At 4:47 PM, Elena Okafor reopened her binder.
The drains in Zone 2 had been acid-cleaned and photographed. The air filters were replaced—Maya found spares in a forgotten storage room. Leo, red-faced but silent, walked every line supervisor through a retraining session he wrote himself. The security footage of the regrind run was preserved, logged, and a corrective action was filed: “Production halt protocol reviewed – no future exceptions.”
The owners authorized $200,000 in emergency repairs via a conference call.
Elena walked the plant one last time. She checked the “top management” section again.
7.5 – Culture of food safety prioritized over production?
Evidence: Plant director halted production for 3 hours for unplanned maintenance. Interim QM documented real-time corrective actions. Ownership approved funds within 90 minutes. Status: CONFORMING.
She signed the checklist.
“Conditional certification,” Elena said. “Three months to close the remaining minors. Congratulations, ApexPak.”
Leo shook her hand stiffly. Then he turned to Maya.
“You’re not fired,” he said. “You’re promoted. My job, if you want it. I’ll be in maintenance where I belong.”
Maya looked at her tablet. The checklist was green now. But she knew the real work was just beginning.
At the top of the document, she typed a new note:
“ISO/TS 22002-4 is not a test. It’s a mirror. Today we looked. Tomorrow we improve.”
She smiled. Then she went to check the drains again.

Master the ISO/TS 22002-4 Checklist: Your Top Priorities for Food Packaging Safety
If you're in the food packaging industry, you know that safety isn't just about the food itself—it's about the materials that touch it. ISO/TS 22002-4 (often used alongside FSSC 22000
) provides the specific requirements for Prerequisite Programs (PRPs) to control food safety hazards during the manufacture of packaging.
Whether you are preparing for an audit or just tightening up your operations, here is a "top-tier" checklist of the essential areas you must master. 1. Facility Design & Environment
Your building must be more than just a shell; it must be a barrier against contamination.
Assess the surrounding area for potential contamination sources (e.g., nearby industrial pollution or stagnant water). Layout & Workspace:
Ensure the internal design follows a logical flow that prevents cross-contamination between raw materials, intermediate products, and finished packaging. Infrastructure:
Walls, floors, and fittings must be durable, easy to clean, and maintained to prevent the buildup of dust or moisture. 2. Utilities: Air, Water, and Energy What flows your facility is just as important as the facility itself. Air Quality: iso ts 220024 checklist top
Ventilation and dust extraction systems must be adequate to prevent airborne contamination. Compressed Air/Gases:
Any gases that come into direct contact with packaging must be monitored for quality and purity. Water Supply:
Water used in the manufacturing process (like cooling) must meet potable standards if it poses a risk to the final product. 3. Equipment Suitability & Maintenance Your machines should be assets, not hazards. Hygienic Design:
Equipment must be constructed from materials that don't leach chemicals into the packaging. Preventive Maintenance:
Keep a rigorous schedule for lubrication (using food-grade lubricants where necessary) and repairs to prevent physical contamination like metal shavings or oil leaks. 4. Raw Material Management Safety starts with your suppliers. Approved Suppliers:
Only purchase materials (resins, inks, adhesives) from suppliers that meet your specific food safety criteria. Incoming Inspection:
Verify that incoming materials are stored correctly—separate from chemicals and waste—to avoid absorbing odors or moisture. 5. Personnel Hygiene & Facilities The human element is often the hardest to control. Hygiene Standards:
Establish clear rules for handwashing, hairnets, and protective clothing. Facilities:
Staff areas like canteens and locker rooms must be physically separated from the production floor to prevent food or personal items from entering the manufacturing zone. 6. Contamination Prevention This is the "meat" of the ISO/TS 22002-4 requirements. Chemical/Physical Hazards:
Implement strict controls for glass, hard plastics, and chemicals used for cleaning or pest control. Pest Control:
Maintain a proactive system (traps, monitoring, and professional inspections) to ensure your facility remains pest-free. Cleaning & Sanitization:
Use a documented cleaning schedule for both the environment and the equipment. 7. Rework & Product Information Rework Control:
If you reuse scrap or trim, it must be handled, stored, and tracked to ensure it doesn't introduce hazards. Traceability:
Ensure you can track every batch of finished packaging back to the raw materials used.
As of late 2025, the technical specification has been updated to ISO 22002-4:2025
. While the core PRPs remain similar, the new version aligns more closely with modern Food Safety Management Systems (FSMS) like ISO 22000:2018. or a guide on how to transition to the 2025 version of the standard?
Introduction
ISO/TS 22002-1 is a technical specification that defines the requirements for prerequisite programs (PRPs) in the food industry. The standard is part of the ISO 22000 family of standards, which focuses on food safety management.
Preparing a Good Report: Top Checklist
To ensure you're on the right track, here's a checklist to help you prepare a comprehensive report:
I. Prerequisites (5.1 - 5.5)
II. Prerequisite Programs (6.1 - 6.5)
III. Food Safety Management System (7.1 - 7.6)
IV. Documentation and Records (8.1 - 8.4)
V. Internal Audits and Management Review (9.1 - 9.3)
VI. Continual Improvement (10.1 - 10.3)
By following this checklist, you'll be well on your way to preparing a comprehensive report that meets the requirements of ISO/TS 22002-1.
