Can imported cold-chain food be eaten with confidence? Five questions cold chain food safety

recently, the positive detection rate of nucleic acid in imported cold-chain food has increased significantly. "When it comes to products ranging from marine products to livestock and poultry meat products, imports are contaminated with viruses from cold-chain foods to containers." Mi Feng, a spokesman for the National Health and Wellness Commission, said the spread of the epidemic is characterized by "things to people" and "people to people".
cold chain food has repeatedly become a "mine zone", imported cold chain food can not eat? How to completely disinfect? Faced with the "cold chain" related to the hot concerns, multi-sector experts to answer public questions.On November 7, German imported pig front elbow packaging specimens entering Tianjin and India imported frozen fish packaging samples of new coronavirus nucleic acid tested positive; Since June this year, the source of local outbreaks in many parts of the country point to imported cold-chain food, salmon, Ecuadorian frozen shrimp and other products have been repeatedly detected to carry the new crown virus.
deputy director of the National Food Safety Risk Assessment Center
believes that foreign countries are in the outbreak period of the new crown epidemic, cross-border transport of cold-chain food and packaging is likely to become a carrier carrying the new crown virus.
recently, various departments and places to increase the import of cold chain food and its packaging of new coronavirus nucleic acid testing and sampling, with the frequency, frequency and coverage of the test increased, the probability of finding a positive increased.
" also shows that china's measures to strengthen physical defense is effective. The
said that up to now, the positive rate of national sampling and testing is 0.48 per 10,000, and mainly concentrated in food packaging." import fresh can not eat? "In the face of imported cold chain food test positive frequency, this issue has become the focus of many people's attention.
" has not found infections caused by direct consumption of these cold-chain foods. Zhang Liubo, chief expert in disinfection at the CDC and director of the Environmental Disinfection and Infection Control Center, said the risk of infection is mainly in the handling, operation and other links, and no infection caused by eating food itself.
Zhang Yubo introduced, the import of cold-chain food packaging surface for safe and effective disinfection, can achieve the new crown pneumonia virus inactivation, disinfection and then contact with the surface, infection risk is very low. However, viral nucleic acids may still exist, and if they are disinfected, they are still positive and the public does not have to be overly nervous.added that the cooking process should also be kept clean, using safe water and raw materials, raw and cooked separately, cooked thoroughly, and keep food at a safe temperature.Joint Prevention and Control Mechanism Integrated Group recently issued the "Import cold chain food preventive comprehensive disinfection work programme", requiring the import of cold chain food before the first contact with people in my territory, the implementation of preventive comprehensive disinfection treatment.
basis, the General Administration of Customs has made specific deployment of preventive disinfection of imported cold chain food at ports, including clarifying the work requirements, operating procedures, disinfection technical specifications and supporting regulatory measures for preventive disinfection at ports. Some ports require cold chain food packaging disinfection with 500mg/L chlorine dioxide disinfection liquid or 0.2% to 0.4% peroxyacetic acid or 3% hydrogen peroxide, spraying or wiping disinfection of the six sides of the outer packaging, acting for 30 minutes, rinsed with clean water.
Customs General Administration of Import and Export Food Safety Bureau Director Bi Kexin introduced, since the program issued as of 24 hours, the port link preventive disinfection of imported cold chain food packaging accumulated more than 1.6 million pieces, weight of more than 30,000 tons, disinfection scope includes the pumped imported cold chain food packaging, containers, air transport trays and so on.
, it is more difficult to disinfect imported cold chain food at low temperature than conventional disinfection. Zhang said that the study of relevant technical methods is being stepped up.first disinfection, then hand washing, anti-splash, check the surrounding, high temperature washing, speed treatment.
, the public should first disinfect the surface of the external packaging when they come into contact with imported cold-chain food, and then carry out hand cleaning and disinfection. When handling the outer packaging, avoid pollution to the surrounding environment. At the same time do a good job of cleaning and disinfection of the surrounding environment, contact with food cooking utensils timely cleaning, used residue separate packaging, timely treatment.
" when purchasing fresh ingredients, avoid touching the mouth, eyes and nose with unclean hands. According
, from the epidemiological traceability analysis, the infected population is a high-risk group of people who are repeatedly exposed to the outer packaging of imported cold-chain foods under certain circumstances, such as porters. many people worry that the virus will not be through the import of cold-chain food into the market chain caused by the spread? Chen , market inspector of the Food Operations Department of the State Administration of Market Supervision, said that the regulatory authorities will focus on five measures: first, timely market risk detection;
since October 30, Tianjin cold chain food traceability platform has been fully operational. Consumers can scan the product packaging or container electronic traceability code, to understand the country of origin, upstream enterprises (importers), inspection and quarantine certificates and other information.
"to sum up the experience of the past 11 months, we are confident that we can prevent a re-emergence of the outbreak." Wu Zunyou, chief epidemiologist at the CDC, said that in the face of the future Spring Festival, as long as there are no infected people in the population will not have a major outbreak.
