　　Starting from June 13th, Wuhan City will carry out environmental monitoring of supermarkets and farmer’s markets in an all-round way, especially for the daily inspection of frozen chilled food. How is the inspection performed?

How to achieve full coverage?

On October 10, a reporter from the Yangtze River Daily followed the staff of the Jiang'an District Center for Disease Control and Prevention to a farmer’s market on Chen Huaimin Road for sampling.

　　■ Samples inside and outside the refrigerator, leaving no loopholes

　　Lv Yanhua, head of the Comprehensive Health Section of the Jiang'an Center for Disease Control and Prevention, introduced that starting from June 13, the center began sampling and testing environmental samples from supermarkets and farmer’s markets within its jurisdiction. “Every part that may be exposed to meat and seafood products is It is included in the sampling scope, including the operating environment and the weighing platform." The staff adopts a weekly mobile rotation of sampling points to formulate a sampling plan to achieve a full coverage of mobile sampling within the jurisdiction.

　　The reporter learned that the test samples are mainly divided into two categories: environmental monitoring samples and key types of food monitoring. Environmental monitoring includes multi-point smear samples such as supermarket market environment, chopping boards, utensils, storage refrigerators or cold storage internal surfaces, and sewage; The types of food monitoring mainly include imported aquatic products and frozen meat products from various sources.

　　At the scene, the disease control personnel involved in sampling Guo Peng used sampling swabs to repeatedly smear the knives, scales, meat surfaces, etc., and put the swabs carefully into the virus sampling tube. A total of 30 environmental samples were taken. Disease control officer Yao Guangze collects and records the corresponding sample number in time.

After that, they put the samples in a special box for inspection. The temperature in the box is kept between 0℃-8℃. After the sampling work is completed in the morning, the samples will be sent to a third-party testing agency on Hanhuang Road, Hankou. Testing, to ensure the timeliness of sampling and testing, to ensure that the test results are obtained on the same day, and truly "collect and clear daily and submit in time".

　　■ Frozen chilled fresh food "tracks back to the source" for the first time

　　Lv Yanhua told reporters that in order to truly move forward, prevent problems before they happen, prevent the epidemic from rebounding, and effectively protect the health and safety of the people, according to the sampling lists provided by various industry authorities, the scope of testing is from the initial supermarket to The farmer’s market is expanded to places such as frozen meat, seafood product transportation vehicles and meat joint factories, and nucleic acid tests are performed on employees engaged in the sale, transportation, and processing of fresh animal food.

　　"After any frozen chilled food enters the jurisdiction, relevant information will be reported to the district CDC quickly, and we will complete the sampling as soon as possible." Lu Yanhua said that at present, the coverage of sampling and testing is becoming wider and more and more testing points. More and more, for related frozen and chilled food, the "source traceability" was completed as soon as possible. At present, multiple rounds of sampling have been carried out on key places such as meat factory and cold storage in the jurisdiction, and employees have also been tested.

　　The reporter learned that once a sample is tested as positive, the district-level disease control department will immediately report it to the district health authority and the provincial and municipal CDC, promptly review the sample, and simultaneously activate the emergency mechanism to deal with the incident. Products are sealed and controlled, the source and whereabouts are checked, epidemiological investigations are carried out on the practitioners and necessary management and control are carried out, and the site is thoroughly disinfected.

　　■ Complete the test within 24 hours, the result is "full shade"

　　As of October 9th, the Jiang'an District Center for Disease Control and Prevention had monitored a total of 7,899 samples, and the results were all negative, including 4922 environmental samples, 2158 food samples, and 819 employees, of which 1,840 were cold chain food and outer packaging samples .

　　The reporter learned from the Wuhan Centers for Disease Control and Prevention that since July, the city has begun special monitoring of cold chain food, mainly monitoring frozen seafood, frozen meat and environmental samples in the freezer. At present, all samples have tested negative results .

To ensure the accuracy of the test, the sample must be tested within 24 hours.

As the scope of monitoring expands and the sample size continues to increase, the disease control department uses more testing forces to participate.

The CDCs in each district sent part of their self-sampling books to a third-party testing agency, and multiple parties started work at the same time. The testing work continued to accelerate, ensuring the timeliness and accuracy of sampling and testing.

　　According to the relevant person in charge of the Wuhan Centers for Disease Control and Prevention, in accordance with the changes in the epidemic situation, we will continue to carry out normalized and full coverage sampling and testing of large supermarkets, farmer’s markets and cold chains in the city, aiming to carry out risk assessment and research based on the monitoring results, and accurately guide the epidemic situation In the prevention and control work, various measures are truly implemented to ensure the health and life safety of the people, eliminate the hidden risks of epidemic rebound, consolidate the results of epidemic prevention and control, and help restore normal production and living order. The tight line of defense of a safe city has won the "double victory" of epidemic prevention and control and economic and social development.
