📌 Cold storage units help preserve the quality of sensitive products like food and medicine. But keeping things cold isn’t enough—regular cleaning and strict hygiene are just as important. How often should cleaning be done? What rules apply? Let’s take a closer look.
✅ 1. Why Cleaning Matters: Risks of Poor Hygiene
Microbial growth: Although slowed down at low temperatures, microbial activity doesn’t stop entirely—especially in fresh produce, meat, or dairy storage.
Odor contamination: Unclean environments can develop unpleasant odors that may affect all stored items.
Slip hazards: Leakage combined with freezing can lead to ice buildup, increasing the risk of workplace accidents.
Legal requirements: Food safety systems like HACCP, ISO 22000, and GHP demand documented and periodic cleaning routines.
🧼 2. How to Clean a ColdStorage Facility
Daily Cleaning
Floor checks: Look for spills, leaks, or ice formation.
Doors and seals: Clean condensation and debris around gaskets.
Shelves and surfaces: Wipe with food-safe sanitizer to avoid cross-contamination.
Weekly Cleaning
Walls and ceiling surfaces: Remove dust, mold, or residue with approved disinfectants.
Drainage systems: Even if unused, inspect and clean regularly to avoid clogs and odors.
Monthly/Periodic Cleaning
Cooling fans: Clean dust buildup to maintain energy efficiency.
Air filters: Replace or wash for optimal airflow and cleanliness.
Lighting fixtures: Dust and moisture should be wiped away regularly.

🛡️ 4. Hygiene Standards & Food Safety Regulations
Applicable Standards
HACCP (Hazard Analysis and Critical Control Points): Hygiene plans must be documented and traceable.
ISO 22000: Requires daily cleaning logs and validation.
GHP (Good Hygiene Practices): Emphasizes worker, equipment, and facility hygiene.
Staff Hygiene Rules
Only trained personnel should perform cleaning.
Gloves, masks, and hairnets must be worn.
Products should be covered or removed before cleaning begins.
Preventing Cross-Contamination
Separate tools for “clean” and “dirty” zones.
Use different cleaning sets for rooms at different temperatures.
Avoid contact between chemicals and stored goods.
