Epidemiological Investigation of Food Safety Incidents Technical Guidelines 2012 Edition .

Summary. In the event of a food safety incident, the disease prevention and control institutions at or above the county level shall carry out sanitary treatment of the accident site and carry out epidemiological investigation of the factors related to the accident, and the relevant departments shall assist. Disease prevention and control institutions at or above the county level shall submit epidemiological investigations to the food safety supervision and management and health administrative departments at the same level.

Can you add, I don't quite understand it.

In the event of a food safety incident, the laughing system for the prevention and control of disease residues at or above the county level shall carry out sanitary treatment at the scene of the accident, and carry out epidemiological investigation of factors related to the accident, such as regretting hunger, and the relevant departments shall assist. Disease prevention and control institutions at or above the county level shall submit epidemiological investigations to the food safety supervision and management and health administrative departments at the same level.

Main content:

It includes general provisions, investigation preparation, investigation content and procedures, population disease investigation, related factors investigation, laboratory tests, investigation conclusions, investigation reports, 9 main contents of supplementary provisions and 6 annexes.

1. The general provisions part puts forward the basis for formulating the specification, the scope of application, the principles of accident investigation, the working mechanism and requirements, the equipment and technical support. This part clarifies that the working methods of disease prevention and control institutions are carried out under the unified organization of the health administrative department, and requires that the investigation and handling work of other regulatory departments be coordinated. At the same time, it stipulates the conditions, personnel and other technical preparations that should be met for the epidemiological investigation.

2. The preparation part of the investigation proposes that the accident should be verified before the accident investigation is initiated, and it is stipulated that the disease prevention and control agency shall appoint an accident investigator to set up an investigation team, and put forward the number of people, positions and qualification requirements.

3. The investigation content and procedures part clarifies the investigation tasks of the accident and unifies the epidemiological investigation procedures.

4. According to the characteristics and needs of the epidemiological investigation of food poisoning and foodborne diseases, the basic investigation content is specified in three parts: population disease investigation, related factor investigation and laboratory testing. The process of population disease investigation is carried out in four steps: preliminary investigation, case search, case investigation and data analysis, and specific work requirements are specified for each step. On the basis of the above four links, it is also proposed to carry out population disease surveillance under specific circumstances to pay attention to the occurrence of diseases in non-diseased populations with homologous exposure.

5. The investigation conclusion and report part includes the confirmation of the accident investigation conclusion, the accident assessment and the summary report. This section takes into account the procedures and rules for making epidemiological findings in the event that the investigation fails to produce meaningful results, and also sets out requirements such as reporting on the progress necessary during the investigation.

6. The supplementary provisions give the definition of 11 terms, including the definition of the case. At the same time, it stipulates the precautions in epidemiological investigations, such as the release of information to the outside world and the detection of foodborne infectious diseases.

7. In order to facilitate implementation, the specification provides 6 annexes as technical references, including a list of materials and equipment for accident scene investigation and treatment, a preliminary investigation form, a case investigation form template, a list of case information, a guideline for the diagnosis of foodborne diseases, and a record of the work process of accident epidemiological investigation.

In order to guide and standardize the epidemiological investigation of food safety accidents in China, on June 7, 2012, the General Office of the Ministry of Health issued the Technical Guidelines for the Epidemiological Investigation of Food Safety Accidents (2012 Edition) under the supervision of the Ministry of Health 2012 No. 74. The Technical Guidelines are divided into Introduction, Survey Preparation, Work Requirements, Field Epidemiological Investigation, Food Hygiene Investigation, Sampling and Laboratory Testing, Data Analysis and Investigation Conclusions, and Appendix 8.
