Key Principles and Requirements of IFS
Ask an experienced quality manager what separates a certified site from a struggling one and you will rarely hear about a single clever procedure. Strong sites share a set of principles: leadership owns food safety, hazards drive decisions, controls are monitored where they matter, and problems trigger honest correction. IFS Food turns those principles into auditable requirements, then scores how completely you apply them.
Owned by IFS Management GmbH and benchmarked by GFSI, IFS Food version 8, published in 2023, is the current version. Rather than memorising clause text, learn the principles underneath. Auditors test whether those principles work in your factory on ordinary days, with ordinary staff, under ordinary production pressure.
Leadership and responsibility
Senior management must set policy, provide resources, review performance, and stay accountable for food safety and legality. Delegating quality to a technical team while production targets override it is a classic audit failure. Auditors interview senior leaders, read management review minutes, and check whether agreed actions received money, staff, and deadlines.
Clear responsibility matters at every level. Job descriptions, deputies for key roles, and an up-to-date organisation chart help, but lived clarity matters more. If a line operator, a supervisor, and a manager give three different answers about who can stop a line for a food safety concern, the system is unclear whatever the chart says.
Risk-based thinking built on HACCP
IFS requires a food safety system based on Codex HACCP principles. You assemble a competent team, describe products and intended use, build and confirm flow diagrams, analyse hazards, determine critical control points, set validated critical limits, monitor them, and define corrections in advance.
Risk thinking extends beyond HACCP. Allergen risk, fraud vulnerability, defence threats, supplier risk, and cleaning effectiveness all call for structured assessment. A generic copied hazard analysis scores poorly because it misses your raw materials, your process steps, and your site layout. Specificity is evidence of real thinking: name the hazard, explain how it could occur here, and justify the control you chose.
Prerequisite programmes
HACCP only works on top of sound prerequisites: cleaning, pest management, maintenance, personal hygiene, training, water control, and waste handling, among others. Weak prerequisites create so many hazards that no critical control point downstream can compensate.
Process control, traceability, and measurement
Requirements cover the full production process, from purchasing and supplier approval through receipt, storage, processing, packing, and dispatch. Specifications must be current and agreed. Process parameters must be defined, monitored, and recorded. Equipment used for measurement must be calibrated so results can be trusted.
Traceability is a knock-out area in spirit and, for the core requirement, in status. You must link raw materials, work in progress, rework, packaging, and finished product, and you must prove it in a timed test. Quantity checks matter too: a trace that finds paperwork for most but not all material leaves auditors asking where the rest went.
- Approve suppliers on risk and monitor their performance
- Control allergens from receipt through labelling
- Monitor critical control points and act on deviations immediately
- Calibrate scales, thermometers, and detectors on schedule
- Test traceability forward and backward, including mass balance
People, culture, and competence
Training requirements go beyond attendance sheets. Staff need competence for their tasks, hygiene rules need to be understood, and refresher training needs to follow change or failure. Protective clothing, hand washing, illness reporting, and rules for jewellery and personal items are checked by observation on the floor, not only in a handbook.
Food safety culture has become an explicit expectation in recent standard versions. Leaders are expected to promote reporting, learning, and speaking up without blame for genuine concerns. A site where staff hide mistakes will eventually hide a serious one. Auditors sense culture quickly from how people answer questions and how supervisors respond to problems found during the walk-round.
Correction, audit, and improvement
Deviations will happen. What IFS judges is your response: contain affected product, find root cause, correct the cause, check similar areas, and verify the fix held. Internal audits must cover the whole system on a planned cycle and be carried out by competent, independent auditors. Complaints, test results, and non-conforming product data feed management review, which drives improvement rather than simply noting figures.
Knock-out requirements reinforce this loop. Internal audits and corrective action both carry KO weight in IFS Food, so a site that audits itself poorly or leaves corrections unclosed cannot certify, even with a decent percentage score. Around 75 percent or more is needed for Higher level; below that, passing sites sit at Foundation level, a signal to buyers that the system works but has ground to gain.
Documentation deserves mention as a principle in its own right, because it connects all the others. Controlled documents tell staff the current agreed method; records prove the method ran; review of records turns proof into management information. Keep documents short enough to use, owned by named people, and reviewed when processes change rather than on autopilot. Version chaos — old specifications at goods-in, a superseded cleaning method in a folder by the sink — is one of the fastest ways to lose grades across several requirements at once. A simple rule helps: one master list, one current version available at the point of use, and old copies removed the day a new version starts.
Key points
- Leadership accountability, clear responsibility, and real resources sit at the top of the IFS system.
- HACCP based on Codex, supported by prerequisite programmes, drives hazard control; risk thinking also covers allergens, fraud, and defence.
- Process control, calibration, supplier approval, and full traceability connect purchasing to dispatch.
- Competence and food safety culture decide whether procedures survive production pressure.
- Internal audit, root-cause correction, and management review close the loop; KO failures in these areas can block certification.
