    Original title: People in the cold chain link and prevent the formation of a "safe chain" for epidemic prevention and control

    From November 13th to 16th, Shandong, Shaanxi, Henan, Hubei, Fujian, Gansu and other provinces have successively reported that cold chain foods have been tested positive for the new coronavirus nucleic acid.
    The cold chain foods involved include frozen fish, frozen shrimp, frozen beef, and frozen pork.
    The main importing countries are Ecuador, Brazil, Indonesia, the Netherlands, Argentina, Russia and other countries

    .

    "More and more evidence shows that frozen seafood or meat products may introduce viruses from countries affected by the new crown pneumonia into our country
    .
    " Wu Zunyou, chief epidemiologist at the Chinese Center for Disease Control and Prevention once said

    .

    How to strengthen the epidemic prevention of imported cold-chain food loading, unloading and transportation? How should employees improve safety protection?

    A few days ago, the Ministry of Transport issued the "Guidelines for the Prevention, Control and Disinfection of New Coronavirus in Road and Waterway Imported Cold Chain Food Logistics" (hereinafter referred to as the "Guide") to protect employees, disinfect transportation vehicles, register cargo information, and deal with emergencies.
    A specific technical guide has been made, and at the same time, it is clearly stipulated that cold chain logistics companies must strictly follow the requirements of the "Guide", and guard against the characters, and do a good job in the prevention, control and disinfection of the new crown virus

    .

    Experts in the industry believe that in the face of normalization of epidemic prevention and control, the characters and prevention measures given in the "Guide" have cast the cold chain into a "safety chain
    .
    "

    There are requirements for work wear, transportation personnel must be "fully armed"

    On November 24, at the 155th new crown pneumonia epidemic prevention and control conference held in Tianjin, Zhang Ying, deputy director of the Tianjin CDC, gave a detailed interpretation of the spread chain of the "Hailian Cold Storage" epidemic
    .
    Previously, according to Tianjin’s official report, on November 8, a loading and unloading worker of Tianjin Hailian Frozen Food Co.
    , Ltd.
    was diagnosed with the 138th local case in Tianjin.
    On November 9, Zhang, a truck driver who had gone to Hailian Refrigerator to pull goods A person was diagnosed as the 139th local confirmed case of new coronary pneumonia in Tianjin

    .
    Zhang Ying explained that the two had been exposed to imported North American pig heads at the same time, and the North American pig head was the source of infection for this epidemic

    .

    In this regard, Lu Hongzhou, secretary of the Party Committee of the Shanghai Public Health Clinical Center and member of the National Health Commission's Disease Prevention and Control Expert Committee, believes that there will be no infection without exposure to live viruses
    .
    At present, the global new crown pneumonia epidemic is still spreading.
    For imported cold chain foods, the new crown virus can survive in a frozen environment.
    This risk is difficult to avoid

    .

    China is already the world's largest meat producer, consumer and importer
    .
    "From January to September this year, China's imports of pork from Europe increased by 107.
    3% year-on-year.
    It is expected that the total imports of meat and edible offal this year will exceed 9.
    5 million tons

    .
    " said Wang Bin, deputy director of the Department of Market Operations and Consumption Promotion of the Ministry of Commerce.

    .

    The huge market demand has promoted the development of cold chain transportation
    .
    Statistics show that from 2014 to 2018, the total demand for cold chain logistics in China increased from 91.
    9 million tons to 188.
    7 million tons, with an average annual growth rate of 19.
    7%

    .
    In 2019, the scale of China's cold chain logistics market was approximately 339.
    1 billion yuan, a year-on-year increase of 17.
    5%

    .

    Such large-scale cold chain transportation has brought serious challenges to the current prevention and control of the new crown pneumonia epidemic
    .

    To strengthen the prevention and control of cold-chain food, the focus should be on controlling people who come into contact with cold-chain food
    .
    "The key is that food packaging contamination is transmitted by humans.
    Human speech and breathing may cause the virus to float in the air, so controlling humans is the essence

    .
    " Jiangnan University Professor and Director of the Institute of Food Safety and Quality Control Yao Weirong explained, Food After the outer packaging is wrapped, all the people who come into contact with it may be the source of pollution

    .

    What do loading and unloading personnel need to do to meet the epidemic prevention requirements? The “Guide” provides clear guidance in the “Prevention and Control Requirements for Loading, Unloading and Transportation”, that is, “In addition to the general personal hygiene requirements, you should wear work clothes and hats, disposable medical masks or disposable medical surgical Masks, gloves, etc.
    , wear goggles and face screens when necessary to avoid frequent contact with the surface of the cargo

    .
    "

    For foods such as meat, seafood, etc.
    imported by international cold chain shipping, especially for the loading and unloading of imported cold chain foods from areas where the epidemic occurred, the "Guide" requires that "port handlers and other operators must wear masks throughout the process of moving goods.
    , To prevent the goods from sticking to the face, touching the mouth and nose with hands, to prevent contact with frozen aquatic products that may be contaminated by the new crown virus, etc.
    During the

    loading and unloading operations, take corresponding signs, warning lines and other isolation measures, and in principle, prohibit crews from entering the dock.
    Area"

    .

