What happened to the newly discovered positive outer packaging of flounder? What about the recent 2 confirmed cases and 1 asymptomatic infected person? The authoritative response came

On the evening of November 11, at the press conference on the prevention and control of the new coronavirus pneumonia epidemic in Tianjin, Gu Qing, deputy director of the Municipal Health Commission and director of the Municipal Center for Disease Control and Prevention, introduced that at 17:12 on November 11, 2020, the Municipal Health Commission received a report from the Municipal Center for Disease Control and Prevention, and it was found in Jinghai District that the "two complete, two coverage" nucleic acid testing of the new coronavirus was carried out on the environment, food and employees of cold chain production and operation enterprises in the jurisdiction. A sample of halibut outer packaging smear sample from Jiequn Aquatic Products Wholesale Store in Taitou Town in the district was positive, and was confirmed as positive after review by the Municipal Center for Disease Control and Prevention.

At present, Jinghai District has carried out traceability and sealing control and management of articles for epidemic-related enterprises, and quickly carried out epidemiological investigation, investigation and disposal. Nucleic acid testing has been carried out on a total of 59 people who have been initially identified as positive specimen exposures, their close contacts, and generally exposed persons, and 23 of the results that have been released are negative, and other results are yet to be revealed.

Preliminary traceability survey results show that this batch of goods came from Jinnan District, jinnan District has tested 45 samples, the results are negative, the relevant testing work is still in progress. The Municipal Health Commission has sent experts from the Municipal Center for Disease Control and Prevention to the relevant areas for on-site guidance and disposal.

Subsequently, Gu Qing introduced the relevant situation of the current treatment of 2 confirmed cases of new crown pneumonia and 1 asymptomatic infected person recently confirmed in our city.

The 138th local confirmed case of new crown pneumonia, Chen Moumou, male, 38 years old, lives in Hangu Street, Binhai New Area, Tianjin, and is a stevedore of Tianjin Hailian Frozen Food Co., Ltd. On November 4, the patient participated in the company's imported frozen food handling work. On November 7, Dezhou City, Shandong Province, reported that the frozen food had found that the outer packaging specimens had tested positive for the nucleic acid of the new crown virus. After receiving the notification, the patient was transferred from the 120 ambulance to the centralized isolation medical observation point in Binhai New Area, and a throat swab was collected for nucleic acid detection of the new crown virus; at about 2 o'clock on the 8th, the new crown virus nucleic acid test was positive, that is, the 120 ambulance was transferred to Haihe Hospital. The municipal clinical expert group confirmed that it was the 138th local case in our city, and the classification was ordinary. Currently, the patient is in stable condition. Close contacts and close contacts have been centrally isolated for medical observation, and the communities and workplaces where they live have been closed and controlled.

For this case, a total of 2549 specimens were screened, including close contacts of the case, close contacts, positive environmental exposure personnel, and residents of the same community. Except for 1 cold storage (doorknob) environmental application of positive nucleic acid in the specimen, the rest of the results were negative. On November 9, the Tianjin Municipal Center for Disease Control and Prevention smeared the respiratory specimens of the disease and related cold storage environments, and the results of the high-throughput sequencing and sequence analysis of the whole genome of the new coronavirus showed that they belonged to the European family branch II of L genotype II (North American branch).

The 139th local confirmed case of new crown pneumonia, Zhang Moumou, male, 47 years old, household registration address is Puyang City, Henan Province, temporary residence is Lingang Road, Binhai New Area, Tianjin City, occupation as a truck driver. It was in the epidemiological investigation of the 138th locally confirmed case carried out in our city, and it was actively discovered after investigation. The patient had driven a truck to the Sino-Singapore Tianjin Eco-City Hailian Cold Storage at about 11:00 a.m. on November 5 to load cold chain goods, and on November 7, our city received a notification from Dezhou City, Shandong Province, saying that after the nucleic acid test of the imported cold chain food issued by our city was positive for the new crown virus, after investigation, on the morning of November 8, the patient tested positive for nucleic acid, and then transferred him from 120 ambulance to Tianjin Haihe Hospital, and was diagnosed as an asymptomatic infected person by the municipal expert group. On November 10, the patient developed fever, dry throat and other symptoms, and was diagnosed as the 139th local confirmed case of new crown pneumonia (mild disease) in the city after being judged by the municipal expert group, and at present, the patient's condition is stable. The patient has no close contacts in Tianjin. For this case, a total of 551 samples of relevant environments and transport vehicles have been collected, and the test results are negative.

After the Municipal Center for Disease Control and Prevention conducted high-genome high-throughput sequencing and sequence comparison of the new coronavirus on the respiratory specimens of this case, the sequencing analysis results on the 11th showed that the European family branch II (North American branch) belonging to the L genotype was consistent with the whole gene sequence sequencing analysis of the virus of the 138th confirmed case.

