To mitigate bacterial presence in raw milk, stringent measures are crucial. Prior to milking, cows undergo thorough washing and sanitization of their flanks, udders, and teats. Large dairy farms often employ dedicated wash pens for this purpose. Milking equipment and utensils must be meticulously cleaned and disinfected using methods such as steam or chlorine solutions, ensuring a chlorine concentration of approximately 200 ppm for effective sanitation.
Upon collection, bulk milk tanks are subjected to rigorous cleaning processes. Manual cleaning involves washing with hot water and detergent, followed by sanitization using chlorine solutions. Alternatively, mechanical cleaning at higher temperatures enhances effectiveness, followed by the same chlorine sanitation protocol. Manual cleaning of tank outlets and exteriors is also essential to prevent external contamination.
Advanced cleaning techniques like Cleaning in Place (CIP) further streamline hygiene procedures. CIP systems utilize vacuum or pressure to automate cleaning, sanitizing, and rinsing of pipelines and bulk milk tanks, ensuring thorough sanitation without disassembly.
In summary, safeguarding milk quality hinges on comprehensive hygiene practices throughout the milk production and processing chain. By addressing potential sources of microbial contamination—from the cow's udder to milking equipment and storage tanks—producers uphold stringent standards that preserve the safety and integrity of milk destined for consumer consumption. These protocols not only adhere to regulatory requirements but also uphold consumer confidence in the quality and safety of dairy products.
