People mistake it for mold.

It’s easy to tell if mold is growing in your bathroom: you notice the black stuff growing on the caulk that lines your bathtub or near the bottom of the hot and cold water handles on your sink. But have you ever seen a ring of pink slime accumulating around your sink drain or on the bottom of your shower curtain? Most people think it’s mold, but it’s actually something worse.
U.K.-based surgeon Dr. Karan Rajan explained the pink slime phenomenon in a TikTok video that’s received over 640,000 views. “You've seen this pink slime lurking in your bathroom, it's not mold, it's bacteria,” Dr. Rajan says. “Specifically one called Serratia marcescens. And it vomits hot pink all over your bathroom.”
Yes, that’s not soap that has turned a bubble-gum color on the bottom of your shower curtain or Pepto Bismol that didn’t go down the drain. It’s bacteria vomit.

The interesting thing about this bacteria is that the products you use to clean your body in the shower or wash your hands in the sink are what it loves to eat. Pink slime feeds on fat and mineral deposits from soap scum and shampoo.
If you’ve found some pink slime in your home before, you know it’s much grosser than you originally thought. But is it dangerous? “[To] the average person, it's pretty harmless, even if you come into contact with it, but you still wanna avoid getting in your eyes or open wounds,” Dr. Raja warns. “However, it can cause gut, urine, or chest infections in those who are immunocompromised.”
"OMG this reappears in our tub every few weeks. I was wondering what it was!?" someone wrote in the comments on the TikTok post. "I always wondered. The pink slime and my bleach bottle are in a constant battle," another added.
The bigger problem of pink slime is that it may be a symptom of a more significant issue. “If your home has enough damp for pink slime to consistently develop, you could actually be growing other things as well, like actual household molds, which could be causing respiratory issues or allergies,” Dr. Rajan says.

How to prevent pink slime from growing in your bathroom
How do you keep pink slime from growing in your home in the first place? The key is to keep your bathroom dry. “The first rule of Pink Slime Club is to keep the bacteria forming in the first place. By curbing its growth, you'll be preventing other dangerous molds from forming,” Dr. Rajan says. “Keep your shower dry and well-ventilated, put on an exhaust fan or open a window after showering to keep humidity levels low, and regularly clean and disinfect your bathroom. It's filthier than you think.”
