Abstract Objective: To analyze the contamination status of perfluorinated compounds (PFCs) in pork and its by-products on the market and to assess the health risk associated with consumption of them. Methods: A total of 25 PFCs in 85 samples of 7 kinds were determined by liquid chromatography-tandem mass spectrometry to explore their pollution characteristics and assess their potential health risks based on hazard ratio (HR). Results: PFCs were widely detected in pork and its by-products on the market at concentrations of 1.18%–55.29%. Perfluorobutyric acid, perfluorononanoic acid, and perfluorooctane sulfonic acid (PFOS) were the main pollutants. The main pollutant in pig liver was PFOS, and its total PFC content was the highest (43.14 μg/kg). Conclusion: A total of 13 PFCs were detected at low levels in the 85 samples. The health risk assessment showed that they would not cause harm to the health of adults and children.
