Abstract Proper labeling of meat products is critical for consumers who want to avoid specific meat species for cultural or religious reasons. Herein, we developed a convenient strand-displacement DNA polymerase induced isothermal circular amplification (SDPICA) fluorescence sensor for detection of undeclared pork component in meat products. The proposed assay was performed at 37 °C for 20 min with no cross-reactivity, and could detect 1 pg of pork DNA per reaction. The limit of detection of the SDPICA assay was as low as 0.1% pork in 30 mg multi-component meat mixtures. This assay would contribute to the quality control of meat products in food industry.
