Are Your Storage Practices Violating GMP Without You Knowing?

When it comes to Good Manufacturing Practices (GMP), storage is more than just putting products on shelves. Small oversights can lead to audit failures, contamination risks, and costly recalls. Many businesses unknowingly break GMP rules simply because they assume “storage is simple.”

Below is a checklist to help you spot and fix common GMP storage mistakes before they become a serious problem.

🚫 Common GMP Storage Mistakes to Watch Out For

• Inadequate Temperature Control

  • No consistent monitoring for cold rooms or freezers

  • Using non-calibrated thermometers or unverified devices

• Poor Humidity Management

  • No humidity checks in dry storage

  • Allowing condensation to form on walls or ceilings

• Direct Contact with Floors or Walls

  • Products stored directly on the floor instead of pallets

  • No clearance for air circulation against walls

• Mixing Incompatible Items

  • Chemicals stored near raw materials or finished goods

  • Food and non-food items kept in the same area

• No Stock Rotation System

  • Lack of FIFO (First In, First Out) or FEFO (First Expire, First Out)

  • Expired or damaged stock left in the storage area

• Weak Pest Control in Storage Areas

  • No pest monitoring devices or inspection records

  • Open packaging attracting insects or rodents

📋 Essential GMP Storage Requirements

• Segregation: Separate raw materials, in-process goods, and finished products

• Stock Rotation: Use FIFO or FEFO to prevent expired inventory

• Proper Positioning: Store goods off the floor and away from walls

• Environmental Control: Maintain and record correct temperature & humidity

• Pest Prevention: Install traps, monitor regularly, and keep records

• Safe Chemical Storage: Keep away from food-contact surfaces and packaging

🛠 Steps to Improve GMP Storage Compliance

• Conduct weekly internal storage audits

• Label and date all incoming materials

• Train staff on proper GMP storage protocols

• Maintain calibration records for measuring devices

• Review and update your storage SOPs regularly

• Establish a corrective action process for non-compliance

⚠ The Risks of Ignoring GMP Storage Rules

• Audit Failure: Non-compliance can delay or block GMP certification

• Contamination Risks: Improper storage can cause cross-contamination

• Financial Loss: Spoilage, recalls, and penalties can be costly

• Reputation Damage: Customers lose trust after quality issues

💡 Pro Tip: Even small storage errors can have big consequences. Regular monitoring and documented checks are your best defence against GMP violations.
