A recent study of 340 commercial chicken farms across seven districts in Bangladesh has highlighted extensive antibiotic use in the sector, particularly among meat-type chickens. Broiler farms reported 78% antibiotic usage, while Sonali farms reached 67%, compared with 41% in egg-laying operations.
The research identified frequent administration of multiple drug classes in broiler production, despite short production cycles. Medicines listed by the World Health Organization as “Highest Priority Critically Important Antimicrobials” were commonly used. Fluoroquinolones appeared in nearly half of farms, followed by tetracyclines and sulfonamides. Colistin, a last-resort antibiotic for humans, was reported in approximately 4% of farms.
Farmers cited disease prevention as a key reason for antibiotic use, with nearly half administering drugs to day-old chicks. Only a third demonstrated awareness of antimicrobial resistance. Guidance was often sought from drug sellers or feed suppliers, with just 22% regularly consulting veterinarians and nearly a third never doing so. More experienced farmers were more likely to misuse antibiotics than newer entrants.
Researchers warn that widespread antibiotic use drives multidrug-resistant bacteria in poultry, farm effluent, and among handlers, creating risks for public health. Residues in meat products could further impact consumers. The study emphasises the need for targeted interventions to limit antibiotic misuse and protect both animal and human health.
