Heavy Antibiotics in Chickens: Food Safety & Health Risks
Antibiotic Overuse in Bangladesh’s poultry Industry Poses Growing Threat

The Scale of the Problem
A new study reveals a deeply concerning trend: widespread and often inappropriate antibiotic use in Bangladesh’s poultry sector. Researchers examining 340 commercial chicken farms across seven districts found that a staggering 93% utilized antibiotics during production. This practice isn’t uniform, however. Meat-type chicken farms – specifically those raising broilers and Sonali breeds – are driving the majority of the overuse, with 78% and 67.2% reporting antibiotic use respectively, substantially higher than the 41.3% observed in egg-laying farms.
The study, published on Nature.com, highlights that broiler farms are three times more likely to exhibit poor antimicrobial practices compared to layer farms. Broiler farmers frequently administer multiple classes of drugs, even within the relatively short production cycles characteristic of meat-type chickens.
Critical Antibiotics in Routine Use
The research uncovered the extensive use of antibiotics deemed “Highest priority Critically Important Antimicrobials” by the World Health organization (WHO) for human health. Nearly half of the farms used fluoroquinolones, followed by tetracyclines and sulfonamides.Alarmingly, colistin – a last-resort drug for treating severe human infections – was still used on approximately 4% of farms, despite WHO guidance urging restricted use to preserve its effectiveness.
The reasons behind this overuse are multifaceted. Over a third of farmers reported using antibiotics for disease prevention, while nearly half administered them to chicks on their very first day. This prophylactic use, combined with a lack of targeted treatment, contributes significantly to the problem.
Knowledge Gaps and Outdated Practices
A important barrier to addressing this issue is a lack of awareness. The study found that only about one-third of farmers understand the concept of antimicrobial resistance (AMR). Furthermore, many farmers rely on advice from drug sellers or feed dealers rather than qualified veterinarians. Just 22% consistently consult with veterinary professionals, while nearly a third never do.
Interestingly, the study also revealed a correlation between experience and misuse. Farmers with over a decade in the industry were more likely to misuse antibiotics than newer entrants, suggesting that outdated practices are deeply ingrained within the sector.
The Risks to Public Health
Researchers warn that the indiscriminate use of antibiotics is fueling the rise of multidrug-resistant bacteria – not only in poultry but also in farm sewage and even among individuals handling chickens. This poses a direct risk to consumers and public health. The presence of antimicrobial residues in meat products further exacerbates the problem, potentially harming human health upon consumption.
The consequences of unchecked antibiotic resistance are severe. Infections that were once easily treatable are becoming increasingly arduous, and even deadly. Without urgent intervention, the misuse of antibiotics in bangladesh’s meat-type chicken farms threatens to accelerate this crisis and undermine both animal and human health.
