MADRID, Apr 13 2022 (IPS) – People around the world are unknowingly being exposed to water laced with antibiotics, which could spark the rise of drug-resistant pathogens and potentially fuel another global pandemic, warns a new report.
The , elaborated by the United Nations Environment Programme (), found that, globally, not enough attention is being focused on the threat posed by antimicrobial resistance with most antibiotics being excreted into the environment via toilets or through open defecation.
Already in 2015, 34.8 billion daily doses of antibiotics were consumed, with as active substances. Since then the amount of daily consumed antibiotics has been increasing considerably.
80% of wastewater, untreated
While 80 percent of wastewater in the world is not treated, even in developed countries treatment facilities are often unable to filter out dangerous bugs.
This could breed superbugs that can evade modern medicine and trigger a pandemic, the report’s authors warned.
In 2019, antibiotic-resistant infections were linked to the deaths of nearly 5 million people. Without immediate action, those infections could cause up to 10 million deaths per year by 2050, the report found.
“Another pandemic is hiding in plain sight,” the report said. “The consequences of the continuing development and spread of antimicrobial resistance could be catastrophic.”
What are antimicrobials?
Antimicrobials are agents intended to kill or inhibit the growth of pathogens. They include antibiotics, fungicides, antiviral agents, parasiticides, as well as some disinfectants, antiseptics and natural products.
Antimicrobial resistance occurs when microbes, such as bacteria, viruses, parasites and fungi evolve to become immune to the drugs to which they were previously susceptible, explains the report.
The more microbes are exposed to pharmaceuticals, the more likely they are to adapt to them.

What to do?
According to the report, this global threat can be tackled by curbing the release of antibiotic-tinged pollution, including through improved wastewater treatment and more targeted use of antibiotics – too often these drugs are used when they need not be.
The report also called for enhanced environmental governance and national action plans to limit the release of antimicrobials.
UNEP urged countries to embrace the , which is centred on the idea that human and animal health are interdependent and linked to the health of the ecosystems in which they co-exist.
The strategy, for example, calls on countries to “limit deforestation, which often brings humans face-to-face with virus-carrying wild animals, giving pathogens a chance to jump species.”
The COVID-19 pandemic provides lessons learned, one of which is the need to prevent and tackle various health threats concurrently, especially their environmental dimensions, said the report.
Five main sources

According to the UNEP , five main pollutant sources contribute to the development and spread of antimicrobial resistance. They are:
