Critical control point examples include cooking, chilling, cooling, hot holding, allergen controls, acidification, and metal detection. These process steps are designed to prevent, eliminate, or reduce food safety hazards to an acceptable level.

Identifying the correct critical control points (CCPs) is one of the most important parts of developing a HACCP plan. The exact CCPs used by a restaurant, care home, or central  kitchen will vary depending on the hazards present and the processes used.

Understanding common critical control point examples makes it easier to identify which controls are necessary to keep food safe and maintain HACCP compliance.

 

What are critical control points and examples?

A critical control point is a process step where a food safety hazard can be prevented, eliminated, or reduced to an acceptable level.

Examples of critical control points include:

  • Cooking chicken to 75°C
  • Chilling high-risk foods below 8°C
  • Holding hot food above 63°C
  • Cooling cooked foods before storage
  • Monitoring product acidity during preservation
  • Verifying allergen labels before dispatch
  • Detecting metal contamination during production

CCPs are identified during hazard analysis and form part of a wider HACCP food safety management system. Each CCP must control a specific biological, chemical, physical, or allergen hazard.

If you're developing a HACCP plan, understanding the relationship between hazards, CCPs, critical limits, monitoring procedures, and corrective actions is essential. Our guides on HACCP, HACCP principles, and how to write a HACCP plan explain this process in greater detail.

 

How to identify a critical control point

Food safety teams identify CCPs by conducting a hazard analysis and evaluating where hazards can be controlled most effectively.

A process step is usually classified as a CCP when:

  • A significant food safety hazard has been identified.
  • The step directly controls that hazard.
  • A measurable critical limit can be established.
  • Failure of the control could result in unsafe food.
  • No later step provides equivalent hazard control.

Activities such as cleaning, pest control, supplier approval, maintenance, and staff training support food safety through prerequisite programmes (PRPs). These controls provide the foundation for HACCP and help prevent hazards before they reach critical stages.

Digital cleaning checklists improve cleaning consistency, reduce missed tasks, and provide a real-time record for audits and compliance.

In some situations, a control that is normally managed as a prerequisite programme may become a CCP. For example, allergen cleaning verification before an allergen-free production run may be the final opportunity to prevent cross-contact.

A CCP decision tree is commonly used to help HACCP teams make these decisions consistently.

 

Common critical control point examples by hazard type

Hazard type Common CCP examples
Biological Cooking, chilling, cooling, freezing, hot holding
Chemical Acidification, preservative control, packaging verification
Physical Metal detection, sieving, filtration, visual inspection
Allergen Ingredient verification, allergen separation, label checks

 

What are the most common critical control points?

The most common critical control points are cooking, chilling, cooling, hot holding, allergen controls, acidification, and metal detection.

These CCPs control the hazards most frequently associated with foodborne illness, contamination incidents, allergen recalls, and customer complaints.

Cooking controls harmful microorganisms. Chilling and cooling control bacterial growth. Hot holding prevents food entering the temperature danger zone. Allergen controls prevent cross-contact and labelling errors. Metal detection removes physical contamination before products reach consumers.

The exact CCPs used in a food business depend on the results of the hazard analysis and the hazards associated with the products being produced.

 

Critical control point examples for biological hazards

Biological hazards include bacteria, viruses, parasites, and moulds that can cause foodborne illness.

Many CCPs are designed specifically to control biological hazards because microorganisms are one of the leading causes of food safety incidents.

Cooking (thermal processing)

Cooking is one of the most common critical control point examples because it reduces or eliminates harmful microorganisms before food is served or distributed.

For many poultry products, a core temperature of at least 75°C is used to achieve pathogen reduction. Equivalent validated time-temperature combinations may also be used.

Common cooking CCPs include:

  • Cooking chicken products
  • Cooking ready-to-eat meat products
  • Pasteurisation processes
  • Cooked meal production
  • Thermal processing of soups and sauces

A digital cooking log helps teams record cooking temperatures accurately and on time, while giving food safety leaders real-time visibility into compliance across all sites.


Cooking is frequently identified as a CCP
because it may be the final opportunity to control pathogens such as Salmonella, Campylobacter, and E. coli.

For example, roasting chicken in a hospital kitchen serves a food safety purpose because the process is intended to reduce microbiological hazards before service.

Monitoring usually involves temperature checks, calibrated probe thermometers, and documented cooking records.

Chilling and cold storage

Cold storage is commonly used as a CCP because temperatures below 8°C slow bacterial growth and help maintain food safety during storage and distribution.

Many food businesses operate refrigeration systems between 0°C and 5°C to provide additional control.

Products commonly controlled through chilled storage include:

  • Raw meat
  • Poultry
  • Dairy products
  • Prepared foods
  • Ready-to-eat meals
  • Healthcare catering products

Temperature monitoring is particularly important for restaurant groups, care homes, hospitals, food-to-go operators, and central kitchens where large volumes of food are stored.

Failure to maintain safe storage temperatures can allow bacterial populations to increase to unsafe levels.

Cooling

Cooling is a CCP when cooked food is prepared in advance and stored for later use.

The objective of cooling is to move food through the temperature danger zone as quickly as possible to minimise bacterial growth.

