Antimicrobial Resistance: What is AMR?

Antimicrobial resistance (AMR) is a complex, global issue driven by many interconnected factors. But what causes AMR? AMR arises when microorganisms (such as bacteria, fungi, viruses, and parasites) mutate, following repeated or prolonged exposure to antimicrobial drugs (such as antibiotics, antifungals, antivirals, antimalarials, and anthelmintic drugs). The global misuse and overuse of antimicrobials is accelerating this process, causing superbugs such as MRSA.

It is not just about overuse of antimicrobial drugs though. Pharmaceuticals contaminate our water supply, either from production facilities or through human or animal medication consumed and excreted. In addition, antimicrobial medication is often unused and disposed of in landfill, allowing pharmaceuticals to contaminate our water supply via ground water.

MDRO – Multidrug Resistance Organisms

The effluent produced by some pharmaceutical manufacturing facilities has been described as ‘a reservoir for the development of AMR’. Research shows that Active Pharmaceutical Ingredients (APIs) and other pharmaceutical residues within the wastewater from these facilities have adverse effects on aquatic life and greatly increase the prevalence of multidrug resistant organisms (MDRO) such as MRSA (Methicillin-Resistant Staphylococcus Aureus).

Pharmaceuticals in the Environment (PiE) and AMR

Pharmaceuticals in the Environment (PiE) and Antimicrobial Resistance (AMR) are closely interconnected. Increasing levels of pharmaceuticals are being detected in waterways due to inadequate wastewater treatment, run-off from intensive farming and sometimes even irresponsible disposal. This pollution of surface and ground water impacts water quality, drinking water supply, aquatic life, and also facilitates AMR.

Environmental Pollution from Antimicrobials

Of course, the utilities, pharmaceutical manufacturers and agriculture industries make every effort to remove the active pharmaceutical ingredients (API) from the water. But existing water treatment processes are not entirely effective at pharmaceutical pollutant removal and harmful traces are left behind. This gives us all a mild dose of antibiotics, antifungal or antiviral medication through our drinking water, exacerbating the worldwide AMR problem.

With enhanced technology, water analysis is improving and water testing is becoming more refined. Alongside this, regulations are getting stricter in an effort to improve water quality to reduce AMR. This is driving the need for new water treatment technology which can tackle the problem of environmental pollution from antimicrobials.

How Do You Address AMR?

The main drive for tackling AMR is to restrict the use of antimicrobials on a worldwide basis. This means regulating pharmaceuticals for both human and veterinary purposes. On top of these controls, we also need to clean up our water and improve water quality worldwide.

The serious consequences of PiE have led to increasing pressure on the pharmaceutical industry to take action. On top of their pro-active approach, one of the recommendations outlined in a recent UN report to tackle antimicrobial resistance, was to introduce stricter regulatory systems for responsible handling of antimicrobials.

The production of an ever-increasing range of pharmaceutical products results in wastewater with a complex composition.

Improving Water Quality

The complex composition of pharmaceutical wastewater is notoriously difficult to treat with existing water treatment technologies. It is particularly hard to treat pharmaceutical wastewater to low levels of parts per trillion in compliance with regulation from industry authorities.

Failure to comply with regulations can result in a loss of permit, operational downtime, limited production volume and severe fines. We need to pull together to solve this problem, supporting our pharmaceutical and utility industries.

A New Water Technology Solution is Needed

As traditional municipal wastewater treatment plants are not designed to tackle such varied and persistent compounds, manufacturers are challenged to remove the pharmaceutical residues, including antibiotics, prescription and non-prescription drugs at source.

But many existing treatment processes are not able to remove the organic pollutants. And the ones that can remove these specific organics, such as ozonation, have been brought into question by REACH for the environment impact of ozone itself, which is under assessment for being an Endocrine Disrupting Chemical (EDC).

This has forced the development of new environmentally friendly water treatment solutions to work alongside existing treatment processes.