The third local asymptomatic infected person (including the second asymptomatic infected person has been confirmed as the 139th confirmed case in the city), Wang Moumou, male, 47 years old. The household registration address is Tongliao City, Inner Mongolia, and he currently lives in the Dongjiang Port Free Trade Zone of Binhai New Area, and is a stevedor worker, working in Yangbei Logistics Park, Gangcheng Avenue, Binhai New Area, Tianjin. On the morning of November 10, in the city's cold chain practitioners and frozen goods nucleic acid test "two full coverage" screening, the nucleic acid test was tested, and the result was positive. On the afternoon of the 10th, after the judgment of the municipal expert group, the patient was diagnosed with asymptomatic infection and has now been admitted to Haihe Hospital. At present, the asymptomatic infected person has no relevant clinical symptoms and is in a stable condition. Up to now, 4886 nucleic acid tests have been performed on close contacts, close contacts and other relevant environmental samples, and the results are negative. Close contacts and close contacts have been centrally isolated for medical observation, and the communities and workplaces where they live have been closed and controlled.

Gu Qing said that at present, it is a critical period of epidemic prevention and control in autumn and winter, and some parts of the country, including our city, have successively experienced epidemics related to cold chain food. All districts, departments and units should further strengthen the control of cold chain food production, operation, storage and transportation units and places, strictly implement the relevant requirements of the state on the preventive and comprehensive disinfection of imported cold chain food, further strictly implement control measures for cold chain food employees, places, goods, etc., and strengthen nucleic acid sampling and testing for relevant personnel, places and relevant links. At the same time, we will further tighten the management of each fever clinic, optimize the disposal process, strengthen the prevention and control of hospital infection, and effectively play the role of sentinel. Once a positive nucleic acid test and related risks are found, it is necessary to immediately report and deal with them in a timely manner, strengthen centralized isolation and closed-loop management, and strictly control the spread of the virus.

At the same time, Gu Qing put forward healthy suggestions to the general public on the safe consumption of cold chain food.

First, in the purchase of cold chain food: to go to a regular supermarket or market to buy cold chain food, in addition to the conventional attention to food production date, shelf life, storage conditions and other food label information, should pay more attention to the food origin, source, import food quarantine and other related information, do not purchase cold chain food without clear source information. In fact, imported food is basically the same as domestic products in terms of food composition and nutrient composition, and in the special period of the new crown pneumonia epidemic, do not blindly believe in imported food, thereby increasing the potential risk of infection.

At the same time, when purchasing cold chain food, you should wear a mask correctly, avoid touching the surface of the food with your bare hands, and it is recommended to use disposable gloves to select frozen and chilled food. Wash your hands with soap or hand sanitizer after shopping, and do not touch your mouth, nose, eyes, etc. before washing your hands.

Second, in terms of cleaning and processing: keep the kitchen and utensils hygienic and clean, and wash your hands before handling food. The kitchen should be ventilated, it is recommended to clean and wipe the kitchen countertops and other surfaces frequently, and the cooking utensils should be disinfected frequently. To achieve the separation of raw and cooked, the containers, knives and cutting boards used to process frozen frozen food should be placed separately, and should be cleaned and disinfected in time to avoid mixing with utensils for handling direct food and avoid cross-contamination. Wash your hands before touching cooked food after washing or touching frozen chilled food. Frozen chilled food should be stored in the freezer compartment of the refrigerator, do not store it for too long, and store it separately from cooked food.

The third is in terms of cooking and eating: when cooking and eating frozen and chilled food, it should be cooked thoroughly, and the uneaten food should be eaten for the second time, and in principle, when heated, it should be maintained for 10 to 15 minutes after opening the pot. Try to avoid eating seafood raw, half-raw, wine bubbles, vinegar bubbles or salted foods directly after eating. When family members or multiple people eat together, use public chopsticks and spoons to reduce the risk of cross-infection.

Gu Qing stressed that autumn and winter is the season of high incidence of respiratory infectious diseases, the general public in accordance with the relevant requirements of the normalization of the prevention and control of the new crown epidemic to implement personal protective measures, emphasize the scientific wearing of masks, frequent washing of hands, regular ventilation, maintain social distance, do not get together, do not gather, reduce unnecessary gatherings, meals and other activities, once fever, fatigue, dry cough and other symptoms, must immediately wear masks, avoid taking public transportation, and immediately go to the fever clinic for treatment, truthfully inform personal travel history, activity history and contact history, In particular, it is necessary to truthfully inform the doctor whether there is a recent history of cold chain food exposure. Be sure not to bring illness to work and class.
