Prerequisite Programmes Explained: The Foundations Your HACCP Plan Sits On

The part of food safety nobody names but everyone needs

You'll hear a lot about HACCP and critical control points, but underneath them sits something just as important and far less talked about: prerequisite programmes. They're the foundation your entire HACCP plan rests on, and without them in place, no HACCP plan can actually work.

If you've read about cleaning, pest control, personal hygiene, or supplier approval, you've already met prerequisite programmes without necessarily knowing the collective name. Here's what they are, why they matter, and how they fit together.

What a prerequisite programme is

A prerequisite programme (PRP) is a basic condition or activity necessary to maintain a hygienic environment for producing safe food. Where critical control points target specific significant hazards at specific steps, prerequisite programmes manage the general conditions across your whole operation.

Think of it this way: HACCP identifies and controls the specific points where a hazard must be eliminated or reduced. Prerequisite programmes create the safe environment within which that production happens. Cooking a product to a verified temperature is a critical control point. Keeping the kitchen clean, the pests out, and the staff hygienic are prerequisite programmes. You need both, and the CCPs only mean anything when the PRPs are solid beneath them.

Why your HACCP plan depends on them

This relationship is the key insight. A HACCP plan assumes a baseline of good hygiene practice. It assumes your premises are clean, your equipment is maintained, your staff wash their hands, your suppliers are approved, and pests are controlled. If those foundations aren't there, the controls in your HACCP plan are built on sand.

This is also why the modern approach to determining critical control points starts by asking whether a hazard can be controlled by prerequisite programmes. Many hazards are properly managed by good hygiene practice rather than needing a dedicated CCP, which keeps your CCPs focused on the genuinely critical points. Strong prerequisite programmes therefore make your whole HACCP plan simpler and more robust.

The core prerequisite programmes

The exact list varies by business, but the core PRPs that nearly every small food producer needs are:

1. Cleaning and disinfection: a documented cleaning schedule covering what, how often, how, and with what.
2. Pest control: procedures to keep pests out and detect any that get in.
3. Personal hygiene: handwashing, clothing, illness reporting, and related rules.
4. Maintenance: keeping premises and equipment in good, cleanable condition, and handling breakdowns hygienically.
5. Supplier approval and traceability: buying from approved suppliers and being able to trace materials.
6. Waste management: storing and removing waste hygienically.
7. Water safety: where relevant to your process.
8. Temperature control: appropriate refrigeration, freezing, and hot holding.
9. Training: ensuring staff are competent for the work they do.
10. Glass and hard plastic control: policies to prevent physical contamination.

Each of these is a programme in its own right, with its own procedure and its own records. Several have their own detailed guides: cleaning schedules, pest control, personal hygiene, supplier approval, temperature monitoring, and cross-contamination control all sit within this foundation.

Documented procedure plus records

For each prerequisite programme, the pattern is the same and it mirrors HACCP itself: a documented procedure that says what you do, and records that prove you're doing it. A cleaning schedule with no cleaning records, or a pest control contract with no monitoring records, is only half a programme. Auditors and EHOs look for both halves.

This is also where prerequisite programmes most often slip, not because producers don't do the work, but because the records are scattered, develop gaps, or can't be found at audit. Each PRP generates its own paperwork, and across a dozen programmes that's a lot to keep current by hand.

Keeping the foundations visible

The practical challenge with prerequisite programmes is that there are many of them, each generating ongoing records, and they're easy to let drift individually until an audit pulls them all together and the gaps show. Keeping them in one place changes that: when your cleaning records, pest monitoring, training, temperature logs, and supplier certificates all live in a single system, you can see at a glance whether each foundation is being maintained, and produce the evidence on demand.

This is much of what a compliance platform is for. FoodSafe holds your prerequisite programme records, alongside your HACCP plan, supplier register, and allergen information, in one place, with timestamping so records are trusted and an audit pack generator that compiles everything when you need it. The effect is that the foundations stay visible and maintained rather than quietly degrading between audits.

Get the foundations right first

It's tempting to focus on the HACCP plan as the centrepiece of food safety, but the plan is only as good as the prerequisite programmes beneath it. Get your cleaning, pest control, hygiene, maintenance, supplier, and training foundations solid and documented, and your HACCP plan becomes both simpler to build and genuinely effective. Neglect them, and the most elaborate plan in the world won't keep your food safe or pass your audit.
