High prevalence of low-concentration antimicrobial residues in commercial fish: A public health concern in Bangladesh

A study in Bangladesh found that antibiotics used in commercial fish farms raise concerns about antimicrobial resistance (AMR) and environmental contamination. The study used Thin Layer Chromatography to detect antimicrobial residues in four fish species, with the highest prevalence observed for Ciprofloxacin in Tilapia, Oxytetracycline in Pabda, and Chlortetracycline in Tilapia. The highest Hazard Quotient (HQ) was for Enrofloxacin in Climbing perch. Further research is needed to understand antimicrobial bioaccumulation, indirect exposure sources, and environmental contamination.
