How to wash a refrigerator in a kindergarten: SanPiN requirements

The organization of meals in preschool educational institutions (DOE) is under the strictest control of supervisory authorities, and compliance with sanitary and epidemiological rules here is not just a formality, but a prerequisite for the safety of children. Refrigeration equipment plays a critical role in this process, since it is it that ensures the safety of perishable products, preventing the proliferation of pathogenic bacteria. Any violation of the temperature regime or hygiene rules can lead to an outbreak of intestinal infection, so the issue of cleaning is given paramount importance.

Food department employees must clearly know how to wash a refrigerator according to SanPiN in a kindergartento avoid fines and, more importantly, problems with the health of pupils. Regulatory documents strictly regulate not only the frequency of procedures, but also the chemical composition of the products used, as well as the technology of work itself. Errors in choosing a cleaning composition can lead to poisoning or damage to equipment.

In this article we will analyze in detail the current legal requirements, permitted brands of disinfectants and the correct algorithm for sanitizing. You will learn about the intricacies of marking equipment and the features of removing specific contaminants in a catering facility.

Regulatory framework and requirements for the cleanliness of equipment

The main document regulating the sanitary condition of kindergartens is SanPiN 2.3/2.4.3590-20 “Sanitary and epidemiological requirements for the organization of public catering population." This regulation replaced many old rules and combined requirements for different types of institutions. It clearly states that all technological equipment, including refrigerated cabinets and chambers, must be kept clean and in good condition.

The key requirement is daily cleaning production premises and equipment. However, there are additional specifics for refrigerators: they must be processed as they become dirty, but at least once a week. This is due to the fact that inside the chambers favorable conditions are created for the development of mold and listeria, which can survive at low temperatures.

⚠️ Attention: The use of household chemicals that do not have a certificate of state registration and are intended for home use in the catering units of kindergartens is strictly prohibited. All products must have a certificate of conformity for food production.

Control over compliance with these standards is entrusted to the head of the institution and the medical worker. A log of sanitary days must be kept regularly, recording the date, time and name of the person responsible. The absence of records is equivalent to a violation of sanitary standards with all the ensuing consequences.

Permitted detergents and disinfectants

The choice of chemicals for washing the refrigerator in a preschool educational institution is limited to a strict list of substances permitted by Rospotrebnadzor. Unlike at home, where you can use baking soda or vinegar, a professional environment requires products with proven effectiveness against bacteria, viruses and fungi. The most commonly used are chlorine-containing compounds, quaternary ammonium compounds (QAC) and oxygen-containing agents.

The most common and accessible agent remains bleach or its modern analogues, such as “Deseffect” or “Javel”. They have a powerful bactericidal effect, but require careful handling due to their pungent odor and corrosive activity. For daily treatment of surfaces in contact with products, less aggressive compositions based on HOUR are often used.

It is important to strictly adhere to the concentration of the working solution specified in the instructions for the preparation. An overdose of the active substance can lead to damage to the rubber seals of the refrigerator or the appearance of foreign odors in the products. Insufficient concentration, in turn, will not provide the required level of disinfection.

Below is a table of the most commonly used products and their purposes:

Frequency of treatment and sanitary days

The regime for washing refrigeration equipment in kindergarten is divided into current and general. Routine cleaning is carried out daily at the end of the work shift. At this time, nursing or kitchen staff wipe down external surfaces, door handles and shelves to remove visible dirt and splashes. Internal chambers are usually not washed during daily cleaning unless there has been a food spill.

General cleaning, including complete defrosting (for equipment without a No Frost system) and thorough disinfection of all surfaces, is carried out at least once a week. In some institutions, following internal regulations, this procedure is timed to coincide with weekends, when the workload of the catering department is minimal. This allows you to efficiently process hard-to-reach places.

In addition to planned activities, there is the concept of extraordinary processing. It is necessary in case of defrosting of equipment due to breakdown, ingestion of raw meat or other products that carry a risk of salmonellosis. In such situations, disinfection is carried out immediately, using solutions with a high concentration of the active substance.

Washing technology: step-by-step instructions

The process of washing a refrigerator in a kindergarten must follow a strict algorithm to guarantee results. First, the equipment is cleared of products, which are moved to backup chambers or thermal containers in compliance with the temperature regime. After this, mechanical cleaning of food residues is carried out.

