Proper organization of the workspace in the kitchen of a restaurant or cafe is not just a matter of convenience for the chef, but a strict requirement of sanitary standards. Labelling of refrigeration equipment is one of the key elements of the HACCP system (HACCP), aimed at preventing risks to consumer health. Errors in the placement of products can lead to cross-contamination, damage to raw materials and serious fines from supervisory authorities.
In this article we will analyze in detail what rules exist for professional refrigerators in public catering, how to correctly design storage areas and why a regular inscription with a marker is not suitable for inspection Rospotrebnadzor. Identification system should be understandable to any employee, even those working in a hurry or in poor lighting.
Clear separation of storage areas for finished products and raw ingredients is the foundation of food safety. Let's look at what tools and methods are used to create effective navigation inside refrigeration chambers.
Regulatory requirements of SanPiN for food storage
The main document regulating the activities of public catering enterprises in Russia are SanPiN 2.3/2.4.3590-20. This set of rules clearly defines the principles of product proximity and labeling requirements. According to the standards, raw and ready-to-eat products must be stored separately, which eliminates the risk of bacterial contamination.
Storing foreign objects, personal hygiene of employees or chemicals is prohibited inside refrigerated cabinets. Commodity Neighborhood implies that foods that do not require heat treatment should not come into contact with raw meat, fish or unwashed vegetables. Violation of these rules is classified as a gross violation of sanitary legislation.
⚠️ Attention: Since 2021, updated sanitary rules have been in effect. Make sure that your internal instructions comply with the current standards of SanPiN 2.3/2.4.3590-20, and not outdated documents from the Soviet period.
To comply with the requirements, it is necessary to implement a system that excludes the human factor. Color coding and clear inscriptions help staff quickly navigate the space, even if the employee is working in the establishment for the first day. The absence of marking is equivalent to its absence in principle and is the basis for the prescription.
Principles of color coding and zoning
One of the most effective ways to visualize storage rules is the introduction of color coding. This system allows you to instantly identify the purpose of a shelf or container, reducing the likelihood of error to a minimum. In a professional kitchen, colors are often correlated with the type of product being processed.
The standard color distribution scheme is as follows:
- 🔴 Red color — intended exclusively for raw meat and offal. This is a high-risk area that requires strict control.
- 🐟 Blue color —reserved for raw fish and seafood. A separate zone prevents the transmission of specific odors and bacteria.
- 🥬 Green color —used for vegetables, fruits, herbs and groceries that do not require heat treatment.
- 🍗 Yellow color —indicates the zone for raw poultry, which is often the source salmonellosis.
- 🍽️ White color — intended for ready-to-eat products, dairy products and semi-finished products.
The use of colored labels or magnetic tapes on refrigerator shelves creates a visual barrier. If a product in blue packaging appears on a shelf with red markings, it immediately catches your eye. Visual control It becomes possible without having to read the small text on each product.
Technical means for marking shelves
The choice of materials for marking in a catering environment is critically important. Plain paper or tape will quickly become unusable due to high humidity, temperature changes and regular sanitization. For industrial refrigerators specialized solutions are required.
The most common and reliable labeling options:
- 🏷️ Magnetic tapes and plates - allow you to quickly change the purpose of the shelf without using glue. They are resistant to moisture and easy to clean.
- 🖨️ Thermal labels for label printers — provide clear printing of barcodes, dates and names. Require the use of thermal transfer printers for durability.
- ✍️ Markers for food production are special indelible markers that can be used to write directly on shelves or special boards, if the material allows.
When used For label printers, it is important to choose the right ribbon. They are optimally suited for refrigeration chambers wax and resin ribbons, which ensure image resistance to abrasion and condensation. Regular paper labels in the freezer can peel off or wear off in one day.
Structure of the information label
Simply writing “Meat” or “Vegetables” is often not enough, especially in large industries with a large assortment. A competent information label must contain comprehensive data on the contents of the storage area. This helps not only in navigation, but also in monitoring expiration dates.
