Occurrence and Dietary Exposure of Legacy and Emerging Per- and Polyfluoroalkyl Substances in Preprepared Meat and Aquatic Dishes — China, 2025

What is already known about this topic?The increasing consumption of preprepared dishes in China has raised public health concerns regarding potential exposure to per-and polyfluoroalkyl substances (PFASs). What is added by this report?Trifluoroacetic acid was the predominant PFAS in all samples, while long-chain PFASs were mainly detected in aquatic foods.A conservative scenario-based dietary exposure assessment showed that the estimated daily intake of total PFASs ranged from 1.14 to 98.63 ng/kg body weight/day across various preprepared dishes.What are the implications for public health practice?Current PFASs exposure from preprepared meat and aquatic dishes poses a low health risk for consumers, but continued monitoring and risk assessment remain necussary.
