The study examined the presence of antibiotic residues in milk from five farms in Keraniganj, Dhaka, focusing on commonly used antibiotics like oxytetracycline and fluoroquinolones.
Using a reliable RP-HPLC method, the study found that oxytetracycline was present in 90% of milk samples, with levofloxacin (66%), enrofloxacin (64%), and ciprofloxacin (62%) also detected.
While 30% of oxytetracycline-positive samples exceeded the maximum residue limits (MRL), no samples exceeded the MRL for the other antibiotics, indicating low human health risks, though children might be more vulnerable to prolonged
