HAMILTON, Canada, Nov 23 2021 (IPS) – The has become the main driver of antimicrobial resistance (AMR) and drug-resistant infections that threaten human health and the global economy.
Given that development, the UN designated November 18-24 as , to remind us all to handle antimicrobials with greater care.
Antimicrobials – which range from antibiotic and antiviral medicines to disinfectant and antiseptic chemicals – help prevent or treat human, animal and plant infections and have contributed immensely to health and progress worldwide.
Now, however, common antibiotics, as well as first-line antimicrobials for infectious diseases such as HIV and malaria, are becoming .
The World Health Organization reports that die from drug-resistant diseases every year. If this threat continues unchecked, and .
Most worrying, . Increasingly, multilateral organizations and national governments are adopting measures to reduce unnecessary antimicrobial use by humans, including in our food chain.
From 2000 to 2015, human consumption of antibiotics , led by low- and middle-income countries (LMICs) where GDP has risen in parallel with antibiotic use, overuse and misuse.
Meanwhile, antimicrobial use in animal farming is nearly triple that of human consumption and is on track to reach by 2030 as producers work to reduce infection and increase animal growth.
is limited, but the presence of resistant bacteria has been detected on from all world regions, indicating that food likely is contributing to greater AMR.
The excessive use of antimicrobials in humans, animals, and plants also puts environmental health at risk. But via soil, air, or water receives relatively little attention as an .
Depending on the drug, humans and animals can excrete waste with up to still active, which can end up untreated in the environment.
Unsafe disposal of antimicrobials and wastewater from hospitals, , are recognized as hotspots for the introduction and evolution of more resistant strains (i.e., ).
This pollution can consequently compound human AMR exposure through contaminated soils and water supplies that sustain our environment, or are used to produce food, for drinking, cleansing and recreation.
Increasing access to safe water, sanitation and hygiene (WASH) are the primary environmental interventions .
However, current statistics paint an alarming picture of whether these efforts are enough to address environmental risks, as does not have access to safe water and just over . Of particular concern are large swathes of .
At current rates of progress, universal WASH and wastewater treatment , which highlights the need to put into place now additional measures that protect environmental waters from these AMR exposure pathways.
Environmental waters are and their protection, therefore, is critical in AMR stewardship. Environmental waters refers to the world’s diverse natural and man-made water bodies, ranging from wetlands that shelter wildlife and nurture local ecosystems, to groundwater and surface waters from which we draw supplies or discharge wastewater into.
One could argue that environmental water AMR protection is inherent in .
But wastewater treatment from a major contributor to environmental pollution – agriculture – tends to be overlooked, despite the facts that this industry uses the largest amount of antimicrobials, 70% of , and discharges the majority of its wastewater and runoff untreated into the environment.
The combination of poor WASH coverage and inadequate domestic, industrial, and agricultural wastewater treatment puts from polluted environmental waters at greater risk of AMR exposure and infection.
Safeguarding environmental waters represents a major void in current AMR stewardship efforts, despite water protection being recognized in 2018 as the “” to reducing environmental AMR pollution.
The UN should support surveillance, regulation and enforcement of water and land protection legislation and development of AMR-related water quality standards – to prevent and mitigate environmental AMR risks, as well as equitably address human, animal, and environmental AMR threats.
