Background of Pesticide Residue Rapid Tester Pesticides enter food, vegetables, fruits, fish, shrimp, meat, eggs and milk, causing food contamination and endangering human health. Ordinary organochlorine pesticides have a slow metabolic rate in the human body and have a long accumulation time. Organic chlorine residues in the human body are mainly concentrated in fat. For example, the content ratio of DDT in human blood, brain, liver and adipose tissue is 1:4:30:300; dieldrin is 1:5:30:150. Because pesticide residues are very harmful to humans and organisms, all countries apply strict management of pesticides and regulate the tolerance of pesticide residues in foods. If Japan implements a registration system for pesticides, the government will restrict or prohibit sales and use once it is confirmed that a certain pesticide is harmful to humans and animals.
The World Health Organization and the Food and Agriculture Organization of the United Nations (WHO/FAO) define the pesticide residue limit as the maximum concentration of pesticide residues formed in food and feed after the direct or indirect use of pesticides in accordance with the Good Agricultural Practice (GAP) specification. . Firstly, according to the assessment of the toxicity of pesticides and their residues, in accordance with the Good Agricultural Regulations promulgated by the State and the safe and rational use of pesticides specifications, to meet the needs of prevention and control of various pests and diseases in the country, under strict technical supervision, under the premise of effective prevention and control of pests and diseases, The series of residual data obtained has a representative higher value. Its direct role is to limit pesticide residues in agricultural products and protect citizens' health. With the integration of world trade, the maximum residue limit of pesticides has also become an important technical barrier among trading nations.
Topp Instrument's independent R&D and production of pesticide residue rapid tester adopts the enzyme inhibition rate method to rapidly detect the pesticide residue in the sample. The sensitivity is high, and the minimum detection limit for pesticides such as methamidophos and dichlorvos is better than the national standard.
