Improve Milk Quality Through Hygienic Milking Procedures in Dairy Farms
High-quality milk production is essential for a successful dairy business and the food processing industry. Poor milking hygiene and unclean practices can lead to milk contamination, threatening both food safety and dairy profitability. As a leading food processing consultant and dairy plant design expert, we highlight below the essential milking procedure practices to ensure safe, clean, and high-quality milk.
Common Causes of Milk Contamination
Understanding the sources of contamination helps implement effective food safety and clean milk production strategies. These causes fall into four broad categories:
- Animal-Related Issues: Unhealthy animals or unclean udders
- Milking Personnel: Poor hygiene, dirty hands, or clothing
- Milking Process: Incomplete milking, unclean equipment
- Environmental Factors: Unsanitary animal housing and surroundings
Essential Milking Procedures for Clean Milk Production
1 Animal Cleanliness
Maintaining animal hygiene is vital. Dairy animals must be:
- Regularly washed, brushed, and groomed
- Especially clean before milking
- Shaved around the hind legs, udder, and tail to prevent dirt in milk
This is particularly crucial for buffaloes, which often carry mud and debris.
2 Cleanliness of Utensils and Milking Personnel
Utensils:
- Use stainless steel, non-rusting vessels with narrow mouths
- Sanitize with a 200 ppm chlorine solution or approved food-grade sanitizers
- Avoid utensils with crevices or dents
Milking Staff:
- Must wear clean clothes and head coverings
- Wash hands thoroughly with soap and antiseptic solution
- Avoid bad habits: spitting, eating, or smoking during milking
- Regular medical checkups are essential for milk handlers
3 Animal Health Management
- Routinely inspect animals for mastitis or infections
- Isolate and treat affected animals
- Never mix milk from infected animals with bulk milk
- Follow proper milking order (healthy first, infected last)
4 Clean Milking Environment
- Clean the milking area, gutters, and floors before each session
- In muddy areas, sprinkle water to minimize dust
- Ensure proper ventilation and drainage in the housing area
Best Practices to Ensure Quality Milk Production
1 Animal Management
- Test new animals for tuberculosis and brucellosis
- Quarantine before adding to herd
- Clip hair and clean udders with warm chlorinated water before milking
2 Milker Hygiene
- Milkers must be disease-free, with short nails and proper attire
- Hands must be washed thoroughly before milking
- Caps and clean uniforms should be mandatory
3 Utensil Sanitation
- Use smooth-surfaced, dent-free utensils
- Clean with detergent-sanitizer combinations (e.g., sodium carbonate + iodophores)
- Avoid wide-mouth containers that increase contamination risk
4 Standardized Milking Process
- Always complete milking
- Remove foremilk (contains higher bacterial count)
- Use full-hand, dry milking technique
- Test with strip cups
- Cool milk immediately to below 5°C on-site
5 Sanitary Dairy Housing and Environment
- House animals away from sewage or stagnant water
- Provide proper ventilation, drainage, and sunlight
- Maintain at least 500 cubic feet per cow
- Regular lime washing and fly control measures
- Ensure dry bedding and smooth feed mangers
6 Additional Best Practices
- Maintain quiet surroundings during milking
- Encourage speedy, uninterrupted milking
- Keep feeds and weeds away from milking area
- Ensure regular manure removal and insect control
- Implement incentive-based hygiene reward plans
