ISO 22000

ISO 22000 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand ISO 22000 rather than just read about it. In short: ISO 22000 is a food safety management system by the International Organization for Standardization (ISO) which is outcome focused, providing requirements for any organization in the food industry with objective to help to improve overall performance in food safety. These standards are intended to ensure safety in the global food supply chain.

Key takeaways

ISO 22000 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect ISO 22000 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of ISO 22000 from memory before moving on to harder problems.

Reference excerpt

ISO 22000 is a food safety management system by the International Organization for Standardization (ISO) which is outcome focused, providing requirements for any organization in the food industry with objective to help to improve overall performance in food safety. These standards are intended to ensure safety in the global food supply chain. The standards involve the overall guidelines for food safety management and also focuses on traceability in the feed and food chain.

Food safety Food safety refers to all those hazards, whether chronic or acute, that may make food injurious to the health of the consumer.

ISO 22000 standard ISO 22000 is the most popular voluntary food safety international standard in the food industry with 51,535 total number of sites (as per the ISO Survey 2022). The ISO 22000 family are international voluntary consensus standards which align to Good Standardization Practices (GSP) and the World Trade Organization (WTO) Principles for the Development of International Standards. Defining the requirements for a Food Safety Management System (FSMS) and incorporating the following elements which as defined as FSMS principles:

system management prerequisite programs HACCP principles Critical reviews of the above elements have been conducted by many scientists. Communication along the food chain is essential to ensure that all relevant food safety hazards are identified and adequately controlled at each step within the food chain. This implies communication between organizations both upstream and downstream in the food chain. Communication with customers and suppliers about identified hazards and control measures will assist in clarifying customer and supplier requirements. Recognition of the organization's role and position within the food chain is essential to ensure effective interactive communication throughout the chain in order to deliver safe food products to the consumer.

ISO 22000 and HACCP ISO 22000 has two Plan-Do-Check-Act (PDCA) cycles which operate one inside the other, the first covering the management system, the second the operations (described in ISO 22000:2018, Clause 8), which simultaneously cover the HACCP principles. ISO 22000 references the Codex Alimentarius General Principles of Food Hygiene, CXC 1-1969 which includes HACCP principles and 12 HACCP application steps. The following table explains the relationship and alignment between ISO 22000 and the Codex Alimentarius General Principles of Food Hygiene, CXC 1-1969. The task, Validate the control measure(s) or combination(s) of control measures, also references Guidelines for the Validation of Food Safety Control Measures, CXG 69-2008

A study explains the importance of ISO 22000 Food Safety Management System (FSMS), Critical Control Points Hazard Analysis (HACCP) and the Prerequisite Programs (PRPs) as the foundation of HACCP, in preventing foodborne outbreaks. In addition, another study for HACCP effectiveness between ISO 22000 certified and non-certified dairy companies identified that by implementing the HACCP Food Safety System (FSS) and by being ISO 22000 certified, the level of the achievement of the HACCP objectives is improved significantly.

ISO 22000 family of standards ISO published additional standards that are related to ISO 22000. These standards are known as the ISO 22000 family of standards. At the present time, the following standards will make up the ISO 22000 family of standards:

ISO 22000 – Food safety management systems – Requirements for any organization in the food chain. ISO 22001 – Guidelines on the application of ISO 9001:2000 for the food and drink industry (replaces: ISO 15161:2001 Withdrawn). ISO/TS 22002- Prerequisite programmes on food safety—Part 1: Food manufacturing; Part 2: Catering; Part 3: Farming; Part 4: Food packaging manufacturing; Part 5: Transport and storage; Part 6: Feed and animal food production ISO/TS 22003 – Food safety — Part 1: Requirements for bodies providing audit and certification of food safety management systems; Part 2: Requirements for bodies providing evaluation and certification of products, processes and services, including an audit of the food safety system ISO/TS 22004 – Food safety management systems – Guidance on the application of ISO 22000:2005. ISO 22005 – Traceability in the feed and food chain – General principles and basic requirements for system design and implementation. ISO 22006 – Quality management systems – Guidance on the application of ISO 9002:2000 for crop production. ISO 22000 is also used as a basis for the Food Safety Systems Certification (FSSC) Scheme FSSC 22000. FSSC 22000 is a Global Food Safety Initiative (GFSI) approved scheme, also referred to as a certification programme owner (CPO). The differences between ISO 22000 and schemes with GFSI recognition are explained in a paper from ISO, International standards and private standards.

Worked examples

Example 1 — a first encounter with ISO 22000

Start with the simplest possible case. Write down what ISO 22000 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to ISO 22000 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about ISO 22000 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of ISO 22000

In research: ISO 22000 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses ISO 22000 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: ISO 22000 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Food safety, ISO standards, so understanding it makes those chapters shorter.
In everyday life: Look for ISO 22000 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