Next, a working solution of the disinfectant is prepared in the required concentration. All internal surfaces are treated with a soft rag or sponge that does not leave lint: shelves, walls, vegetable drawers. Particular attention is paid to the corners and sealing rubber bands, where dirt most often accumulates.

After applying the disinfectant, it is necessary to wait a while exposure specified in the instructions (usually 15–30 minutes). Then the surfaces are thoroughly wiped with clean water to remove chemical residues and wiped dry with a clean rag. Turning on the equipment and loading products is carried out only after the chambers have completely dried.

⚠️ Attention: It is strictly forbidden to use abrasive powders and hard metal brushes to wash the internal chambers of the refrigerator, as they scratch the plastic, creating an ideal environment for the growth of bacteria.

Marking of equipment and storage of rags

One of the main principles of preventing cross-contamination in preschool educational institutions is the correct labeling of cleaning equipment. Separate buckets, rags and brushes should be allocated for each refrigerator, as well as for different areas inside it (for example, separately for raw meat and finished products). This requirement of SanPiN is aimed at preventing the transfer of microbes from raw products to ready-to-eat products.

All inventory must have a clear identification color or letter marking. For example, rags for refrigerators with dairy products may be blue, and for raw meat - red. After use, the rags are soaked in a disinfectant solution, then washed, dried and stored in a clean, labeled form in special cabinets or on hooks.

Using the same rag to wipe external handles and internal shelves is unacceptable. Refrigerator handles, which are constantly touched with dirty hands, are the main source of external infection, and they should be treated with a separate tool with a more aggressive disinfectant.

How to properly store rags after disinfection?

After washing and disinfection, the rags must be completely dried. Storing wet rags in closed buckets or cabinets is prohibited, as this leads to the growth of bacteria and mold. Dry rags are stored in open containers or hanging.

Features of caring for refrigerators

Modern kindergartens use equipment of different generations, and the approach to cleaning them may differ. Older models require regular defrosting, during which the walls are washed most thoroughly. New refrigerators with the system No Frost do not require defrosting, but their drainage holes and evaporators need to be periodically checked and cleaned of dust and mucus.

For refrigerators with antibacterial coating of the internal walls, you should use only those disinfectants that do not destroy the protective layer. Aggressive chlorine-containing solutions can reduce the effectiveness of silver ionizers or other air purification technologies inside the chamber.

It is important to know that rubber door seals wear out most quickly from frequent contact with bleach, so for them it is recommended to use specialized products for rubber or less concentrated HOUR solutions. Regular lubrication of seals with food-grade silicone (after thoroughly rinsing off the chemicals) will extend the life of the equipment.

Documentation and control

Any cleaning and disinfection in the kindergarten must be documented. For this purpose, a “Temperature Control and Cleaning Log” is kept, where the dates of general cleaning are recorded. The log indicates the date, time of start and end of work, the product used, its concentration and the name of the performer.

The presence of this log is checked by Rospotrebnadzor during scheduled and unscheduled inspections. Lack of records or irregular maintenance of documents is interpreted as a violation of sanitary legislation. In addition, for each chemical cylinder used there must be a safety data sheet and a certificate, copies of which are kept by the nurse or manager.

Responsibility for control lies not only with the performers, but also with the management team. The nurse is required to check weekly the quality of cleaning, the absence of chemical smell inside the cells and the correct storage of equipment. Only a systematic approach guarantees the safety of children's food.

Can ordinary laundry soap be used to clean a refrigerator?

The use of ordinary laundry soap is allowed only for preliminary mechanical cleaning of grease and dirt before disinfection. However, as an independent disinfectant, it is ineffective against many pathogens, so the stage of treatment with a disinfectant solution is required according to SanPiN.

What to do if, after washing, the smell of bleach remains in the refrigerator?

A residual smell indicates poor rinsing of the disinfectant. It is necessary to re-wipe all surfaces with clean water, and then with a solution of citric acid or soda, which neutralizes chlorine. You can load food only after the odor has completely disappeared.

Do you need to wash the outside of the refrigerator every day?

Yes, external surfaces, especially door handles and control panels, are wiped with a disinfectant solution daily at the end of the shift, as they are a high-risk area for transmitting infection from the hands of staff.

What is the water temperature used to prepare the solution?

For most modern disinfectants, it is recommended to use water at room temperature (18–25°C). Hot water can accelerate the volatilization of active chlorine or destroy the structure of some synthetic detergents, reducing their effectiveness.
