Food Hygiene in Collective Catering: HACCP in Practice

Collective catering establishments, including school canteens, company restaurants, hospitals and nursing homes, must control the risks associated with food preparation, storage and distribution. This article presents good hygiene practices, the HACCP method, cold-chain management and food safety inspections, with reference to the Moroccan regulatory framework.

Collective catering requires rigorous food hygiene management. A failure during food preparation, storage or distribution can cause a foodborne disease outbreak, potentially affecting several consumers.

Prevention relies on good hygiene practices, the application of HACCP principles (Hazard Analysis and Critical Control Points), temperature control, traceability and risk-based monitoring. The temperatures and time limits to be applied must be determined according to the food concerned, the process used and the applicable regulations.

1. The Importance of Food Hygiene

Foodborne diseases can be caused by pathogenic bacteria such as Salmonella, Listeria monocytogenes, certain strains of Escherichia coli, Staphylococcus aureus and Clostridium perfringens. They can also result from toxins, viruses, parasites or chemical and physical hazards.

Foods requiring particular attention include raw meat and poultry, minced meat, preparations containing raw eggs, unpasteurised dairy products, fish and shellfish, as well as meals prepared in advance and subsequently cooled before service.

The level of risk depends on the type of food, its initial contamination, preparation and storage conditions, and the people who will consume it. Enhanced precautions are particularly important when meals are served to vulnerable people, including older adults, young children and immunocompromised individuals.

2. Applying the HACCP Method

HACCP is a preventive approach used to identify significant food safety hazards, assess them and establish appropriate control measures.

It is based on seven principles:

1. Conduct a hazard analysis covering biological, chemical and physical hazards.
2. Determine the critical control points (CCPs).
3. Establish critical limits for each identified CCP.
4. Establish monitoring procedures for CCPs.
5. Define corrective actions to be taken when control is lost.
6. Verify that the HACCP system is effective.
7. Maintain the necessary documentation and records.

These principles must be adapted to the establishment, its activities, equipment and identified hazards. Not every operational step is automatically a CCP. Some measures belong to good hygiene practices or prerequisite programmes.

Essential Steps to Control

Cooking: Apply a time-temperature combination capable of controlling the identified microbiological hazards. The required core temperature depends on the food, its preparation and the process used. A single temperature cannot be applied to every food product.

Cooling: Cool food intended for refrigerated storage rapidly, following a validated procedure and applicable requirements. The time and temperature limits must be established for the process used.

Hot holding: Maintain cooked food at a temperature that limits microbial growth, in accordance with the applicable requirements and the establishment’s procedures.

Cold storage: Store refrigerated and frozen foods at temperatures appropriate to their category, packaging and applicable requirements.

Cleaning and disinfection: Implement a plan suited to the premises, equipment and food-contact surfaces. These operations are essential hygiene measures, but they are not automatically CCPs.

Temperatures, time limits, responsibilities and corrective actions must be defined in the establishment’s procedures. Any deviation must be assessed and followed by an appropriate response, with records maintained where necessary.

3. Managing the Cold Chain

Cold-chain management limits microbial growth and helps maintain the safety of perishable foods. It must be controlled during delivery, storage, preparation, transportation where applicable, and service.

Receiving Food Deliveries

On receipt, staff should check:

• The condition and integrity of packaging.
• Whether the products match the order and specifications.
• Product identification and traceability.
• Transportation conditions.
• Temperatures, according to the food category and established acceptance criteria.

Non-compliant products should be assessed and, where necessary, rejected or isolated in accordance with the relevant procedure.

Refrigerated and Frozen Storage

Each food product must be stored at a temperature appropriate to its category and the applicable requirements. Refrigeration equipment must be suitable, maintained and monitored.

The frequency of temperature checks should be determined according to risk. Continuous temperature recording may be used where appropriate.

Raw products should be separated from ready-to-eat foods. Food must be protected from contamination, and stock rotation procedures should be followed.

Food Preparation

Preparation procedures should minimise the time that temperature-sensitive foods are exposed to conditions that encourage microbial growth.

Work should be organised to avoid unnecessary delays outside the required storage conditions and to prevent cross-contamination between raw products, cooked foods and ready-to-eat items.

Cooking

The cooking time and temperature must be controlled. Where necessary, the core temperature should be measured using a suitable, clean and properly maintained instrument.

Cooling Prepared Food

Cooked meals intended for later storage must be cooled using a controlled process that achieves the required storage conditions within the applicable time limit.

A blast chiller may be appropriate, particularly for large quantities. Smaller quantities also require a suitable, validated cooling method.

Food Distribution and Service

Food must be maintained under the prescribed conditions until consumption. It should be protected against contamination and inappropriate handling.

Temperature and display time must be monitored in accordance with established procedures.

Important: Values such as 4°C, −18°C and 63°C are sometimes used as reference points in particular contexts, but they are not universal limits applicable to every food product and every stage of the process. The exact requirements must be verified against the applicable regulations and the establishment’s validated procedures.

4. Organising Food Safety Checks

Food safety monitoring in collective catering includes internal checks and, where applicable, official inspections.

Internal Checks

Internal checks help establish whether procedures are being followed. They may include:

• Temperature records during receipt, storage, preparation and service, according to risk.
• Checks on food condition and packaging.
• Verification of hygiene practices.
• Monitoring of cleaning and disinfection.
• Food traceability and expiry-date management.
• Inspection of equipment and monitoring devices.
• Recording deviations and implementing appropriate corrective actions.

Checks should be proportionate to the risks and adapted to the organisation of the kitchen.

Microbiological Testing

Microbiological testing may be carried out according to identified hazards, the type of food, applicable regulatory requirements and the establishment’s monitoring plan.

Sampling must be appropriate, and results must be interpreted according to the relevant criteria. Surface testing can complement hygiene assessments, but it cannot replace good hygiene practices or process control.

Official Inspections

Official inspections are carried out by the competent authorities, depending on the type of establishment and the applicable legal framework. They may include examining premises, equipment and records, taking samples, and applying administrative measures provided for by law in cases of non-compliance.

Internal checks do not replace official inspections. Conversely, satisfactory results from occasional tests are not, by themselves, sufficient to demonstrate that food safety is consistently under control.

5. Training and Awareness for Food Handlers

Food handlers play an essential role in preventing contamination.

Training and Instructions

Workers should receive training and instructions appropriate to their duties, particularly concerning hygiene rules, cross-contamination, temperature control and the establishment’s procedures.

Training must reflect employees’ responsibilities and the applicable regulatory requirements. A formal HACCP training course in exactly the same format should not be assumed to be legally mandatory in every country or establishment.

Work Clothing

Staff should wear clean clothing appropriate to their activities. Hair coverings and other protective equipment should be used according to the risks and hygiene procedures.

Jewellery and personal items that could contaminate food or compromise hygiene must be controlled.

Hand Hygiene

Hands must be washed at appropriate times, particularly before handling food and after using the toilet, handling waste, handling raw products or performing any activity that could contaminate the hands.

Gloves, when used, do not replace hand hygiene. They must be changed according to the tasks and associated risks.

Health Status

Internal procedures should specify what to do when staff develop symptoms or illnesses that could contaminate food. Any restrictions on food handling and health-monitoring measures must comply with the legal requirements applicable to the establishment.

6. The Regulatory Framework in Morocco

In Morocco, Law No. 28-07 on the safety of food products is a central legal text governing food safety. Decree No. 2-10-473 of 6 September 2011 sets out certain implementing provisions.

The National Office for Food Safety (ONSSA) carries out food safety monitoring and protection activities within its legal remit.

Specific obligations depend on the type of activity, the status of the establishment and the applicable legal provisions. Businesses should therefore verify the requirements relevant to their collective catering activities rather than automatically applying rules from another country.

At international level, the Codex Alimentarius General Principles of Food Hygiene (CXC 1-1969), developed within the framework of the FAO and WHO and revised, among other occasions, in 2022, provide a reference for good hygiene practices and the application of HACCP. The Codex is an international reference and does not replace national legislation.

Conclusion

Food safety in collective catering depends on sound organisation, appropriate hygiene practices, temperature control, traceability and staff training.

The HACCP method helps identify significant hazards and establish control measures suited to each establishment’s activities. It should be supported by relevant internal checks and documented corrective actions.

In Morocco, establishments must verify the regulatory requirements applicable to their activities and consult the relevant official texts. A consistent preventive approach helps reduce the risk of foodborne disease outbreaks and protects consumers.
