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?
The ISO/TS 22002-4 standard specifies requirements for prerequisite programs (PRPs) to assist in controlling food safety hazards in the manufacture of food packaging. It is a critical component for organizations seeking FSSC 22000 certification in the packaging sector. Top Checklist Categories for ISO/TS 22002-4
A comprehensive checklist typically covers these primary areas to ensure hygiene and operational safety:
Establishment & Layout: Evaluation of the workspace, including internal structures, workspace flow, and the separation of raw materials from finished products to prevent cross-contamination.
Utilities & Waste: Monitoring air, water, and energy supplies, alongside strict protocols for waste management and disposal.
Equipment Suitability: Ensuring all machinery is designed for easy cleaning and maintenance, and that it is made from materials safe for food-contact packaging.
Management of Purchased Materials: Verification of incoming materials and a robust system for supplier approval and monitoring.
Measures for Prevention of Contamination: Includes physical, chemical, and biological hazard controls, as well as strict allergen management.
Cleaning and Sanitizing: Detailed schedules for cleaning facilities and equipment, including the validation of cleaning effectiveness.
Pest Control: Documented programs for inspection, monitoring, and the safe use of pesticides within the facility.
Personnel Hygiene: Requirements for staff facilities, protective clothing, and health monitoring to prevent human-borne contamination. iso ts 220024 checklist top
Rework & Product Withdrawal: Procedures for handling non-conforming products and effective recall mechanisms.
Storage and Transport: Maintaining appropriate conditions during storage and shipping to preserve the integrity of the packaging material. Key Documentation
For a successful audit, your checklist should verify the existence of: A formal Hazard Analysis for packaging.
Documented Standard Operating Procedures (SOPs) for each PRP. Training records for employees on food safety and hygiene.
The ISO/TS 22002-100 framework can also be used as a reference to consolidate shared PRPs across different sectors.
For the next two hours, they moved through the checklist like surgeons.
Maya felt the floor tilting. Two hundred jobs. Her own future. All of it pinned to a checklist she had inherited from a man who quit.
Then, at 11:15 AM, Elena stopped in front of the raw material intake bay. The checklist’s “top” section had one final, brutal line:
7.5 – Has top management established a culture where food safety is prioritized over production targets?
Leo had followed them silently. Now he spoke. “Look, we make plastic cups. It’s not rocket science. We’ve never had a real problem.”
Elena turned. “The standard doesn’t care about history. It cares about systems. Last week, you ran a batch of non-food-grade regrind through a line that wasn’t cleaned afterward. Production needed the line. Your supervisor told me so.”
Leo’s face went red. “That’s hearsay.”
“It’s on the security footage,” Maya whispered. “I saw it last night. I was going to tell you, but…”
Elena closed her binder. “That’s a critical nonconformity. Certification denied.”
You are only as safe as your suppliers. This is a top area for audit non-conformities.
Use this checklist to assess your current compliance level. For each item, mark: Compliant (C) / Partially Compliant (P) / Non-Compliant (NC).
The ISO/TS 22002-4 checklist is your roadmap to a robust Prerequisite Programme. It is not a one-time exercise but a living document.

Title: The Top of the Checklist
Maya stared at the screen. The document title read: ISO/TS 22002-4:2013 Pre-Requisite Programme Checklist – Food Packaging Manufacturing.
“The Top,” her boss, Mr. Calloway, had called it that morning. “Just run the top of the checklist, Maya. It’s a small audit for a small client. How hard can it be?”
He didn’t understand. The “top” of this checklist wasn’t about airlocks or glass policies. It was Clause One: Construction and condition of buildings and facilities.
Maya was the Food Safety Manager for "SealFresh Packaging," a mid-sized plant producing foil seals for yogurt cups. They had just landed a contract with a major baby food company. The pre-audit was tomorrow. And the technical specification they had to meet? ISO/TS 22002-4 – the technical specification for prerequisite programs specifically for food packaging.
She printed the 18-page checklist. On physical paper, the top line wasn't a box to check. It was a warning.
1.1 Exterior Location and Grounds The facility shall be located in an area free from flooding, pests, and potential chemical/biological contaminants.
Maya grabbed her flashlight and hard hat. She walked to the back dock, the part of the plant no one talked about. Beyond the chain-link fence, a small stream ran along the property line. It had been dry for ten years. But last week’s freak storm had turned it into a muddy trickle.
She knelt. There, in the mud, were footprints. Not human. Hoof prints. Deer. And a torn, grease-stained fast-food wrapper that had washed down from the highway culvert.
Her stomach dropped. Clause 1.1 wasn’t about the building. It was about the zone of control. The deer carried E. coli. The flood risk meant potential for standing water. The wrapper meant potential for pests.
She called maintenance. “Frank, that drainage ditch by the back fence – when was it last dredged?”
“Dredged? Maya, we haven’t touched it since ’08.”
Maya looked back at the top of her checklist. She had a choice. She could lie. She could note “N/A – no recent flooding.” The client would never walk the back fence. Or she could do the job.
She took a deep breath and wrote in red pen: NON-CONFORMITY. Standing water risk. Wildlife intrusion evidence. No current pest control buffer. Requires immediate excavation and gravel fill.
She walked to Mr. Calloway’s office. “We have a top-line failure,” she said, placing the checklist on his desk.
His face went pale. “The baby food contract?”
“Will be canceled if we don’t fix it,” she said. “But it’ll be canceled for sure if we ship seals contaminated with flood-borne pathogens.” Part 3: The Checklist’s Secret For the next
He stared at the red ink. Then he did something she didn't expect. He smiled. “Alright. Call the excavator. Cancel tomorrow’s audit. Reschedule for next month. And Maya?”
“Yes?”
“From now on, we always start at the top.”
She nodded. Because she knew: in food safety, the most important part of any ISO/TS 22002-4 checklist isn’t the validation data or the HACCP plan. It’s the ground beneath your feet. If the top fails, everything underneath it is just paperwork.
ISO/TS 22002-4:2013 (and the updated ISO 22002-4:2025) specifies the Prerequisite Programs (PRPs) for food safety in the manufacture of food packaging.
