The water used on dairy farms must be potable, meaning it is safe for human consumption and free from harmful microorganisms and chemicals. This water should come from a protected source and be regularly tested, especially when it is drawn from wells or other private supplies. Water points must be located so there is no risk of contamination from livestock, manure, or human waste. Clean water is required not only for drinking, but also for washing equipment, cleaning floors, and maintaining personal hygiene in milk-handling areas.
In areas without access to public sewerage systems, proper waste disposal becomes even more important. Human waste and floor washings from milk-handling areas should be directed into well-designed septic tanks or cesspools that are regularly maintained. Poorly managed waste systems can leak or overflow, creating serious health risks and contaminating nearby water sources. Clear separation between waste disposal systems and milking facilities helps prevent the spread of disease-causing bacteria.
Manure management is another critical factor in farm sanitation. Manure should never be allowed to accumulate near areas where milk is handled or stored, as it attracts flies and harbors harmful microorganisms. The most effective disposal method is spreading manure in thin layers over pastures, where it can decompose naturally and enrich the soil. Modern farms increasingly follow nutrient management plans to ensure manure is applied at appropriate rates and times, reducing environmental pollution while maintaining cleanliness.
Insect control is also essential in milk-handling areas. Flies, which can carry bacteria from waste to milk, may be controlled through flytraps that use entrapment liquids, electric fly killers, or approved chemical agents. Other pests, such as cockroaches, may require the careful use of approved insecticides in accordance with safety regulations. Integrated pest management practices, which combine sanitation, monitoring, and targeted treatments, are now widely recommended.
Clean facilities and healthy personnel are equally important. The walls and floors of milking areas should be smooth, easy to clean, and kept free from dust and dirt. Adequate ventilation helps reduce moisture and airborne contaminants. Workers involved in milk handling should be in good health and free from intestinal diseases. Flush toilets should be provided in areas that do not open directly into milking rooms, and hand-washing and sanitizing facilities must be readily available. Before milking begins, milkers should thoroughly clean, sanitize, and dry their hands to minimize the risk of contaminating the milk.
By maintaining clean water supplies, effective waste management, insect control, and strict personal hygiene, dairy farms can ensure milk is produced safely and remains wholesome from the cow to the consumer.
