How Modern Freezing Technologies Affect Food Safety: Challenges and Solutions

1. Current Regulatory Framework and Inspection System

1.1. Main regulatory documents.

Currently, frozen ready-to-eat meals are subject to the following Technical Regulations of the Eurasian Economic Union (TR EAEU):

• TR CU 021/2011 "On Food Safety": Establishes general requirements for all food products (microbiological and chemical indicators, labeling).
• TR CU 027/2012 "On Safety of Certain Types of Specialized Food Products": Regulates products for baby and dietetic food and, importantly, can be applied to products positioned as "healthy food". -
• TR CU 022/2011 "Food Products in Terms of Their Labeling": Defines the requirements for information on the packaging.
• TR CU 029/2012 "Safety Requirements for Food Additives and Flavorings": Critically important for recipe control.

For this product category, a declaration of conformity is mandatory. Certification is voluntary but is often used as a tool to confirm higher quality standards (for example, according to GOST R ISO 22000-2019).

1.2. State control and supervision procedures.

Control is exercised by Rospotrebnadzor. However, since 2022, there has been a moratorium on scheduled inspections for most enterprises, including food manufacturers. Currently, supervisory activities are mainly conducted in the following formats:

• Unscheduled on-site inspections. However, these occur only if there are specific consumer complaints about harm caused, or by order of law enforcement agencies.
• Test purchases, which are conducted without warning; products are purchased and sent for laboratory testing.
• Supervisory activities without interaction with the business, such as analyzing labeling data, information from official websites, and data from partners.

2. Key Problems and Risks from a Food Safety Perspective

2.1. Gaps in regulatory frameworks.

The main problem is the lack of a unified industry standard. The concept of "frozen ready-to-eat food" is not legally defined. This leads to the following consequences:

• Vague requirements: the same product (e.g., frozen potato dumplings) can be interpreted as a "flour-based semi-finished product" or a "ready meal," which entails different requirements for microbiological indicators and shelf life.
• Difficulties in declaration: the manufacturer is forced to independently select regulatory documentation to justify safety, creating legal risks.
• Outdated microbiological standards. Current regulations (SanPiN 1.2.3685-21) often do not take into account the specifics of modern shock freezing technologies (e.g., "Smart Ice" technology) and recipes. Requirements for certain indicators (QMAFAnM, coliforms) for "frozen ready meals" can be excessively strict or, conversely, fail to reflect real risks (e.g., the presence of Listeria monocytogenes in products not subjected to reheating).
• A "gray area" for the HoReCa and delivery sectors. The largest market segment — catering and food delivery services — effectively falls outside the strict requirements of the TR CU, as their products are not individually packaged and labeled. This creates unequal competitive conditions and a serious risk to the consumer, as evidenced by the botulism outbreaks in 2024.

2.2. Practical problems in production.

Many production facilities operate on a "commissary kitchen" principle, where chilled, frozen, and semi-finished products are produced on the same line. Existing standards do not always provide clear guidelines for zoning and risk management in such conditions, which can lead to the risk of cross-contamination.

Critical Control Point (CCP) monitoring. For complex multi-component products (e.g., frozen pureed soup), the classic HACCP approach requires significant refinement. Particular difficulties include:

• Validation of pasteurization/blanching processes: It is necessary to scientifically justify that the selected temperature-time regime is guaranteed to destroy target pathogens.
• Temperature control at all stages of logistics and storage; disruption of the "cold chain" is a key risk that the manufacturer cannot always control after shipment from the warehouse.

3. Proposals for Improvement and Development Paths

3.1. Internal improvements.

Introduce internal microbiological standards that are stricter than those stipulated by SanPiN, with an emphasis on pathogen control (Listeria monocytogenes, Salmonella spp.), especially in products consumed after defrosting.

Implement mandatory incoming inspection of raw materials using an expanded scheme, including the control of veterinary drug residues in raw meat and pesticides in vegetables. Strengthen industrial control programs (ICP), eliminating formalism in their implementation.

Introduce per-shift monitoring of the sanitary condition of equipment (ATP tests, swabs for Listeria spp.) in the finished product packaging area. Implement a continuous temperature monitoring system in freezing tunnels and storage chambers connected to an alert system.

Consider purchasing equipment for accelerated microbiological analyses (PCR, enzyme immunoassay methods) for prompt decision-making regarding finished products.

3.2. Industry and regulatory initiatives.

Actively join the working groups under Roskachestvo and the Ministry of Industry and Trade to create a standard for ready-to-eat food. Share best practices and ICP data, which can become a valuable contribution to legislative initiatives.

Come forward with initiatives to introduce a clear product classification and differentiated requirements that take risks into account (e.g., products ready to eat after defrosting versus products requiring reheating).

Integrate innovative developments into production, such as the "Digital Kitchen" and "Digital Product Dossier".

Simultaneously, propose promoting a risk-oriented approach model through industry associations, so that companies that have implemented and certified food safety management systems (ISO 22000, FSSC 22000, etc.) could receive a relaxed regime for unscheduled inspections or longer declaration periods. This would stimulate the entire market to raise quality standards.

Conclusions

In some cases, the current regulatory and normative framework fails to keep pace with the dynamics of the frozen ready meal market, creating risks for consumers and legal uncertainty for conscientious manufacturers. A proactive stance in this case would be to tighten internal standards and control procedures ahead of legislation, while actively participating in the formation of a new, adequate regulatory ecosystem. This approach will not only minimize risks but also allow for active participation in shaping the market.
