To investigate quinolone antibiotic residues in fresh/frozen aquatic animals in Shanghai and assess dietary intake and health risks for local adults.
A total of 8 857 samples were collected from breeding, circulation and catering links in Shanghai during 2017-2024. Fourteen quinolone antibiotics were detected by high performance liquid chromatography-tandem mass spectrometry. Combined with “2023 Shanghai Residents’Diet and Health Status Monitoring”data, point and probability estimation were used to evaluate health risks.
The total detection rate of quinolone antibiotics was 26.40% with a total over-limit rate of 4.36%. Enrofloxacin (including ciprofloxacin) had the highest detection rate (26.21%) and over-limit rate (3.91%), while other quinolones had detection and over-limit rates <1%. Top 3 for highest average total quinolone antibiotic residues: freshwater fish, freshwater shrimp, marine fish. Point assessment showed food safety indexes <1 for both general and highly exposed populations, indicating low health risks. Probability assessment revealed P50 and P95 exposure levels of enrofloxacin (including ciprofloxacin) were 1.89 ng/(kg·bw·d) and 139.00 ng/(kg·bw·d), respectively.
Enrofloxacin (including ciprofloxacin) was the main detected quinolone in Shanghai’s fresh/frozen aquatic animals, with freshwater fish more contaminated. However, health risks of quinolone intake via these products for Shanghai adults were relatively low.
