ISO 22000 Certification in Nigeria: Who Needs It, Steps and Typical Costs

ISO 22000 certification in Nigeria is a way for food businesses to prove that they run a documented food safety management system that follows the international standard ISO 22000:2018. It is voluntary under the standard itself, but supermarkets, exporters, caterers and multinational buyers increasingly ask for it. This guide explains what ISO 22000 is, who needs it, how it compares with HACCP, the steps to certification, how to choose a certification body, and what drives the cost. We do not quote prices, because they depend on your site and the certification body.

What ISO 22000 is

ISO 22000 is an international standard for food safety management, often called ISO 22000 food safety certification when a company passes an audit. According to ISO, it sets out the requirements for a food safety management system and can be used by any organisation in the food chain, regardless of size or product. That includes farms, processors, packers, transport and storage companies, caterers and equipment makers that touch food.

The standard combines three ideas. First, HACCP-based hazard control, which means finding what could make food unsafe and controlling it. Second, prerequisite programmes, which are the basic hygiene and good practice rules such as cleaning, pest control, supplier control and staff training. Third, management system and communication, which means leadership, planning, documents, internal audits and clear information flow with suppliers and customers. Because it follows the same high-level structure as other ISO management standards, it fits easily alongside ISO 9001 quality management.

One key fact: ISO does not certify companies. Independent certification bodies audit your system and issue the certificate. That point matters when you compare providers or check a certificate.

ISO 22000 versus HACCP

The ISO 22000 vs HACCP question comes up in almost every first meeting with a buyer.

People often ask whether they need ISO 22000 or just HACCP. They are related but different.

HACCP is a method to identify and control food safety hazards at critical points in a process. It has seven principles, from hazard analysis to record keeping. Our guide to HACCP and food safety certification for African food exporters explains these in plain language.
ISO 22000 includes HACCP principles but wraps them in a full management system with prerequisite programmes, management commitment, resource planning, internal audit and continual improvement.

So HACCP is a core part of ISO 22000, but a HACCP plan alone is not the same as an ISO 22000 certificate. Some buyers accept HACCP. Others want a certificate from a recognised scheme.

Who needs ISO 22000 in Nigeria

No single answer fits everyone. You may need or benefit from ISO 22000 if:

You supply large retailers, hotels, airlines, schools or institutional kitchens that list it in their supplier requirements.
You export food or packaging, and your buyers ask for a food safety certificate.
You make ingredients for other manufacturers who must pass audits.
You want to build a stronger system after customer complaints or recalls.
You plan to move later to a retail scheme such as FSSC 22000, which is built on ISO 22000:2018 according to its public descriptions.

ISO 22000 does not replace Nigerian regulatory requirements. Food products sold in Nigeria must still meet the rules of the relevant authority, including NAFDAC registration for regulated products. Read our NAFDAC registration guide to see how that works. In general, ISO 22000 is evidence of a good system, while NAFDAC registration is permission to market a product.

Steps to ISO 22000 certification

Get the standard and train a team. Buy the current standard from ISO or your national standards body. Choose a food safety team leader and train team members on requirements.
Do a gap analysis. Compare what you do now with what the standard requires. List missing procedures, records and equipment.
Set the scope and policy. Decide which products, processes and sites are covered, and write a food safety policy with management commitment.
Build the prerequisite programmes. Cleaning and sanitation, pest control, maintenance, personal hygiene, supplier approval, traceability and recall, water and waste, and allergen control as relevant.
Carry out the hazard analysis. Draw process flow diagrams, identify hazards, decide which are controlled by prerequisite programmes and which need critical control points, and set limits and monitoring.
Document and train. Write procedures and work instructions that match what staff really do. Train everyone, and keep training records.
Run the system. Operate it for long enough to generate records, usually weeks to months, so the auditor can see it working.
Internal audit and management review. Check your own system, fix the findings, and hold a documented management review.
Select a certification body and request a quote.
Stage 1 and Stage 2 audits. Stage 1 reviews documents and readiness. Stage 2 checks that the system is implemented on site. Fix any non-conformities within the deadlines given.
Receive the certificate, then prepare for surveillance audits and recertification.

