The Survival of Superbugs: Overuse of Sanitizers and Disinfectants

With the increasing use of hand sanitizers and disinfectants, concerns have been raised about the emergence of superbugs. However, the concept of these tougher microorganisms developing resistance due to frequent exposure to sanitizers and disinfectants is a misconception. Instead, it appears that our overarching use of these substances might be inadvertently promoting the growth of microbial strains that are resistant to common cleaners.

Selective Breeding of Microbes

It is possible that humans are engaged in a form of selective breeding, where microbes that are resistant to the use of sanitizers and disinfectants are being selected for survival. While these sanitizers and disinfectants can sometimes be brutal in their effectiveness, they kill bacteria and viruses outright. Therefore, it is unlikely that they can develop resistance in a meaningful way.

Antibiotic Resistance: A Growing Concern

However, what we are seeing with microorganisms is a significant struggle with antibiotic resistance. Antibiotics have to work over time to combat bacterial infections, and their frequent use is leading to the evolution of more resistant strains. This has become a critical issue, with many infectious-disease specialists urging against the widespread use of antibiotics, even in animal feed.

Role of Wastewater Treatment

The wastewater treatment industry plays a crucial role in sanitizing household effluents and runoff from animal feedlots. This treated water often finds its way into natural water bodies, rivers, lakes, and oceans, and sometimes is used as a source of drinking water. It is important to note that the sanitization processes used in water treatment do not involve antibiotics; they are too expensive for such a role. Instead, biocides are utilized, which are cheaper and more widely available.

Impact of Overuse and Misuse

The overuse and misuse of biocides, especially when not warranted, can lead to the development of antimicrobial resistance. Just as some bacteria have become antibiotic-resistant, microorganisms are developing resistance to these disinfectants as a result of experimental and domestic use. Human fear of germs has led to unnecessary and sometimes excessive use of nonprescription antimicrobial products.

Long-Term Consequences of Biocide Mismanagement

The overuse of sanitizers and disinfectants can diminish their effectiveness, leading to a situation where they are less capable of performing their intended function. This mismanagement of biocides can be considered a form of facilitated suicide, as we are inadvertently damaging not only ourselves but also future generations. The lack of a license for these products only exacerbates the issue, making it easier for individuals to misuse them.

It is crucial to understand the balance between hygiene and the potential negative consequences of excessive disinfection. By using these products wisely and only when necessary, we can help prevent the emergence of superbugs and maintain the effectiveness of our sanitizing agents.
