What is the rapid detection card for beta-lactam drugs in poultry eggs?

As a common source of nutrition on the table, the safety of poultry eggs has always affected the hearts of consumers. In the production process of poultry eggs, some farmers may use beta-lactam drugs (such as penicillin, cephalosporins, etc.) to promote egg production or prevent diseases. If these drugs remain in excess of the standard in poultry eggs, they will not only affect the quality of egg products, but also pose potential threats to human health, such as causing allergic reactions or drug resistance problems. In order to quickly and accurately detect such drug residues in poultry eggs, the rapid detection card for beta-lactam drugs in poultry eggs came into being.

So, what is the rapid detection card for beta-lactam drugs in poultry eggs? In simple terms, it is a rapid detection product based on immunochromatography technology. Its core principle is similar to that of early pregnancy test strips commonly used in hospitals: by coating the test strip with specific antibodies and quality control lines, when the sample (such as egg-like extract) drops into the test strip, if the sample contains beta-lactam drugs, it will bind to the colloidal gold-labeled antibodies, preventing it from binding to the antibodies of the test strip detection line, thus presenting different color rendering results on the test strip - if both the test line and the quality control line are colored, it indicates that the sample contains such drugs; if only the quality control line is colored, the sample is qualified.

The advantages of this detection card are very prominent. The first is the speed, the entire detection process usually only takes 10-15 minutes, without the need for complex instruments and equipment, and the operator can get started after simple training; secondly, the convenience is strong, the sample pre-processing is simple, and professional laboratory conditions are not required. It can be used directly in farms, wholesale markets, testing institutions and other scenarios; secondly, it has high accuracy, and its detection sensitivity can meet the requirements of national standards, which can effectively distinguish qualified and exceeding samples; finally, it has low cost. Compared with traditional high-performance liquid chromatography and other detection methods, the single-batch detection cost of the rapid detection card is lower, which is suitable for large-scale screening.

In practical applications, the rapid detection card for beta-lactam drugs in poultry eggs plays an important role. For poultry egg production enterprises, it can be used as a preliminary screening tool when purchasing raw eggs to avoid unqualified eggs from entering the production process; for market supervision departments, it can quickly conduct random inspections of poultry eggs in circulation and find problem products in time; for export enterprises, it can be used as a safety guarantee before product export to ensure compliance with the residue standards of importing countries.

It can be said that the rapid detection card for beta-lactam drugs in poultry eggs is like an "instant detective". On the premise of not affecting the freshness of eggs, it can quickly "check" the safety of poultry eggs, so that consumers can eat more at ease, and also provide strong technical support for the healthy development of the poultry egg industry.
