the excreta or discharges from the body of a person sick with one of these diseases dis-eases or a carrier of one of them. As a go-between, the house fly, which hatches in filth and feeds on the food we eat, Is n most dangetous insect enemy. The washing of excreta into water supplies, through the soil or on account of poor well curbing or other surface conditions, is an important means of spreading such diseases as typhoid fever and dysentery. Tlie handling han-dling of milk by unclean persons is also a source of danger. The remedy for these conditions Is the proper disposal of human excreta so that there can be no dagger of such contamination through the agency of flies, water supply, sup-ply, or human beings. Proper sewage disposal on dairy farms is a prelection not only to the consumer of milk but is of special importance im-portance in stopping the spread of epidemic epi-demic disease in the dairyman's own family. A typhoid case in a family will spread to other members of the same family unless great care is taken in properly disposing of the excreta from the patient. The importance of proper sewage disposal, especially on dairy farms, is. being strongly emphasized by the United States department of agriculture agricul-ture and the United States public heulth service. |
