Food Safety in School Canteens Assured with ISO 22000 Principles
Introduction
Millions of kids go to school canteens hungry and eager every school day. They assume that the food on the trays will be clean, healthy, and safe. There is, however, an intangible responsibility behind all that rice, sandwiches, or snacks — food safety management.
Over the past few years, there have been outbreaks of food poisoning attributed to inadequate hygiene, incorrect storage, or unskilled food handlers in various Nigerian schools and others around the world. What schools do not understand is that such occurrences are avoidable — and the best prevention option already exists: ISO 22000.
What ISO 22000 Really Means for Schools
ISO 22000 is a global standard that defines the needs for a Food Safety Management System (FSMS). It assists organizations in making food safe throughout all processes — from raw material procurement to consumption.
Most people think of big food producers when they hear ISO 22000, but it’s just as effective for educational institutions running school canteens or school meal programs.
Under ISO 22000, food safety is not a matter of chance — it becomes an organized system consisting of risk assessment, hazard control, personnel training, documentation, and ongoing improvement.

Why Food Safety in School Canteens Needs Serious Attention
Children are at greater risk from contaminated food than adults due to their developing immunity. A moment of canteen hygiene failure can result in widespread sickness.
Typical food safety issues within schools are:
- Insufficient temperature control for perishable foods
- Cross-contamination between raw and cooked foods
- Lack of hand hygiene among catering staff
- Use of untested suppliers
- Irregular cleaning and pest control
Case Example – Abuja (2022):
A nearby secondary school had a food poisoning outbreak after serving rotten meat pies that were not kept at a safe temperature. This incident compelled the school board to implement ISO 22000-based hygiene measures. Within six months, the school implemented defined procedures for temperature checks, supplier assurance, and cleaning schedules — with not a single incident reported since then.
How ISO 22000 Principles Can Transform School Canteens
Let’s see how the fundamental principles of ISO 22000 can be implemented in a school setting directly.
1. Leadership Commitment and Policy
Leadership engagement is the first step towards implementing ISO 22000. School administration needs to make a food safety policy, share it with everyone in the staff, and vow to provide them with the necessary resources.
Example:
A Lagos private school developed a “Healthy Lunch, Healthy Mind” policy. The principal signed off personally on ISO 22000 compliance, so both canteen staff and teachers knew their part in ensuring food safety.
This bottom-up approach instilled a culture where hygiene wasn’t only a kitchen responsibility — it was a school value.
2. Identifying Food Safety Hazards
Clause 6.1 of ISO 22000 highlights the identification of biological, chemical, and physical hazards.
In canteens at school, common risks are:
- Biological: Bacteria (Salmonella, E. coli) from raw or undercooked food
- Chemical: Cleaning residue or pesticide residue
- Physical: Foreign objects such as hair, glass, or pieces of plastic
Case de Tanganyique Réal (Ghana, 2023):
At a boarding school, students reported stomach upset after eating jollof rice. The investigation found that cooked rice was left at room temperature for four hours. Under ISO 22000, this was categorized as a biological hazard, leading to the introduction of hot-holding equipment and strict timing control.
3. Implementing the HACCP Plan
The core of ISO 22000 is the Hazard Analysis and Critical Control Point (HACCP) system. It entails the identification of critical points during handling where prevention, elimination, or reduction of hazards is possible.
Common Critical Control Points (CCPs) in School Canteens:
Process Stage | Potential Hazard | Control Measure |
Receiving ingredients | Contaminated raw food | Source from approved suppliers |
Cooking | Undercooked meals | Use temperature probes (≥75°C) |
Storage | Bacterial growth | Keep below 5°C |
Serving | Cross-contamination | Separate utensils for raw/cooked food |
By implementing HACCP principles, schools bring order out of chaos — every step becomes tracked, recorded, and traceable.
4. Competence and Training of Canteen Staff
ISO 22000 stresses staff competence (Clause 7.2). All canteen staff, from cleaners to cooks, need to grasp fundamental hygiene concepts.
Case Example – Enugu (2024):
A government secondary school collaborated with Maxicert’s ISO 22000 food safety training program to educate 12 canteen staff. Training included hand hygiene, waste segregation, and allergen control. Within two months, the school achieved quantifiable improvements in kitchen hygiene and adherence to food handling procedures.
Trained staff don’t just take orders — they make knowledgeable choices that safeguard students’ health.
5. Maintaining Clean and Safe Infrastructure
The setting in which the food is prepared sets the safety of the food. ISO 22000 mandates hygienic equipment and facilities (Clause 7.1.4).
Key School Requirements:
- Smooth, easy-to-clean surfaces
- Handwashing facilities within work areas
- Proper waste containers with lids
- Regular logs of pest control
- Functional thermometers and refrigerators
Example:
One Nairobi Montessori school carried out an audit on their premises with the sanitation checklist of ISO 22000. They found that one refrigerator had temperatures ranging from 2°C to 12°C. Upon replacement and assigning daily temperature recording, spoilage never re-occurred.
6. Communication and Documentation
ISO 22000 requires open communication — with suppliers, parents, and among the school.
Schools can keep:
- Supplier approval forms
- Cleaning and disinfection records
- Daily temperature logs
- Food sampling records
These records establish traceability. If a food problem occurs, the cause can be rapidly identified and remedied — preventing panic and loss of reputation.
7. Verification and Continuous Improvement
The best systems can also fail if they are not monitored. ISO 22000 mandates occasional internal audits, management reviews, and performance checks.
Case Example – Abuja (2023):
One school incorporated ISO 22000 internal audits with assistance from Maxicert’s food safety consultants. They conducted quarterly sanitation checks and random testing of foods. The school achieved a local government food safety excellence award within one year — demonstrating ISO 22000 is not theory, but quantifiable action.
Building a Food Safety Culture in Schools
Food safety does not stop with the kitchen staff. Everybody — teachers, students, and parents — is involved.
How schools can build a safety culture:
- Place hygiene posters and safety messages
- Have food safety addresses in assemblies
- Ask students to report dirty conditions
- Integrate safety queries in school competitions or projects
In one Nigerian boarding school, the principal implemented a “Hygiene Hero” award for canteen staff and students who showed best practices — a fun but effective method of making food safety consious.

Real-World Impact: A Case of Preventive Success
At a private school in Port Harcourt, one inspection even uncovered expired snack foods in the canteen storage. The management opted to put in place ISO 22000-based controls under the advice of a local consultant.
In six months, the school implemented:
- Expiry date tracking logs
- Weekly internal audits
- Supplier verification lists
- Monthly temperature checks
Not only were food safety concerns removed, but the school also reduced food waste expenditure by 18%. Perhaps most importantly, parents started to trust the canteen again — an invaluable plus.
