Shanghai Food and Drug Administration found that @RISK is important for food contamination monitoring and risk analysis and evaluation.
The Shanghai Food and Drug Administration used @RISK software to conduct pollution monitoring and risk analysis and assessment of food safety in Shanghai, and achieved good results, making an important contribution to ensuring food safety for the people of the city.
@RISK contributes to the safety of food for Shanghai residents
The Shanghai Food and Drug Administration is the government agency responsible for the safety, supervision and implementation of the production, circulation and consumption of food, medicine, health food and cosmetics in the city. As the executive agency of the government administrative affairs, the risk analysis and supervision of various hazards in the field of food supply, especially in the food supply field, are the top priority of their work duties. This is related to the safe supply of various foods in the local area. The food safety of the city's more than 20 million people has an important impact and significance.
Since 2007, Shanghai Food and Drug Administration has used the @RISK software in Palisade's risk and decision analysis software to conduct pollution monitoring and risk analysis and assessment of food safety in Shanghai, especially focusing on Shanghai food service and food circulation. Monitoring and assessment of various pollutions in foods. For example, the Shanghai Food and Drug Administration needs to conduct tests and analysis on various toxic and harmful chemical and biological pollutions in food. Whether it is chemical pollution or microbial contamination, exposure assessment is required. These huge and cumbersome data need to be used. Professional software for quantitative scientific analysis and comparison; in addition, Shanghai Food and Drug Administration will also conduct dietary surveys to obtain data on residents' consumption of various foods. These data also need to be analyzed using professional analysis software, @RISK It is such a powerful professional scientific analysis software. Since the official use of @RISK in 2007, it has played an indispensable role in the effective implementation of scientific food safety supervision and safety protection for the Shanghai Food and Drug Administration.
Prior to the use of @RISK, in the food safety risk analysis monitoring and evaluation work, the main problem encountered by the Shanghai Food and Drug Administration was the inability to fit the chemical contaminants in the food. At that time, the Shanghai Food and Drug Administration mainly used the “average value†to calculate the average exposure risk. This method of calculation and analysis has no way to conduct an accurate quantitative exposure assessment for some sensitive people or high-exposure groups, which leads to the inability to accurately describe this risk. The formation mechanism and development trend, so that it is difficult to make effective measures and decisions, and eventually there may be some high-exposure groups or people who are sensitive to certain harmful substances (contaminants), such as Shanghai food and medicine. The Supervisory Office cannot accurately know whether the health of these people will be damaged and how it is harmed after taking certain products, nor can it establish effective regulatory measures. The Shanghai Food and Drug Administration has also carried out other countermeasures for this purpose, but it has not been able to draw an accurate and universal comprehensive identification. In this regard, Shanghai Food and Drug Administration urgently needs an effective risk analysis and evaluation software to carry out accurate and universal probabilistic assessment, and form a complete set of post-models to obtain accurate exposure assessment results to make scientific Strategic analysis.
@RISK took the lead in adoption and application in Shanghai Food and Drug Administration
Monte Carlo sampling techniques and probabilistic assessments applied to food safety risk assessment began in the 1990s, and around 2005, the use of Monte Carlo sampling technology in China was only in its infancy. Since the implementation of risk monitoring by the Shanghai Food and Drug Administration in 2005, the first problem is how to deal with a large amount of monitoring data, to fit the actual situation of pollution of certain pollutants in food, and then to carry out probability assessment. Around 2007, WHO and FAO applied @RISK software to build risk assessment models in multiple risk assessment reports. Therefore, in 2007, Shanghai Food and Drug Administration took the lead in purchasing and applying @RISK 5.0 software in mainland China, and carried out a series of quantitative risk assessments, such as risk assessment of nitrite pollution in cooked meat products, and heavy metal cadmium in food. The exposure assessment of pollution, the risk assessment of vomiting toxin contamination in wheat flour products, and the risk assessment of Bacillus licheniformis contamination in rice have received good results and completely solved the above problems and difficulties. After using @RISK 5.0 to obtain a lot of research results, the Shanghai Food and Drug Administration decided to continue to use and upgrade its version. When Palisade launched the DTS software package in 2011, it upgraded to DTS 5.7, so that it can use it. More powerful features for further risk assessment and decision analysis of microbial contamination in foods, such as risk assessment of Vibrio parahaemolyticus contamination in seafood, and risk assessment of Listeria monocytogenes contamination in refrigerated sales of ready-to-eat foods, Both have achieved good evaluation results and obtained effective and necessary risk management recommendations.
@RISK's Application in Food Safety Inspection Analysis of Expo 2010
In 2008, Shanghai Food and Drug Administration used @RISK to conduct an exposure assessment of nitrite pollution in cooked meat products in Shanghai, which is a very typical case of risk analysis using @RISK. At the time, the 41st World Expo, which was watched globally, was held in Shanghai in May 2010. The government attached great importance to the food safety guarantee of the World Expo. In 2008, Shanghai Food and Drug Administration began to conduct data monitoring and quantitative analysis and evaluation of nitrite pollution in cooked meat products in Shanghai. At that time, 370 pieces of cooked meat products were randomly sampled, and 16 samples were found to exceed the standard. The rate reached about 4%. Researchers at the Shanghai Food and Drug Administration have fitted a data analysis of the nitrite contamination data. It is found that the nitrite contamination in the excess sample meets an exponential distribution, and the researchers pass the meal. The survey found that the amount of cooked meat products consumed by ordinary residents per day is approximately a normal distribution of the left side truncation.
Based on the initial data, the β distribution is used to indicate the possibility of the consumer taking food samples that may exceed the standard in actual consumption. Then the researchers use the @RISK software to simulate sampling 10,000 times and multiply the three variables. It can fit the situation that may occur in real life and obtain the exposure of nitrite that may be ingested by ordinary Shanghai residents through cooked meat products. Through the final exposure results, the Shanghai Food and Drug Administration found that this data has more than the risk of acute nitrite poisoning threshold of 0.3g / time, but also the possibility of exceeding the nitrite ADI value (daily allowable intake) . With these exposure assessment results, Shanghai Food and Drug Administration can propose corresponding management countermeasures based on these conclusions, such as banned use of nitrite in the catering service industry, which can avoid cooked meat caused by improper use or other factors. The risk of excessive nitrite and excessive residue of the product fundamentally eliminates the possibility of nitrite poisoning.
@RISK found a new research and analysis law for Shanghai Food and Drug Administration
The Shanghai Food and Drug Administration is very satisfied with the cooperation with Palisade Risk and Decision Analysis @RISK software, and its powerful scientific risk analysis function, especially the DTS software package function. If some domain risk analysis problems are solved by feelings or subjective world experience before using the software, then after using @RISK software, Shanghai Food and Drug Administration has eliminated the traditional backward risk analysis and evaluation. Ways, and can find some micro-laws in the field of food safety, such as the laws and risks related to physical and chemical pollution or biological pollution, which is very important for the public's food safety.