Recommended composition of information on the labeling of a shelf or container:
- Name of the product group (for example, "Raw meat", "Finished products").
- Range of permissible storage temperatures.
- Responsible for the zone (position or name).
- Date of last sanitization of the shelves.
For automation of processes, QR codesare often used, which lead to digital temperature control logs or warehouse leftovers. Scanning the code on the refrigerator shelf allows the technologist to instantly gain access to the check history of this compartment.
Why indicate the temperature on the shelf?
Indicating the temperature on the shelf label helps personnel quickly notice equipment malfunctions. If there is “+2...+6°C” on the shelf and the thermometer shows +10°C, the employee will immediately understand that they need to sound the alarm without waiting for the products to spoil.
It is important that the font on the labels is large enough and contrasting. Using sans serif fonts (for example, Arial or Helvetica) improves readability in low-light conditions inside the camera. The text should be clear even when the protective layer of the label fogs up.
Rules for placing products by levels
Shelf marking is inextricably linked to the physical arrangement of products. There is a strict placement hierarchy dictated by the laws of physics and microbiology. Heavy products and raw materials that require deep freezing or low temperatures are placed at the bottom, and ready-made light products are placed at the top.
Typical vertical distribution of products in a refrigerator:
| Storage level | Type of products | Risk of contamination | Labelling color |
|---|---|---|---|
| Top shelves | Finished products, dairy products, salads | High (risk of contamination) | ⚪ White |
| Middle shelves | Vegetables, fruits, semi-prepared foods in closed containers | Medium | 🟢 Green |
| Lower shelves | Raw meat, fish, poultry (in sealed containers) | Critical (source of bacteria) | 🔴 Red / 🔵 Blue |
Placing raw meat over prepared salads is strictly prohibited, even if the meat is in packaging. In the event of a leak or damage to the integrity of the packaging, bacteria can get on products that are not subject to further heat treatment. Vertical zoning should be reflected in the refrigerator diagram posted next to the equipment.
Monitoring and maintaining a labeling system
Implementing a labeling system is only the first step. For its effectiveness, constant monitoring is required. Labels may fade, peel off, or become unreadable. Regular audit of the condition of marking materials should be included in the schedule of sanitary days.
The person in charge of production or the shift supervisor is obliged to check:
- 👁️ Readability all inscriptions and compliance of color codes with the contents.
- 🧼 Integrity mounts and magnetic holders after washing.
- 📝 Relevance information (for example, if the shelf assortment has changed).
Use laminated cards or special protective frames for paper labels is significantly extends their service life. It is also recommended to have a spare set of labeling materials in stock so that replacing a damaged element takes seconds.
⚠️ Attention: Chemicals for cleaning floors and surfaces can dissolve the adhesive base of the labels. Use only those detergents recommended by the manufacturer of labeling materials, or protect labels with an additional layer of varnish/adhesive tape.
Staff training is the final, but most important stage. Employees must not only see the signs, but also understand their meaning. Regular briefings and testing of knowledge on the HACCP system will help maintain order in refrigeration equipment at a high level.
☑️ Weekly check of labeling
What to do if there is no way to fix magnets in the refrigerator?
If the surfaces of the refrigerator are made of materials to which magnets do not stick (for example, coated aluminum or plastic), use self-adhesive pockets with adhesive designed for low temperatures. An alternative option is to use hanging signs on hooks, if the design of the shelves allows, or install separate sign posts inside the chamber.
Does it need to mark each individual shelf or is one common one enough?
It is necessary to mark each storage area where doubts may arise. If the entire refrigerator is intended for only one type of product (for example, only vegetables), a general label on the door is sufficient. However, in universal refrigerators, where different groups of products are stored on different shelves, marking of each shelf is required to comply with the principles of product proximity.
How often should color markings be changed?
Color markings (colored tapes, magnets) change with physical wear, fading or loss of adhesive properties. There is no specific standard replacement period, but visually the material should not be dirty or damaged. The paper inserts inside the pockets change when the assortment changes or the sheet itself is damaged.
