Rotation and Stock Management

Effective inventory management is crucial to ensure product freshness and minimize waste due to expiration.

• First-In, First-Out (FIFO) System: This method ensures that the oldest stock is used or shipped first. Implement FIFO through proper labeling, organized shelving, and staff training. Rotate stock during every new delivery.
• Batch Tracking: Use a digital inventory system or manual log to track batch numbers and expiration dates. This enables quick recalls if needed and supports quality control.
• Regular Inspections: Conduct weekly visual and physical inspections of stored milk powder. Look for:
  • Clumping or hardening (indicative of moisture exposure)
  • Foul odors or discoloration (signs of spoilage)
  • Container damage or seal failure
  • Mold growth inside or around containers
• Shelf Life Considerations: Most milk powders have a shelf life of 12–24 months when stored properly. Always verify the manufacturer’s expiration date and avoid using expired product, even if it appears normal.

Best Practice: Designate a "quarantine zone" for newly received milk powder until it passes quality checks. This prevents accidental mixing with existing stock and ensures traceability.

Regular Cleaning and Sanitisation

Milk powder is a nutrient-rich medium that can support the growth of bacteria, yeast, and mold if exposed to contamination. A rigorous cleaning protocol is essential for food safety.

• Surface Cleaning: Clean and sanitize all contact surfaces—including shelves, bins, scoops, and conveyor belts—on a weekly basis using food-safe disinfectants (e.g., quaternary ammonium compounds or peracetic acid).
• Spill Management: Clean up any spills immediately to prevent clumping and microbial growth. Use dry methods (e.g., vacuuming with HEPA filters) to avoid moisture introduction.
• Pest Control: Seal entry points and conduct regular pest inspections. Rodents and insects can contaminate milk powder and damage packaging.
• Staff Hygiene: Train warehouse personnel in food handling hygiene. Require handwashing, use of gloves, and clean uniforms when handling dairy products. Prohibit eating or drinking in storage areas.
• Zone Separation: Store milk powder separately from non-food items, chemicals, or strong-smelling products to prevent cross-contamination and odor absorption.

Warning: Never use wet cleaning methods near open milk powder containers. Water or steam can cause rapid spoilage and create breeding grounds for pathogens like Salmonella and Enterobacter sakazakii, which are particularly dangerous in infant formula powders.

Additional Recommendations for Long-Term Storage

• Consider nitrogen flushing or vacuum sealing for long-term storage to minimize oxidation.
• Limit the frequency of container openings to reduce air and moisture exposure.
• Use desiccant packs inside large storage containers as an added moisture barrier.
• Conduct periodic microbiological testing of stored samples, especially for large inventories.
