    Abstract:
    A simple, rapid and accurate detection method for the authentication of animal species is urgently required in the food detection field. The present study established a horse-specific polymerase chain reaction integrated with a lateral flow sensor assay (Horse-PCR-LFS) for the rapid detection of horse meat. In this test, a cytb gene sequence of horse was amplified using PCR, the PCR amplicon was checked with the lateral flow sensor assay, and the result of the sensor can be read within 2-3 min by the naked eye. The detection limit of the test was up to 0.01% horse meat in artificially adulterated meat mixtures, the assay also successfully detected horse DNA in various commercial food samples. As a rapid and user-friendly molecular detection tool, this test provides an accurate detection format for the identification of horse and offers solutions to problems related to animal meat adulteration and animal-origin food safety and traceability.
