Pharmaceutical effluent: a critical link in the interconnected ecosystem promoting antimicrobial resistance

Area of Science:

• Environmental Health
• Microbiology
• Global Health Security

Background:

• Antimicrobial resistance (AMR) poses a significant global health threat, potentially causing extreme poverty and jeopardizing Sustainable Development Goals (SDGs).
• The environment, including water bodies, acts as a reservoir for antibiotic-resistant bacteria and genes, facilitating AMR propagation.
• The pharmaceutical industry's expansion contributes to environmental contamination through antibiotic-laden effluent.

Purpose of the Study:

• To review the detrimental effects of antimicrobial residues in pharmaceutical effluent on the development and spread of AMR.
• To highlight the lack of global regulations and interventions for pharmaceutical effluent concerning AMR.
• To advocate for an environmental risk assessment approach and collaborative efforts to address AMR.

Main Methods:

• This study is a review of existing research on pharmaceutical effluent and its role in AMR.
• Analysis of scientific literature detailing the impact of antibiotic residues on bacterial genomes and AMR.
• Examination of current national action plans and global regulatory frameworks related to AMR and pharmaceutical waste.

Main Results:

• Pharmaceutical effluent is a major source of antibiotic and antibiotic resistance gene contamination in the environment, creating hotspots for AMR.
• Inadequate treatment and disposal of pharmaceutical effluent lead to persistent environmental contamination, driving AMR.
• Existing national action plans often lack sufficient interventions for pharmaceutical effluent, and global regulations are absent.

Conclusions:

• Pharmaceutical effluent significantly contributes to the rise and spread of AMR, necessitating urgent attention.
• An environmental risk assessment approach with measurable indicators is crucial for countries manufacturing antibiotics.
• Collaborative efforts among policymakers, regulators, manufacturers, researchers, and civil society are essential for sustainable antibiotic production and preserving antibiotic effectiveness.