This essay focuses on ISO/TS 22002-4 , the technical specification that outlines prerequisite programs (PRPs) for food safety in the manufacture of food packaging
While ISO 22000 provides the broad framework for a Food Safety Management System (FSMS), it lacks the specific "how-to" for the shop floor. ISO/TS 22002-4 fills this gap, ensuring that packaging—which touches almost everything we eat—doesn't become a source of contamination. The Foundation of Packaging Safety
The core philosophy of ISO/TS 22002-4 is that food safety starts long before the food is processed. If a plastic film, glass jar, or paper carton is contaminated with chemicals or physical hazards, the food inside is compromised. This standard provides a rigorous checklist to prevent such occurrences by focusing on the manufacturing environment. Top Pillars of the ISO/TS 22002-4 Checklist 1. Establishment and Infrastructure
The checklist begins with the physical plant. It requires that the site is designed to prevent cross-contamination. This includes proper layout, internal structures that are easy to clean, and the management of "utilities" like air, water, and energy to ensure they don't introduce hazards into the packaging material. 2. Waste and Sewage Management
Proper disposal systems are critical. The standard mandates clear procedures for identifying, collecting, and removing waste. This prevents the accumulation of debris that could attract pests or lead to the accidental reuse of contaminated materials. 3. Equipment Suitability and Maintenance
Machines used to produce packaging must be designed for food-grade safety. The checklist focuses on "hygienic design"—ensuring equipment is easy to sanitize and maintain. It also covers the use of food-grade lubricants to prevent chemical migration into the packaging. 4. Management of Purchased Materials
Safety starts with the raw materials (resins, inks, adhesives). The standard requires a strict vetting process for suppliers. Manufacturers must ensure that every incoming material has a "Declaration of Compliance" stating it is safe for food contact. 5. Prevention of Contamination This is the "heart" of the checklist. It addresses: Microbiological contamination: Managing humidity and hygiene. Physical contamination: Controlling glass, hard plastics, and metal fragments. Chemical migration:
Ensuring inks and coatings don't "bleed" through the packaging into the food. 6. Cleaning and Pest Control
The standard requires documented cleaning schedules and a proactive pest management program. In a packaging plant, dust and insects are primary threats; the checklist ensures these are managed through regular monitoring rather than just reactive treatment. 7. Personnel Hygiene
Even though workers aren't touching the food directly, their hygiene affects the packaging. The checklist covers handwashing protocols, hairnets, and the prohibition of jewelry or personal items in production areas. Why It Matters
Implementing ISO/TS 22002-4 allows a packaging manufacturer to achieve FSSC 22000 certification
, a globally recognized mark of excellence. It moves a company from a "reactive" stance to a "preventative" one. By checking these boxes, manufacturers protect the end consumer, reduce the risk of costly recalls, and build trust with major food brands. Conclusion
ISO/TS 22002-4 is not just a list of rules; it is a blueprint for integrity in the food supply chain. By standardizing the environment in which packaging is made, it ensures that the "container" is just as safe as the "content." summarized bullet-point version of this checklist to use for an internal audit?

A comprehensive internal audit checklist for ISO/TS 22002-4 typically covers the following technical requirements to ensure food safety hazards are controlled: Establishment Infrastructure Environment & Location : Is the site located away from potential contaminants? Layout & Workspace At 4:47 PM, Elena Okafor reopened her binder
: Are internal designs, traffic patterns, and equipment placement optimized to prevent cross-contamination?
: Are air quality, ventilation, and water supplies monitored and treated as necessary? Waste and Equipment Management Waste Handling
: Are there documented procedures for waste removal and drainage? Equipment Suitability
: Is equipment designed for easy cleaning and maintenance (hygienic design)? Maintenance
: Are preventive and corrective maintenance schedules established and recorded? Operational Controls Purchased Materials
: Is there a selection and management process for suppliers of raw materials? Contamination Prevention
: Are measures in place to prevent microbiological, physical, and chemical contamination? Cleaning & Sanitizing
: Are cleaning schedules and concentrations for sanitizing agents documented and verified? Personnel and Hygiene Personnel Hygiene
: Are facilities for handwashing and changing available and used correctly? Product Information : Is labeling accurate to prevent consumer misuse? How to Write Up Your Checklist Results
When performing a write-up after an audit or for a procedure, follow these steps to ensure clarity and compliance: ISO - International Organization for Standardization Define the Scope
: Clearly state which part of the packaging manufacturing process is covered (e.g., "Extrusion and Printing for Food-Grade Films"). Align with Clauses
: Structure your write-up using the clause numbers of the ISO/TS 22002-4 standard (e.g., Clause 4.7 for Contamination Prevention). Identify Conformance : For each item, indicate (Compliant), (Non-compliant), or Detail Evidence
: Do not just check a box. List specific evidence, such as "Reviewed cleaning records for Line 4 dated March 2026." Draft Corrective Actions
: If a requirement is not met, define a clear, time-bound corrective action to address the gap. Use Plain Language
: Keep sentences short and use active voice to avoid misinterpretation by auditors or staff. ISO - International Organization for Standardization Related Standard Components : Provides the overarching management system framework. HACCP Plan
: Required alongside PRPs to manage critical control points. DNV - Global for a specific section, such as Contamination Prevention Supplier Management how-to-write-standards.pdf - ISO
ISO/TS 22002-4 is about evidence. "If it isn't written down, it didn't happen."
Maya Vasquez had three hours to save two hundred jobs.
She stood in the silent, stainless-steel heart of ApexPak’s food-packaging line, the air thick with the smell of sanitizer and ozone. In her trembling hand was a tablet. On the tablet was a single document: ISO/TS 22002-4:2023 Checklist – Top Section (Management Commitment).
Three months ago, ApexPak was a mid-tier family business making yogurt cups and takeout clamshells. Then came the recall. A competitor’s liner failed; a child got sick. Now every major retailer demanded a new certification by noon today. Without it, ApexPak’s contracts would vanish by 5 PM.
Maya wasn’t the quality manager. She was the interim quality manager—promoted after the old one quit, screaming about “unfixable rot.” She was 29, over-caffeinated, and drowning. She signed the checklist
But she had the checklist.
