A new rapid avian influenza virus detection system has been introduced at the Tianjin Broiler Production Base. According to the technicians, this device can identify whether broilers are infected with the virus in just 1 hour and 54 minutes, significantly improving the efficiency of disease monitoring.
The compact machine was recently observed in the laboratory of Kangdi Wanda (Tianjin) Co., Ltd. in Xiqing District. The company's representative noted that although the device is small in size, it was imported from abroad at a cost exceeding 400,000 yuan. Its full name is "Fluorescence Reverse Transcription-Polymerase Chain Reaction Detector," commonly known as a fluorescence PCR detector, specifically designed for avian influenza testing.
The dark blue device is about the size of a printer, with a small drawer beneath it serving as the reagent compartment. Laboratory staff emphasized that despite its compact appearance, this instrument plays a critical role in determining whether broilers are infected with the virus. It is a key tool in ensuring food safety and preventing the spread of avian flu.
The detection process involves collecting body fluids from the broilers, such as nasal mucus, using a cotton swab. Then, a series of reagents—including lysis solution and other necessary chemicals—are added. The sample goes through seven steps of protein degradation and purification before being loaded into the detector. After 1 hour and 54 minutes, if a flashing light appears on the screen, it indicates a positive result, meaning the bird may be infected with avian influenza.
In such cases, the company immediately reports the findings to the relevant authorities and takes swift action by sealing all affected birds. This ensures that no potentially contaminated products reach the market, maintaining high standards of food safety and public health.
