In the production and circulation of poultry eggs, fipronil has been used as a highly effective insecticide to control pests in laying hens, but its residue has always been a concern in the field of food safety. Fipronil has high toxicity, and if the residue in poultry eggs exceeds the standard, it may pose a potential threat to human health. Therefore, the rapid and accurate detection of fipronil residues in poultry eggs has become an important part of ensuring food safety.

Fipronil Colloidal Gold Rapid Detection Card in Poultry Eggs is a new type of rapid detection product developed in response to this demand. It is based on colloidal gold immunochromatography, which labels specific antibodies with colloidal gold particles, and forms a color-developing band on the test strip through the specific binding reaction of antigens and antibodies, so as to realize the qualitative or semi-quantitative detection of fipronil residues.

The operation of the test card is very simple, without the need for complex equipment. Just add the processed egg sample (such as egg liquid and egg yolk) to the sample hole of the test card according to the instructions, and wait for a period of time (usually 10-15 minutes). The results can be judged by observing the strips that appear on the test strip: if both the test line and the quality control line show color, it means that the fipronil residue in the sample does not exceed the standard; if only the quality control line shows color, but the test line does not show color, it means that the residue exceeds the standard.

Compared with traditional detection methods, such as high performance liquid chromatography-mass spectrometry technology, the colloidal gold rapid detection card has significant advantages: the detection speed is fast, and the whole process only takes more than ten minutes; the operation threshold is low, and it can be started without professional training; the cost is relatively low, which is suitable for batch sample screening; high sensitivity, which can detect very low concentrations of fipronil residues. These characteristics make it widely used in the daily quality control of food enterprises, the rapid sampling inspection of market supervision departments, and the preliminary screening of scientific research institutions.

With the increasing attention of consumers to food safety, the rapid detection card of fipronil colloidal gold in poultry eggs is playing an increasingly important role. It not only helps companies detect faulty products in time to avoid entering the market, but also provides regulators with efficient law enforcement tools to protect consumers' "tongue safety" from the source.
