Food safety issues not only involve the vital interests of the masses, but also related to the harmony and stability of the society and the long-term peace and stability of the whole country, the food industry is duty-bound responsibility and obligation to do a good job in food inspection and testing and control the quality of food. Food safety inspection and testing is a key link to ensure food safety. The authority of food safety inspection and testing institutions depends on its scientific and efficient technical management and service system, the establishment of food safety inspection and testing sharing platform, and the application of a series of new generation information technologies such as big data, cloud computing, and the Internet of Things to food safety control. Make full use of and optimize the allocation of these social resources, and integrate advanced management concepts to promote the standardization of food safety laboratory management processes, which can effectively improve the efficiency and quality of testing work, give full play to the technical support and guarantee role of food testing for food safety, and strengthen the ability of the whole society to prevent and control food safety risks.

ABSTRACT: Against the backdrop of accelerating the modernization process of the military, testing and evaluating the adaptability of equipment environment has become particularly important. However, the current equipment testing and appraisal work cannot meet the needs of equipment testing and evaluation under the new system, and it is urgent to systematically sort and analyze it. China has established a relatively complete experimental system, and has made significant progress in both hardware equipment construction and training of experimental personnel. In the evaluation test of single system weapons and equipment, its management and technology are also relatively mature and complete. However, there are new challenges in equipment testing. Therefore, this article proposes an overall approach for equipment environmental adaptability testing and verification under a new system of digital transformation in equipment testing and identification. It grasps the key links in the entire process of testing and identification, spans various stages, and combines virtual and real to comprehensively evaluate equipment.

ABSTRACT: The main purpose of building a carbon neutral laboratory is to develop low-carbon technologies and solutions, aiming to reduce energy consumption and carbon emissions to solve environmental problems. Through advanced technology and practical exploration, establish and improve a low-carbon economic system, expand the scale of related industries, and promote economic structure optimization. The construction plan of the testing laboratory studied in this article has negative emissions after measures such as independent emission reduction, renewable energy, and carbon sequestration during the operation phase, which can be defined as a carbon neutral laboratory. The construction of zero carbon laboratories is one of the important actions for global environmental protection and energy conservation and emission reduction, and is also regarded as the actual implementer of the ecological civilization concept advocating sustainable development. From this, we can gain a deeper understanding and promote the development direction of humanity towards a sustainable and low-carbon future.

Objective To investigate the pesticide residue of fruits and vegetables in Qingpu District of Shanghai, Valuate the risk assessment of pesticide residues in primary and middle school students in Qingpu district. Methods From 2021 to 2022, 252 fruits and vegetables from 7 towns in Qingpu District of Shanghai were collected, and 46 pesticide residues in fruits and vegetables were detected by LC/MS. The acute and chronic dietary exposure risks of primary and secondary school students in Qingpu District of Shanghai was assessed using the results of pesticide residue detection, combined with food consumption in the dietary nutrient intake survey of Qingpu students. Results 15 pesticides of all total 46 pesticides were detected, 12 pesticides exceeded the standard, the highest detection rate was tthiamethoxam (29.76%), the highest exceeding rate was clothianidin (27.78%). Among the 6 kinds of fruits and vegetables, the highest detection rate was strawberry (88.10%), and the highest o exceeding rate was solanaceae (76.19%). The dietary exposure results showed that the acute exposure risks (acute hazardquotient) of methamidophos and dichlorvos weir 562% and 452% respectively, the chronic exposure risk (chronic hazardquotient) of dichlorvos was 434%, and the dietary acute chronic exposure risks of other pesticides were less than 100%. Conclusion There are pesticide residues in fruits and vegetables in Qingpu District of Shanghai. The dietary exposure risk of methamphetamine and dichlorvos in fruits and vegetables is high, which should be paid attention to by the regulatory authorities. The dietary exposure risk of other pesticides is low, but the high detection rate and over-standard rate of fruits and vegetables should be paid attention to.

Objective To analyze the microbiological testing results of hotels, bathing centers, and supermarkets. Methods According to the requirements of the Technical Specification for Public Place Hygiene Monitoring and the Public Place Hygiene Standard Monitoring and Inspection Method, a total of 2372 samples from three types of public places (hotels, bathing centers, supermarkets) were subjected to microbiological testing. Results After analyzing the microbiological testing results of air and public goods from 2021 to 2022, a total of 1124 samples were tested in 2021, of which 1110 were qualified, with a qualification rate of 98.75%; In 2022, a total of 1248 samples were tested, of which 1248 were qualified, with a qualification rate of 100.00%. The microbiological testing results of air and public goods in 2022 were higher than those in 2021 (x2 value=13.586, P<0.05). Conclusion The qualified rate of microbial testing in public places in Jiangyin City in 2022 has increased significantly compared to 2021. However, it is necessary to remain vigilant and strengthen hygiene management to ensure environmental hygiene and personnel health in public places.

Objective To trace the source of a foodborne disease outbreak caused by consuming smoked meat pancakes contaminated with Salmonella enteritidis. Methods Epidemiological investigations were carried out on 8 patients, samples of relevant environment, food and feces were collected, laboratory tests were carried out according to national standards. After bacteria enhancement, suspicious colonies were selected for biochemical identification, and the six strains of Salmonella detected underwent serum agglutination with standard diagnostic sera, drug sensitivity test and pulsed field gel electrophoresis. Result There were 8 cases of this incident, and out of the 6 samples, 6 strains of Salmonella enteritidis were isolated. The detection rates of Salmonella in the food, environmental samples, and cases feces were all 100%. The drug sensitivity test results showed that all strains were resistant to 6 drugs, and the drug resistance spectrum was CT-CTX - TET - CIP - AMP - AMS. They were sensitive to CHL, SXT, ETP, MEM, CAZ, CZA, TIG, AZM, and AMI. The PFGE bands of the 6 strains were consistent, with the homology of ${100}\%$ , and that showed the same clone. Conclusions This incident is a foodborne disease outbreak caused by consuming smoked meat pancakes contaminated with Salmonella enteritidis.
