What is the metronidazole colloidal gold rapid detection card in poultry eggs?

Metronidazole Colloidal Gold Rapid Detection Card in Poultry Eggs is a rapid detection product specially designed for the detection of metronidazole residues in poultry eggs. Metronidazole, as a nitroimidazole antibiotic, has been widely used to treat infectious diseases in poultry, but excessive or improper use may lead to its residues in poultry eggs, threatening consumer health. Therefore, rapid and accurate detection of metronidazole residues in poultry eggs is of great significance to ensure the food safety of poultry eggs.

The core of this detection card is based on colloidal gold immunochromatography technology. Its principle is: the metronidazole antibody labeled with colloidal gold is fixed in the detection line area, and the quality control line area is coated with sheep anti-mouse IgG antibody. During testing, the sample solution (such as egg homogenate) is dropped into the sample well and chromatographed along the test strip under capillary action. If the sample contains metronidazole, it will bind to the colloidal gold-labeled antibody to prevent it from binding to the metronidazole antigen of the detection line. At this time, the detection line does not show color; if the sample does not contain metronidazole, the labeled antibody will bind to the detection line antigen, and the color development is positive. By comparing with the quality control line, the result can be judged.

Compared with traditional detection methods (such as high performance liquid chromatography, mass spectrometry), the colloidal gold rapid detection card has significant advantages: first, the speed is fast, the whole detection process only takes 10-15 minutes, no need for complex pretreatment; secondly, it is easy to operate, no professional equipment and personnel training are required, and grass-roots supervisors or enterprises can quickly start self-testing; secondly, it is low-cost, low-cost test strips, suitable for large-scale screening; at the same time, its sensitivity is high, and it can detect as low as ng-level metronidazole residues, meeting the requirements of food safety standards.

At present, this detection card is widely used in poultry egg production, processing, circulation and other links. Market regulators can quickly detect problem products through random inspections, manufacturers can conduct self-inspections before leaving the factory to ensure product safety; consumers can also enhance their confidence in the quality of poultry egg products by understanding detection technology. With the continuous optimization of technology, metronidazole colloidal gold rapid detection cards in poultry eggs will play an increasingly important role in food safety supervision, providing strong support for guarding the "safety on the tip of the tongue".