Choosing a certification body in Nigeria

The list of certification bodies Nigeria food companies can use includes local and international firms.

Certification is only as credible as the body that issues it. When you compare providers, ask these questions:

Is the body accredited for ISO 22000 certification, and by which accreditation body? Accreditation is a separate step in which a recognised accreditation body checks that the certification body is competent.
Does the accreditation cover your food category and scope?
Are its auditors experienced in your sector, such as bakery, beverages, meat or oils?
Will the certificate be accepted by your buyers or export markets? Ask the buyers directly.
Are fees, travel costs and surveillance audit charges written in the quote?

Nigeria has a national accreditation body, NiNAS (Nigeria National Accreditation Service), which accredits certification bodies and laboratories against international standards. The Standards Organisation of Nigeria has also reported that its management systems certification department attained international accreditation from the International Accreditation Service for several standards, including ISO 22000:2018, in an announcement published in March 2024. Foreign certification bodies also operate in Nigeria. Check the current status of any provider you consider, because accreditations change. ISO suggests verifying certificates through the issuing body or the IAF CertSearch database.

ISO 22000 certification cost: what drives the price

Search for "ISO 22000 certification cost" and you will find wide ranges and many promises. We have not verified any price list, so we do not give numbers. These factors usually decide the total:

Size and complexity. Number of employees, shifts, production lines and sites.
Product risk. Ready-to-eat or high-risk foods need deeper analysis than low-risk dry goods.
Your starting point. A site with good hygiene and records needs less work than one starting from scratch.
Consultant support. Optional, but many companies use it for gap analysis and training.
Facility upgrades. Floors, drainage, handwashing stations, pest proofing, laboratory equipment.
Certification body fees. Audit days, travel and annual surveillance.
Internal time. Staff hours spent on documentation, training and audits, which is often the largest hidden cost.

Ask at least two certification bodies for written quotes using the same scope description, so that you compare like with like.

Common reasons companies struggle

Copying another company's manuals without adapting them to the real process.
Weak management commitment, so staff treat it as paperwork.
Poor traceability, where the company cannot link batches of raw material to batches of finished goods.
Records filled in at the end of the week instead of at the time of the task.
Unvalidated critical limits, such as cooking or cooling temperatures with no supporting evidence.
No mock recall exercise.
Neglecting allergen control and cleaning verification.

Certificates are also only part of the picture for exporters. See product certification explained for how food safety certificates fit with product and import documents.

Frequently asked questions

Is ISO 22000 mandatory in Nigeria? The standard itself is voluntary. Buyers or specific regulations may require it or similar assurance, so confirm with your customers and the relevant authorities.

What is the difference between ISO 22000 and HACCP? HACCP is a hazard control method. ISO 22000 is a full management system that includes HACCP principles, prerequisite programmes and management processes.

How long does it take to get ISO 22000 certified? It depends on how prepared you are, the size of the site, and audit scheduling. Allow enough time for the system to operate and produce records before the audit.

Does ISO 22000 certificate expire? Certificates are typically valid for a set cycle with surveillance audits in between. Ask your certification body for the exact cycle.

Is ISO 22000 accepted by every retailer? No. Some buyers require schemes such as FSSC 22000, BRCGS, IFS or SQF. Ask your key customers which scheme they accept before you invest.

Can a small food business get certified? Yes, the standard is designed for organisations of any size, though small companies must still show a working system and evidence.

Getting started

Begin with a gap analysis, a list of customer requirements and two certification quotes. Food businesses that want to reach new buyers can apply as a supplier on Comilmart, and buyers can describe their food safety requirements in a sourcing request. Comilmart connects buyers with verified sellers across Africa, and there are no listing fees to get started. This is general information, so confirm requirements with certification bodies and regulators such as NAFDAC and SON.
