Many food-safety controls depend on hygiene practices being performed consistently every day. When cleaning, people and material flows, pest control, and storage are managed separately, changes to a product or process can leave gaps. ISO 22002-100 can provide a starting point for organizing common prerequisite programmes.
Who it applies to and when to start
Organizations in food, feed, and related packaging supply chains can identify the applicable parts based on their industry role. Review PRPs when adding a site, product, production line, or people and material flow, or when updating an existing food-safety system.
Common business challenges
- Cleaning is signed off without checking the method or result.
- Allergen or material changes are not reflected in segregation and line-changeover arrangements.
- Maintenance, contractors, and visitors follow requirements that differ from production hygiene rules.
- Pest or contamination findings are addressed, but the root cause and site conditions remain unchanged.
Approach and applicable requirements
The ISO catalogue lists ISO 22002-100:2025 as a published prerequisite programme requirements standard for food safety. It provides a common basis for food, feed, and packaging supply chains and should be used together with the applicable sector part. It does not replace an ISO 22000 management system and Part 100 alone may not include all sector-specific requirements.
Possible topics include premises and facilities, utilities and flows, personal hygiene, cleaning and pest control, chemicals and foreign objects, allergens and cross-contamination, materials and storage or transport, maintenance, records, and routine review, connected to hazard analysis and control plans.
Support and work stages
Confirm the industry and document set
Organize products, activities, and sites. Confirm the relationship between common requirements and applicable sector parts and prepare a PRP comparison list.
Review site conditions along the flows
Review raw materials, people, waste, and finished-product flows for cross-contamination risks. Separate operational improvements from issues needing engineering work.
Test cleaning, maintenance, and hygiene practices
Check methods, responsibilities, frequency, and exception handling. Arrange handoffs between employees and contractors so records reflect actual work.
Review results and reconnect to food safety
Use appropriate observations, inspections, or tests to track PRP results and feed changes or nonconformities back into hazard analysis. Outputs may include site gaps, operating adjustments, and follow-up actions.
Information to prepare
Prepare product and industry categories, site and flow diagrams, hygiene and cleaning procedures, pest-control and maintenance records, material and storage or transport conditions, contamination incidents, and existing hazard analyses. Describe outsourced work and shared facilities so the review is not limited to production documents.
Assessing schedule and fees
Site size, process and product variation, current hygiene conditions, and improvement methods affect the schedule. Construction or equipment work, pest-control services, specialist testing, and technical validation of cleaning require separate scoping and fees.
Frequently asked questions
Does Part 100 alone cover every food-chain activity?
Confirm the applicable sector part and scheme requirements. Common requirements alone may not be sufficient.
Can we keep our existing cleaning and inspection forms?
Records may be retained if they address applicable requirements and reflect work actually performed. Add method, exception, and result information when needed.
Does a signed cleaning record prove effectiveness?
A signature records confirmation of performance. Effectiveness still needs an appropriate basis and cannot be judged by form completion alone.
Why review PRPs for a new product?
Ingredients, allergens, processing, or storage conditions may change contamination risks, so confirm that existing arrangements remain suitable.
Can this standard replace hazard analysis?
PRPs provide foundational conditions. Product and process hazard analysis and controls still need to be completed separately.
Is the applicable edition still a technical draft?
This page follows the published ISO 22002-100:2025. Confirm the relevant sector part and scheme edition during implementation.
