Introduction to Public Restroom Anxieties
Timestamp: [01:40]
Raj Panjabi and Noah Michelson delve into a common yet often overlooked anxiety: using public restrooms. They openly share their concerns regarding hygiene and the potential dangers lurking in these shared spaces. This conversation sets the stage for a deeper exploration into the science of germs and practical strategies to navigate public bathrooms safely.
Meet the Expert: Jason Tetrow

To provide authoritative insights, the hosts invite Jason Tetrow, widely known as the "Germ Guy." With his extensive background in microbiology and authorship of two books on germs, Tetrow offers a credible perspective on the realities of public restroom hygiene.
How Germy Are Public Restroom Toilet Seats?
Timestamp: [03:15]
Jason Tetrow: "At any given time, about 50% of public toilet seats have some kind of poo germs on them, ranging from E. coli to more concerning pathogens like salmonella." ([03:22])
Tetrow explains that while toilet seats do harbor germs, the risk of transmission is often exaggerated. He clarifies that the contamination is primarily bacterial rather than viral, dispelling myths about sexually transmitted diseases (STDs) being transmitted through toilet seats.
The Poo Plume Phenomenon
Timestamp: [04:33]
Noah Michelson: "We heard about the poo plume spraying particles up to six feet if the lid isn't shut. How real is this?" ([04:43])
Jason Tetrow: "The poo plume is indeed a real phenomenon. If the toilet lid isn't closed, particles can spray up to six feet, potentially contaminating nearby surfaces. However, aerosols generated from flushing can spread viruses further, contributing to viral contamination in the stall." ([05:31])
The discussion highlights the importance of closing the toilet lid before flushing to minimize the spread of germs. Tetrow emphasizes that while bacterial contamination can occur, viral particles like norovirus are of greater concern due to their ability to remain airborne longer.
Debunking STD Transmission Myths
Timestamp: [08:26]
Noah Michelson: "Can you really catch gonorrhea or syphilis from a toilet seat?" ([08:26])
Jason Tetrow: "No, you cannot catch STDs from toilet seats. The minimal effective dose required for these infections is not achievable through casual contact with a toilet seat." ([08:32])
Tetrow reassures listeners that fears surrounding STD transmission via toilet seats are unfounded, focusing instead on more plausible risks like gastrointestinal infections.
Best Practices for Public Restroom Hygiene
Timestamp: [10:55]
Noah Michelson: "What’s the best way to protect ourselves when using a public restroom?" ([10:55])
Jason Tetrow: "The most effective method is to use disinfectant wipes to clean the toilet seat before use. Allow the surface to dry fully to ensure maximum germ elimination." ([15:58])
Raj Panjabi: "I flush with my foot and run out of the stall." ([05:09])
The hosts and Tetrow agree on several practical strategies:
- Disinfecting the Seat: Use wipes to clean before sitting.
- Avoiding Touch Points: Minimize contact with high-touch areas like door handles and soap dispensers.
- Hand Hygiene: Thoroughly wash hands for at least 20 seconds, ensuring all surfaces are cleaned properly.
Hand Washing: The Cornerstone of Hygiene
Timestamp: [28:05]
Jason Tetrow: "Proper hand washing removes about 99.9% of germs. Hand sanitizers can further reduce any remaining microbes." ([35:40])
Tetrow underscores the importance of effective hand washing techniques, including using soap and water, covering all parts of the hands, and spending adequate time lathering. He also discusses the limitations of hand dryers, which can spread aerosols containing germs if hands aren't washed thoroughly.
Innovations and Solutions for Cleaner Restrooms
Timestamp: [44:21]
Noah Michelson: "Why don't we have more foot-operated flushers and door handles?" ([45:37])
Jason Tetrow: "Foot pedals can significantly reduce germ transmission by eliminating the need to touch surfaces with hands. Additionally, non-touch systems for sinks and dispensers are becoming more prevalent and should be encouraged." ([44:32])
The conversation explores potential technological advancements to enhance restroom hygiene, advocating for hands-free mechanisms to minimize contact and germ spread.
Conclusion and Key Takeaways
Timestamp: [49:59]
The episode wraps up with a "Better in Five" segment summarizing the main points:
- Restrooms Have Germs, But They're Not Usually Dangerous: Most germs in public restrooms won't make you sick.
- Disinfectant Wipes Over Barriers: Cleaning the toilet seat with wipes is more effective than using paper seat covers.
- High-Touch Surfaces Are Germier: Handles, soap dispensers, and hand dryer switches harbor more germs than toilet seats.
- Avoid the Poo Plume: Close the lid before flushing and exit the stall promptly to minimize exposure.
- Thorough Hand Washing Is Essential: Spend at least 20 seconds washing with soap to remove germs effectively.
Notable Quotes:
- Jason Tetrow: "The lid contains droplets, but aerosols can spread viruses much further." ([05:31])
- Raj Panjabi: "I never put my bare ass on a toilet seat. Once I did, and took four showers after." ([13:01])
- Noah Michelson: "Most germs are not there to hurt us. If you feel comfortable just sitting on a toilet seat after you've wiped it down, go for it." ([26:37])
Final Thoughts: This episode of Am I Doing It Wrong? provides a comprehensive look into public restroom hygiene, blending scientific insights with practical advice. Jason Tetrow effectively demystifies common germ-related fears, empowering listeners to navigate public restrooms with confidence and informed caution.
