Organization of food in a preschool educational institution (DOU) requires strict compliance with sanitary and epidemiological standards, and refrigeration equipment occupies a central place here. Hygienic processing surfaces in contact with food is a critical procedure in preventing the spread of intestinal infections among children. Any deviation from the regulations can cause serious illnesses and problems with the inspection bodies of Rospotrebnadzor.
Many managers and medical personnel are faced with questions about the frequency of processing and the choice of permitted ones disinfectants. The process of cleaning a refrigerator in a kindergarten is fundamentally different from cleaning at home, as it is regulated by strict legislation. In this article, we will analyze a step-by-step algorithm of actions that will protect the health of pupils and ensure that they pass any inspections without fines.
Particular attention must be paid not only to the internal chamber, but also to the outer surface, handles and seals, where pathogenic microflora accumulate. According to current requirements, to treat surfaces in contact with food, it is necessary to use products of the 4th hazard group that do not require rinsing with water. This allows minimize the chemical impact on products, maintaining their safety for baby food.
Regulatory framework and requirements of SanPiN
The main document regulating the activities of preschool institutions are SanPiN 2.3/2.4.3590-20 "Sanitary and epidemiological requirements for the organization of public catering for the population." It is this regulatory act that dictates the rules for maintaining a catering unit, including storage areas and refrigerated cabinets. Failure to comply with the standards prescribed in it entails administrative liability.
According to the requirements, all equipment must be kept clean. It is prohibited to store raw products (meat, fish, eggs) and ready-to-eat dishes together in the same refrigeration unit without sealed packaging. Sanitary treatment must be carried out regularly, and not only when visible dirt or odor appears.
It is important to understand that control over the implementation of these rules rests with the head of the institution and the person responsible for nutrition. Appropriate records must be kept in the catering department's health log to confirm that disinfection measures have been carried out. Lack of records is equivalent to failure to process.
Necessary tools and equipment
For high-quality and safe cleaning, it is necessary to prepare special equipment that should not be used for other household needs. The use of household chemicals from the supermarket is strictly prohibited, since they do not have the necessary certificates of state registration for food production.
The cleaner's arsenal must include special detergents approved for use in children's institutions. They must possess disinfecting effect and not leave toxic traces. You will also need separate sponges or rags, which after use will undergo mandatory disinfection and drying.
- 🧴 Permitted disinfectants (based on chlorine, oxygen or quaternary ammonium compounds).
- 🧽 Separate sponges or rags for internal shelves and external surfaces.
- 🪣 Containers for diluting working solutions with markings.
- 🧤 Rubber gloves to protect the skin of personnel's hands.
When choosing a chemical, pay attention to the hazard class. For internal chambers, products based on active oxygen or specialized sprays for the food industry that evaporate quickly or are safe in small concentrations are best.
Schedule and frequency processing
The frequency of washing refrigeration equipment depends on the type of cleaning: routine or general. Routine cleaning is carried out daily or when soiled, but at least once per shift. It includes removing crumbs, wiping spilled liquids and disinfecting handles.
General cleaning with complete defrosting (if the equipment is not a system No Frost) and thorough cleaning of all surfaces should be carried out at least once a week. In the summer or when the refrigerator is heavily loaded, it is recommended to increase the frequency of procedures.
⚠️ Attention: If mold or a persistent unpleasant odor is detected, treatment should be carried out immediately, regardless of the schedule. In this case, the products must be moved to backup equipment.
All measures taken must be recorded in the sanitary measures log. It indicates the date, time, product used, its concentration and the name of the person responsible. This is the first document that inspectors request during an inspection.

Step-by-step instructions: how to wash properly
The cleaning process must take place in a certain sequence to avoid secondary contamination of already washed areas. First, mechanical cleaning of visible contaminants is carried out, then a cleaning solution is applied, exposure is maintained and washed off (if required).
Particular attention should be paid to hard-to-reach places: corners, shelf joints, rubber seals and ventilation grilles. It is in these areas that bacteria most often form biofilm , which is difficult to remove by ordinary wiping. To clean the seals, it is convenient to use cotton swabs or a soft brush.
