Food hygiene rules for food manufacturers: what you need to know

Food hygiene regulations are some of the most strictly enforced standards in UK industry.

For food manufacturers, compliance is not just good practice. It is a legal requirement.

Failing to meet hygiene standards can result in enforcement action, lost contracts and serious reputational damage.

With audits becoming more rigorous and retailer expectations increasing, manufacturers must understand exactly what is required.

This guide explains the key legal frameworks, certification standards and practical hygiene controls your business needs to meet. It also outlines the tools and consumables that support ongoing compliance.

What are the mandatory food hygiene rules for manufacturers?

LEGAL REQUIREMENTS IN THE UK

Food manufacturers must comply with two primary pieces of legislation:

• The Food Safety Act 1990
• Regulation (EC) No 852/2004 on the hygiene of foodstuffs, retained in UK law

Together, these form the foundation of food hygiene compliance in the UK.

FOOD SAFETY ACT 1990

The Food Safety Act 1990 establishes the core legal responsibilities of food businesses.

It makes it illegal to:

• Sell food that is harmful to health
• Mislead consumers through labelling or advertising
• Sell food that is not of the nature, substance or quality expected

In simple terms, food must be safe, accurately described and fit for consumption.

REGULATION (EC) NO 852/2004

This is a European food safety standard also used in the UK. 

This regulation sets out the hygiene requirements that food businesses must follow in their operations.

It covers:

• Staff hygiene practices
• Safe food handling procedures
• Implementation of HACCP principles
• Premises hygiene and maintenance

Businesses must put appropriate food safety procedures in place and maintain them.

HACCP REQUIREMENTS

Hazard Analysis and Critical Control Point (HACCP), is a legal requirement for food manufacturers.

HACCP is a structured approach to identifying, assessing and controlling food safety hazards.

It involves:

• Keeping records
• Setting monitoring procedures
• Establishing corrective actions
• Reviewing the system regularly
• Determining critical control points
• Identifying potential biological, chemical and physical hazards

There is no universal HACCP template. Your system must reflect your products, processes and site-specific risks.

During an audit, inspectors will expect to see a documented HACCP plan supported by evidence of monitoring and corrective actions.

BRCGS food safety standard requirements

BRCGS is an internationally recognised food safety certification. While not legislation, it is often required by retailers and supply chains.

It provides a structured framework for managing food safety, quality and operational controls.

HYGIENE ZONES & SEGREGATION

BRCGS outlines best practices for zoning food preparation areas according to different hygiene needs.

There are four main hygiene zones:

1. LOW-RISK ZONE

For packaged or low-risk products with minimal contamination exposure.

2. HIGH-RISK ZONE

For ready-to-eat products that have been fully cooked. These areas require strict segregation, controlled access and filtered airflow.

3. HIGH-CARE ZONE

Designed to reduce contamination from pathogens. Products are typically chilled or frozen.

4. AMBIENT HIGH-CARE ZONE

Similar controls to high-care, but for products stored at ambient temperature.

Clear physical segregation, dedicated equipment and restricted movement between zones are essential.

APPROVED MATERIALS AND EQUIPMENT

Only food-safe, approved materials should be used in:

• Storage
• Handling
• Cleaning
• Food preparation

Tools must be durable, non-shedding and easy to sanitise.

Auditors will assess whether equipment is suitable for its intended use and maintained in good condition.

CLEANING FREQUENCY AND VERIFICATION

Cleaning schedules must be defined, documented and verified.

This usually includes:

• Signed records
• Scheduled deep cleans
• Supervisory verification
• Cleaning after each production run

Without documented evidence, compliance cannot be demonstrated.

Trend analysis and review of cleaning records are also part of strong audit performance.

Required hygiene tools & consumables

Maintaining compliance depends on having the right products in place and available when needed.

COLOUR-CODED EQUIPMENT

Colour-coding helps prevent cross-contamination by assigning tools to specific:

• Areas
• Processes
• Food types

This applies to both food preparation and cleaning equipment.

Common colour-coded items include:

• Cloths
• Knives
• Shovels
• Brushes
• Squeegees
• Chopping boards

Consistency across departments and sites supports clearer procedures and easier auditing.

PPE FOR HYGIENE COMPLIANCE

Personal protective equipment protects both product integrity and staff safety.

In food manufacturing, this typically includes:

• Aprons
• Coveralls
• Overshoes
• Beard covers
• Disposable gloves
• Hair nets or mob caps

Disposable PPE is widely used in higher-risk environments to reduce contamination risks.

Reliable stock levels are essential to prevent operational disruption.

CLEANING CHEMICALS & SANITISATION PRODUCTS

Food-safe cleaning chemicals must be suitable for the specific contamination risks present.

Common products include:

• Descalers
• Detergents
• Degreasers
• Disinfectants
• Washing-up liquid

Correct dilution, safe storage, and COSHH compliance must also be managed and documented.

AUDIT CHECKLIST: WHAT INSPECTORS LOOK FOR

Food inspections can take place without notice. Ongoing readiness is critical.

Auditors commonly assess the following:

1. TOOLS IN GOOD CONDITION

Cleaning and food preparation tools must be fit for purpose.

Inspectors will look for:

• Worn PPE
• Cracked handles
• Loose or shedding bristles
• Damaged chopping boards
• Surfaces that cannot be properly sanitised

Damaged equipment should be replaced immediately.

2. CONSISTENT COLOUR-CODING

Colour systems must be applied consistently across food and cleaning tools.

Inconsistencies increase cross-contamination risk and indicate weak procedural control.

3. DOCUMENTED CLEANING SCHEDULES

Auditors expect to see:

• Cleaning plans
• Verification checks
• Completion records
• Evidence of corrective action

If cleaning is not documented, it cannot be verified.

4. CONTROLLED STORAGE OF TOOLS

Hygiene equipment should be stored in a controlled, low-risk environment.

Best practice includes:

• Clear labelling
• Separation by zone
• Keeping tools off the floor
• Wall-mounted storage systems

Poor storage can compromise otherwise compliant procedures.
