Doctor Warns: That ‘Pink Slime’ in Your Bathroom Might Be a Bigger Problem Than You Think
Think the rosy residue by your sink or tub is just a harmless mess? You may want to reconsider.
A doctor has gone viral on TikTok after revealing the truth behind the mysterious ‘pink slime’ found in many bathrooms—and why it could signal something more serious.
Dr. Karan Raj recently shared a video in response to a user who ended up hospitalized after ignoring the “pink mold” in their college dorm shower.
Reacting to the clip, Dr. Karan clarified: “If you’ve spotted this pink gunk in your bathroom, it’s not mold—it’s a type of bacteria.”
He explained that the pink film you often see around drains, tiles, or faucets isn’t mold at all. It’s actually a bacteria called Serratia marcescens.
And according to him, this bug can “spew hot pink all over your bathroom.”

“This particular bacteria thrives in damp, humid environments and feeds on fatty residues like those found in soaps and shampoos—that’s why it tends to settle in your bathroom,” he explained.
According to Infectious Disease Advisor, the bacteria is widespread and doesn’t just stick to households. “It exists in soil, water sources, vegetation, and even animals.”
“In domestic and medical settings, it commonly shows up in the damp corners of showers or sinks, often noticeable because of the reddish pigment it produces, known as prodigiosin.”
While the doctor reassures that this microbe is “mostly harmless” for the average person, even if exposed, he does give a warning.
“You still want to keep it away from your eyes or any open cuts,” he cautions.
For individuals with compromised immune systems, or those who are critically ill or hospitalized, contact with this bacteria can become far more dangerous. Infectious Disease Advisor notes that it’s “frequently resistant to multiple antibiotics, which can make treatment more challenging.”

Dr. Karan explains that for those with weakened immune systems, Serratia marcescens can lead to infections in the digestive tract, urinary system, and even the lungs.
He adds: “If your home stays damp enough for pink slime to keep forming, chances are, other unwanted growths—like actual mold—might also be thriving, potentially triggering allergies or breathing problems.”
So, what’s the best way to stop this slime from taking over your bathroom?

His top tip? Stop it before it starts. “Rule number one of the Pink Slime Club: don’t let the bacteria settle in the first place.”
“Keeping it under control also helps stop other harmful molds from showing up.”
To keep this germ in check, Dr. Karan recommends making sure your bathroom stays dry and airy.
That means switching on the exhaust fan or cracking a window when the room gets steamy.
And of course, your best defense? A solid cleaning routine.
Grab a reliable disinfectant and give your bathroom a thorough scrub to keep the bacteria from taking hold.
