Food safety assurance in the frozen production supply chain is a complex process, involving multiple links and elements. Here are some suggestions and measures to ensure the safety of frozen food:

1. **Application and innovation of technical equipment * *:

-Strengthen basic research on logistics and transportation to lay a theoretical foundation for the development of cold chain logistics.
-Apply environmentally friendly, green and healthy natural industrial substances, and adopt environmentally friendly and energy-saving refrigeration processes.
-Research and develop new cooling equipment and cold chain transportation tools, realize modern graded pre-cooling equipment in mobile form, new fresh-keeping and shock-absorbing packaging materials, green anti-corrosion products and technologies.
2. * * Improve the informatization level of cold chain logistics industry * *:

-Strengthen the mobile Internet, Internet of things, satellite positioning and other advanced modern scientific information technology.
-Equipped with the whole process of temperature automatic monitoring system, control system, recording system and vehicle positioning tracking system.
-Build the cold chain logistics industry related data and information in the collection, collation, analysis and release level of professional system.
3. **Innovation at the management level * *:

-Pay attention to modern advanced cold logistics management technology, take innovative ideas to do a good job in the innovation and development of cold chain logistics industry.
-Encourage professional cold chain logistics enterprises to realize resource sharing and optimize the circulation and organization of cold chain logistics.
-Provide services related to cold chain logistics, and create services such as cold chain joint distribution and food cold chain distribution.
4. * * Basic network measures to improve and optimize cold chain logistics * *:

-Strengthen the basic facilities of the cold chain logistics industry, and gradually cover the cold chain logistics network between the main production areas and consumption areas nationwide.
-Encourage regional and national agricultural wholesale markets to build cold chain logistics equipment in the form of freezing, refrigeration, processing and circulation.
5. **Food safety standards and epidemic prevention and control management * *:

-Follow the "Food Cold Chain Logistics Hygienic Code" and other national food safety standards, and put forward specific requirements for food facilities and equipment, handover, transportation, distribution, and storage in the cold chain logistics process.
-Strengthen the management of epidemic prevention and control, prevent cross-contamination of food, protect operators, and implement the main responsibility of enterprises.

Through the comprehensive implementation of the above measures, the food safety in the frozen production supply chain can be effectively guaranteed.