After treatment with chemicals that require rinsing, the surfaces are wiped with clean water and wiped dry with disposable towels. You cannot leave the refrigerator damp, since a humid environment promotes the proliferation of microorganisms.
| Stage | Action | Tools |
|---|---|---|
| 1. Preparation | Disconnection from the network, unloading products | Containers for products |
| 2. Mechanical cleaning | Removing crumbs and debris | Dry rags, scraper |
| 3. Processing | Applying disinfectant, exposure | Sprayer, sponge |
| 4. Finish | Wipe with water (if necessary), drying | Clean water, dry wipes |
What to do with rubber seals?
Rubber cuffs on doors are an ideal place for mold to grow. They should not be rubbed with abrasives. Use a soft sponge soaked in a weak solution of vinegar or a special rubber cleaner, thoroughly blotting the folds. After treatment, be sure to wipe the seal dry so that the rubber does not crack.
Disinfection and odor control
Eliminating unpleasant odors in a kindergarten refrigerator is not only an aesthetic task, but also a hygienic one. The smell may indicate spoilage or bacterial growth. The use of flavors and air fresheners in food refrigerators is strictly prohibited.
Sorbents of natural origin are used to combat odors and microbes. Activated carbon, soda or special odor absorbers for refrigerators (fragrance-free) can be placed on the shelves. They are safe for children and effectively adsorb volatile compounds.
If the smell is persistent and cannot be eliminated by standard washing, you need to check the drain hole (if there is one) for blockages. Mucus often accumulates in the drainage tube, which becomes a source of stench. Cleaning is carried out using a brush and a disinfectant solution.
⚠️ Attention: Never use high concentrations of chlorine-containing products or aromatic oils to eliminate odors in a children's refrigerator. Vapors of these substances can get on food and cause allergies or poisoning in a child.
Typical errors and violations
One of the most common mistakes is storing food in open containers. Raw eggs, meat and dairy products must be kept in closed containers or original packaging. This prevents bacteria from settling on the shelves and walls of the refrigerator.
Another mistake is using the same rags to wash the kitchen floor and wipe down refrigerators. Equipment must be strictly marked and used only for its intended purpose. Violation of this rule negates all disinfection efforts.
- ❌ Ignoring the temperature regime (overloading the refrigerator).
- ❌ Using dirty containers to store leftover food.
- ❌ Lack of a temperature and cleaning log.
- ❌ The use of folk remedies (vinegar, lemon) instead of certified chemicals for disinfection.
Violation of the commercial neighborhood is also common. Even short-term storage of raw fish next to ready-made salad can lead to salmonellosis or other infections. Monitoring of this must be constant.
Control and documentation
All activities related to the maintenance of refrigeration equipment in a kindergarten must be documented. The main document is the temperature control and sanitization log. Entries are made into it daily.
The log indicates the date and time of temperature measurement, thermometer readings, and the signature of the person in charge. A separate log of finished product rejection and a sanitary processing log are kept. The presence of these documents confirms compliance with the requirements SanPiN.
When checking Rospotrebnadzor, they first of all pay attention to the compliance of the actual condition of the equipment with the entries in the logs. If there is a washing mark in the logbook, and mold is visible in the corner of the refrigerator, this is regarded as a gross violation.
How often should logbooks be changed?
Accounting logbooks must be laced, numbered and sealed with the seal of the institution. They are stored for the period established by the nomenclature of cases (usually at least 1 year after the last entry), and must be available for inspection at any time.
Is it possible to wash a refrigerator in a kindergarten with soap?
The use of ordinary laundry or toilet soap is not recommended, since it does not have a sufficient disinfectant effect and may leave a film. It is necessary to use specialized detergents approved for children's institutions.
Is it necessary to defrost a No Frost refrigerator?
Refrigerators of the system No Frost do not require regular defrosting to remove ice. However, sanitization (washing with a disinfectant) of the internal chambers must be carried out according to a schedule, even if there is no ice.
How to wipe refrigerator handles?
Door handles are objects that are often touched by hands, so they are the main source of the spread of infection. They must be wiped with a disinfectant solution at least 2-3 times a day, especially after the arrival of food.
What to do if there is mold in the refrigerator?
It is necessary to urgently empty the chamber, remove visible foci of mold mechanically, then thoroughly treat all surfaces with a strong disinfectant (for example, chlorine-based, if the material allows, or oxygen), leaving for the duration of exposure, then rinse thoroughly and dry.