    "Code on" traceability to ensure the safety of cold chain food

    Qin Yuming, secretary-general of the Cold Chain Logistics Professional Committee of China Federation of Logistics and Purchasing, believes that in order to improve the control efficiency of cold chain transportation links, it is necessary to clarify the cold chain logistics information reporting and exchange mechanism, and improve the cold chain information collection and management of government supervision departments.
    Processing capacity, enhance industry supervision and quality assurance level

    .

    The "Guide" timely released specific measures for cold chain information collection
    .
    It is clearly stated in the "Cargo Information Registration" that "the owner or forwarder shall actively provide the carrier with relevant customs clearance documents for imported cold chain food, and the cold chain logistics enterprise shall truthfully register the information of the shipment, the information of the vehicle and the ship, the information of the crew (crew), Loading and unloading information and consignee information, etc.
    , are not allowed to carry imported cold chain food that cannot provide the source of purchase.
    Relevant units should actively cooperate with health, transportation, customs, market supervision and other departments to collect relevant samples of imported cold chain food according to their duties And nucleic acid testing of cold chain cargo transportation vehicles"

    .

    The "Guide" also provides technical guidance for port companies, freight yards and other operating units, that is, "Port companies, freight yards and other operating units must truthfully register information on cold-chain food road and water transport vehicles and drivers entering and leaving the port yard.
    Information

    .
    Importers or cargo owners who entrust a third-party logistics company to provide transportation, warehousing and other services, when the goods are delivered to the third-party logistics company, they should take the initiative to provide relevant food safety and epidemic prevention inspection information to the third-party logistics company"

    .

    Many ports have begun to implement "on-code" traceability methods
    .

    On November 17, Tianjin Dongjiang Market Supervision Bureau stepped up its efforts to continuously investigate imported cold chain food companies within its jurisdiction, requiring companies to enter all relevant cold chain food information in a timely manner into the "Tianjin Imported Cold Chain Food Operator Traceability Platform".
    Continuously improve the cold chain traceability information, truly achieve “on-code” traceability, and make every effort to ensure the safety of cold chain food

    .

    According to public information from Tianjin Dongjiang Port District, in the supermarket frozen food area, consumers only need to scan the QR code next to the price tag of frozen food through their mobile phone WeChat to see the product name, barcode, specification, model, and inspection.
    Quarantine certificate, country of origin, import port, importer, sales company, purchase date and other food information

    .
    Through the Tianjin Cold Chain Food Traceability Platform, the entire food process closed-loop control and traceability can be realized

    .

    Strengthen the protection of the logistics process and regularly disinfect the transportation equipment

    The current status of the domestic cold chain logistics market is that on the one hand, there is a potential risk of being contaminated by the new crown virus, and the market demand on the other is explosive growth
    .

    It is understood that the transaction volume of cold chain logistics is increasing at an annual rate of 20%
    .
    Public data shows that compared with 2014, the total cold chain demand in the Chinese market has increased by 153% in 2019; in 2020, the market size of China's cold chain logistics industry will reach 500 billion yuan

    .

    The current situation of the new crown pneumonia epidemic in foreign countries has raised a bigger problem for the international cold chain logistics that is difficult to control in the whole process-how to transport frozen food abroad safely to the country over a long distance?

    In Qin Yuming's view, under the new crown pneumonia epidemic, in order to strengthen the safety protection of the cold chain logistics process, intensive management should be promoted, especially to promote the unitized operation of the whole support to reduce personnel contacts in all links
    .
    For long-distance transportation, in addition to strengthening the protection of the operators, the disinfection of the means of transportation is also crucial

    .

    The “Guide” clearly “strictly disinfect transportation vehicles and resolutely prevent the spread of viruses through transportation channels”, and pointed out that “organize or entrust a qualified disinfection unit to carry out transportation equipment such as imported cold chain food transportation vehicles, ships, and inner walls of refrigerated containers.
    Disinfect regularly"

    .

    The "Guide" also gives specific options for commonly used disinfectants, and lists the effective ingredients and scope of application of various disinfectants
    .
    Alcohol disinfectant, the effective ingredient is 70%-80% ethanol, mainly used for hand and skin disinfection, disinfection of the surface of smaller objects

    .
    Chlorine-containing disinfectant, whose active ingredient is calculated as available chlorine, is suitable for disinfection of surfaces, fruits and vegetables, and food and drink utensils

    .
    Hypochlorous acid disinfectant can also be used to disinfect the air, hands, skin and mucous membranes

    .
    Peroxide disinfectant, the active ingredient of hydrogen peroxide disinfectant is hydrogen peroxide (H2O2), and the mass fraction is 3%-6%

    .
    Peracetic acid disinfectant, its active ingredient is calculated as peracetic acid (C2H4O3), with a mass fraction of 15%-21%.
    It is suitable for disinfection of surfaces and air

    .
    Quaternary ammonium salt disinfectants, whose active ingredients are based on product instructions, are suitable for surface disinfection
