The Misconception Behind Anti-Bacterial Soaps: Why People Believe In Their Efficacy

Regular handwashing is a widely promoted public health practice aimed at reducing the number of pathogens on our hands, which include viruses, fungi, and bacteria. However, many people mistakenly believe that anti-bacterial soaps are more effective in killing these germs. This belief has led to a significant market for hand sanitizers that claim to eliminate a variety of harmful pathogens, often resulting in misleading claims. One notable case is the Purell company, which is currently under scrutiny for making unfounded claims about the efficacy of their products in preventing diseases such as Ebola and MRSA.

The Role of Fear in Advertising

People are naturally afraid of germs, and advertisers often exploit this fear to sell products. Despite this fear, the vast majority of germs we come into contact with can be easily removed with ordinary soap and water. According to the Food and Drug Administration (FDA), ordinary soaps are sufficient to kill the majority of germs we encounter in our daily lives.

Scientific Warnings and FDA Bans

Healthcare professionals and scientists have raised concerns about the potential risks of developing antibiotic-resistant bacteria due to the consistent use of anti-bacterial soaps. These concerns have been heightened by an FDA ban on the ingredient triclosan in over-the-counter (OTC) antibacterial soaps. Triclosan, commonly found in many anti-bacterial products, is considered to carry unnecessary risks that outweigh any potential benefits.

The FDA Guidance

The FDA and the Centers for Disease Control and Prevention (CDC) recommend frequent hand washing with plain soap and warm water as the most effective method for preventing illness and avoiding the spread of germs. This guidance is based on scientific evidence and public health best practices.

Case Studies: Cruise Ships and Proper Hygiene Practices

Cruise ships have recognized the importance of proper hygiene practices and have implemented new and improved measures to enhance their passengers' safety. For instance, new ships and older ships have been retrofitted with hand washing stations at all entrances to the Lido Buffet, a popular eatery on cruise ships. Passengers are advised to use these stations to clean their hands regularly.

In situations where access to clean water is limited, using an alcohol-based hand wipe followed by a paper towel is recommended. The goal is to remove the germs rather than trying to kill them. This approach is more effective in reducing the risk of illness and disease spread compared to using hand sanitizers.

Conclusion

The belief in the efficacy of anti-bacterial soaps is a widespread misconception that has been fostered by misleading advertising. However, the scientific consensus and public health guidelines clearly recommend the use of ordinary soap and water for effective hand hygiene. By understanding the true nature of germs and the best methods for preventing illness, we can adopt better hygiene practices and contribute to the overall health and safety of our communities.