Examples include:

  • Cooked rice
  • Soups
  • Sauces
  • Batch-cooked meals
  • Cook-chill healthcare catering products

Common cooling methods include:

  • Blast chilling
  • Shallow containers
  • Ice baths
  • Portioning large batches into smaller containers

Monitoring cooling times and temperatures helps verify that products reach safe storage temperatures within established limits.

A digital cooling log helps teams monitor food cooling temperatures consistently, ensuring food passes through the temperature danger zone safely and within required time limits.


Hot holding

Hot holding is commonly identified as a CCP because maintaining food above 63°C prevents bacterial growth during service.

Examples include:

  • Buffet service
  • School catering
  • Care home meal service
  • Hotel breakfast service
  • Hot food counters

Food held below 63°C may enter thetemperature danger zone where bacteria can multiply rapidly.

Monitoring hot holding temperatures helps ensure food remains safe throughout service.

Critical control point examples for chemical hazards

Chemical hazards include cleaning chemicals, food additives, naturally occurring toxins, allergens, and contaminants that may make food unsafe.

Product formulation and acidification

Acidification is a common CCP because acidity can prevent the growth of harmful microorganisms.

Examples include:

  • Pickled vegetables
  • Preserved foods
  • Fermented products
  • Acidified sauces

Ingredients such as vinegar, citric acid, and lactic acid help create conditions that limit microbial growth.

Monitoring pH levels ensures products remain within validated safety limits.

Additive control

Additives are often used to maintain product safety and shelf life.

Examples include:

  • Preservative dosing
  • Nitrite control in cured products
  • Sulphite management
  • Antimicrobial ingredient verification

Monitoring confirms additives remain within approved limits and continue to provide the intended safety function.

Packaging verification

Packaging materials can introduce chemical hazards if they are unsuitable for food contact.

Examples include:

  • Food-grade packaging verification
  • Container compatibility checks
  • Packaging integrity inspections
  • Supplier compliance verification

This is particularly important for acidic products and extended shelf-life foods.

Critical control point examples for physical hazards

Physical hazards include foreign materials that may injure consumers or contaminate products.

Metal detection and inspection

Metal detection is one of the most common CCPs used to control physical contamination.

Examples include:

  • Metal detectors
  • X-ray systems
  • Sieves
  • Filters
  • Visual inspection procedures

These controls help identify:

  • Metal fragments
  • Glass
  • Hard plastic
  • Stones
  • Packaging debris

Many food manufacturers use automated detection systems because they provide consistent monitoring and verification.

Storage and transport controls

Storage and transport controls can also function as CCPs when they protect products from contamination before distribution.

Examples include:

  • Packaging inspections
  • Vehicle condition checks
  • Seal verification
  • Product protection during transport

These controls help maintain food integrity throughout the supply chain.

A digital receiving log helps teams verify and record deliveries consistently, ensuring food is received at safe temperatures and from approved suppliers.


Critical control point examples for allergen management

Allergen controls are among the most important CCPs in many food businesses because even small amounts of an allergen can trigger serious reactions.

Ingredient verification

Ingredient verification confirms that allergen declarations match approved specifications.

Examples include:

  • Supplier specification reviews
  • Ingredient approval checks
  • Receiving inspections

Allergen separation

Allergen separation prevents cross-contact during storage and production.

Examples include:

  • Dedicated storage areas
  • Colour-coded containers
  • Physical segregation of ingredients

Equipment verification

Cleaning verification confirms equipment is suitable for allergen-free production.

Examples include:

  • Cleaning validation
  • Equipment inspections
  • Production line verification

FoodDocs gives you an overview of the allergens by automatically generating an allergy matrix and keeps it regularly updated with any changes you make to ensure food safety in your kitchen.



Label verification

Label checks confirm that allergen information is accurate before products reach consumers.

Examples include:

  • Packaging approval
  • Final label verification
  • Product release checks

For many businesses, label verification represents the final opportunity to prevent an allergen incident.

What is a CCP decision tree?

A CCP decision tree is a HACCP tool used to determine whether a process step should be classified as a critical control point.

The decision tree guides food safety teams through a series of questions that evaluate:

  • Whether a hazard exists
  • Whether control measures are available
  • Whether the step controls the hazard
  • Whether another step provides equivalent control

Using a decision tree helps ensure CCP decisions are consistent, evidence-based, and aligned with HACCP principles.

For example, marinating chicken may reduce surface contamination, but roasting the chicken provides the validated pathogen reduction step. In this scenario, roasting would typically be identified as the CCP.

What happens when a critical control point is not met?

Failure to meet a critical limit means the process is no longer under control and food safety may be compromised.

Examples include:

  • Food failing to reach the required cooking temperature
  • Refrigeration temperatures exceeding limits
  • Incorrect allergen labels
  • Failed metal detector checks

When a CCP deviation occurs, food safety teams should:

  1. Stop the affected process.
  2. Assess the safety of the product.
  3. Apply corrective actions.
  4. Record the deviation.
  5. Verify that control has been restored.
  6. Review whether improvements are required.

Corrective action procedures should be documented within the HACCP plan and supported by monitoring and verification records.

Digital corrective action tools guide staff through the required steps, reducing delays and ensuring issues are resolved correctly. If a task is out of range, a prompt will guide your team on how to respond, ensuring food safety and saving time on training.
