Keeping food safe day-to-day depends on more than a well-designed facility it depends on what happens in that facility every single shift. This guide covers the operational side of food safety: cleaning and sanitation procedures, pest monitoring, waste management, and personal hygiene practices for food handlers. If you’re still planning or renovating your facility layout, see our guide to hygienic facility design and equipment requirements for the structural decisions flooring, drainage, equipment materials that make these daily practices easier to maintain. Together, good design and consistent daily practice are what actually keep food safe, not either one alone.

Establishment: Maintenance and Sanitation

Codex Alimentarius’s General Principles of Food Hygiene set out clear objectives for facility maintenance and sanitation: adequate cleaning, effective pest control, proper waste management, and ongoing verification that these systems actually work. In practice, the verification piece is where we see the most gaps businesses often have cleaning schedules on paper that aren’t actually being followed, which only becomes visible when a swab test or audit catches it.

1. Maintenance and Cleaning

Establishments and equipment should be kept in an appropriate state of repair and condition to:

Facilitate all sanitation procedures.
Function as intended, particularly at critical steps.
Prevent contamination of food, e.g. from metal shards, flaking plaster, debris and chemicals.

Cleaning removes food residues and dirt which may be a source of contamination. The necessary cleaning methods and materials will depend on the nature of the food business. Disinfection may be necessary after cleaning. Cleaning chemicals should be handled and used carefully and in accordance with manufacturer’s instructions and stored, where necessary, separated from food, in clearly identified containers to avoid the risk of contaminating food.

2. Cleaning Procedures and Methods

Cleaning can be carried out by the separate or the combined use of physical methods, such as heat, scrubbing, turbulent flow, vacuum cleaning or other methods that avoid the use of water and chemical methods using detergents, alkalis or acids.

Cleaning procedures will involve, where appropriate:

Removing gross debris from surfaces.
Applying a detergent solution to loosen soil and bacterial film and hold them in solution or suspension.
Rinsing with water which complies with section 4, to remove loosened soil and residues of detergent.
Dry cleaning or other appropriate for removing and collecting.
Residues and debris.
Where necessary, disinfection.

3. Cleaning Programmes

Cleaning and disinfection programs should ensure that all parts of the establishment are appropriately clean, and should include the cleaning of cleaning equipment. Cleaning and disinfection programs should be continually and effectively monitored for their suitability and effectiveness and where necessary, documented.

Where written cleaning programs are used, they should specify:

Areas, items of equipment and utensils to be cleaned.
Responsibility for particular tasks.
Method and frequency of cleaning.
Monitoring arrangements.

Where appropriate, programs should be drawn up in consultation with relevant specialist expert advisors.

4. Pest Control Systems

Pests pose a major threat to the safety and suitability of food. Pest infestations can occur where there are breeding sites and a supply of food. Good hygiene practices should be employed to avoid creating an environment conducive to pests. Good sanitation, inspection of incoming materials and good monitoring can minimize the likelihood of infestation and thereby limit the need for pesticides.

a) Preventing Access

Buildings should be kept in good repair and condition to prevent pest access and to eliminate potential breeding sites. Holes, drains and other places where pests are likely to gain access should be kept sealed. Wire mesh screens, for example on open windows, doors and ventilators, will reduce the problem of pest entry. Animals should, wherever possible, be excluded from the grounds of factories and food processing plants.

b) Harbourage and Infestation

The availability of food and water encourages pest harborage and infestation. Potential food sources should be stored in pest-proof containers and/or stacked above the ground and away from walls. Areas both inside and outside food premises should be kept clean. Where appropriate, refuse should be stored in covered, pest-proof containers

c) Monitoring and Detection

Establishments and surrounding areas should be regularly examined for evidence of infestation.

d) Eradication

Pest infestations should be dealt with immediately and without adversely affecting food safety or suitability. Treatment with chemical, physical or biological agents should be carried out without posing a threat to the safety or suitability of food.

5. Waste Management

Suitable provision must be made for the removal and storage of waste. Waste must not be allowed to accumulate in food handling, food storage, and other working areas and the adjoining environment except so far as unavoidable for the proper functioning of the business.

Waste stores must be kept appropriately clean.

6. Monitoring Effectiveness

Sanitation systems should be monitored for effectiveness, periodically verified by means such as audit pre- operational inspections or, where appropriate, microbiological sampling of environment and food contact surfaces and regularly reviewed and adapted to reflect changed circumstances.

Where PopularCert Sees the Most Compliance Gaps

Across food businesses we work with, the maintenance and sanitation systems on paper are rarely the problem it’s the gap between the written cleaning program and what’s actually happening day-to-day. Cleaning logs that are filled in retroactively before an audit, rather than in real time, are one of the most common findings during gap analysis, and they’re also one of the easiest to fix once identified: a simple digital or physical sign-off system at the point of cleaning closes this gap without adding significant overhead.

Establishment: Personal Hygiene

Objectives:

To ensure that those who come directly or indirectly into contact with food are not likely to contaminate food by:

Maintaining an appropriate degree of personal cleanliness.
Behaving and operating in an appropriate manner.

Rationale:

People who do not maintain an appropriate degree of personal cleanliness, who have certain illnesses or conditions or who behave inappropriately, can contaminate food and transmit illness to consumers.

1. Health Status

People known, or suspected, to be suffering from, or to be a carrier of a disease or illness likely to be transmitted through food, should not be allowed to enter any food handling area if there is a likelihood of their contaminating food. Any person so affected should immediately report illness or symptoms of illness to the management.

Medical examination of a food handler should be carried out clinically or epidemiologically indicated.

2. Illness and Injuries

Conditions which should be reported to management so that any need for medical examination and/or possible exclusion from food handling can be considered, include:

Jaundice
Diarrhea
Vomiting
Fever
Sore throat with fever
Visibly infected skin lesions (boils, cuts, etc.)
Discharges from the ear, eye or nose

3. Personal Cleanliness

Food handlers should maintain a high degree of personal cleanliness and, where appropriate, wear suitable protective clothing, head covering, and footwear. Cuts and wounds, where personnel are permitted to continue working, should be covered by suitable waterproof dressings.

Personnel should always wash their hands when personal cleanliness may affect food safety, for example:

At the start of food handling activities.
Immediately after using the toilet.
Immediately after handling raw food or any contaminated material
Before handling ready-to-eat food, to avoid cross-contamination from raw food contact

4. Personal Behaviour

People engaged in food handling activities should refrain from behavior which could result in contamination of food, for example:

Smoking
Spitting
Chewing or eating
Sneezing or coughing over unprotected food

Personal effects such as jewelry, watches, pins or other items should not be worn or brought into food handling areas if they pose a threat to the safety and suitability of food.

5. Visitors

Visitors to food manufacturing, processing or handling areas should, where appropriate, wear protective clothing and adhere to the other personal hygiene provisions in this section.
