The quality and safety of agricultural products is closely related to the lives of the citizens. In order to ensure the safety of the people, how can relevant departments test the quality and safety of agricultural products? On August 4th, at the news ventilation meeting of Sichuan Province's agricultural product quality and safety and investment safety situation in the first half of 2022, Lin Fanglong, director of the Sichuan Agricultural Products Quality and Safety Center, answered.

"The quality and safety testing of agricultural products is an important technical means and measures to evaluate the quality and safety of agricultural products, the hidden dangers of the risk, grasp the changes in trends, and provide a basis for decision -making." Lin Fanglong said that the agricultural product quality inspection agencies determine the agricultural products (beasts) based on technical documents such as standards. The content of risk factors such as drug residues, prohibited drugs, heavy metals and biological toxins determine whether it meets the requirements of national food safety limited standards and whether agricultural products are safe.

"Sichuan Province's agricultural product quality and safety detection mainly uses quantitative testing and fast detection." He introduced that quantitative testing is mainly used to detect large -scale precision instruments, mainly used to detect agricultural (animal) drug residues, prohibited drugs, biological toxins, heavy metals Content, etc.

The province's agricultural and rural departments have annual quantitative samples of various types of agricultural products reached 130,000 batches. The results obtained from quantitative detection are high, but there are many pre -processing process, long detection time, high detection costs, and also requires requirements for detection environmental conditions. It is mainly suitable for provincial and cities, counties, county agricultural product quality inspection professional institutions.

Compared with quantitative testing, fast detection has the characteristics of simple operation, low cost, and fast speed. It is an important technical means for the quality and safety supervision of the grass -roots first -line agricultural products. "At present, the fast -testing methods used in our province are mostly enzyme suppression and immunology methods, which are mainly used for pesticide residues, veterinary drug residues, and testing of prohibited substances."

With the promotion of low -toxic and low residues and downside, the changes in agricultural production and drugs, traditional fast inspection methods and technologies are difficult to find risk issues. This year, 10 counties (cities, districts), including Lizhuang City, Dayi County, and other 10 counties (cities, districts). Compared with the traditional enzyme suppression method, colloidal gold immunization speed testing , Make up for the test gap in conventional pesticides.

In the next step, it will combine the implementation of the qualified certificate and quality traceability system of the edible agricultural product commitment to meet the standards, and steadily promote the pilot piloting technology pilot technology of pesticide residual glum immunoscope. "By combining the rapid detection and quantitative testing of agricultural product quality and safety, build a network from provinces to villages and top -down agricultural product quality and safety testing networks, more timely and comprehensive grasp of the quality and safety of agricultural products, and listing agricultural products." Lin Fanglong said.
