A doctor has a stark warning: that ‘pink slime’ in your bathroom isn’t just an eyesore—it’s a sneaky bacteria called serratia marcescens.

Dr. Karan Raj took to TikTok with a reality check: “If you’ve seen this pink slime lurking in your bathroom, it’s not mould – it’s bacteria.” This uninvited guest loves damp spaces, feasting on soap and shampoo residue. Infectious Disease Advisor adds, “It may be found in the corner of wet showers or wash basins, where it is visible due to the red-colored pigment (prodigiosin) it produces.”

While mostly harmless, Dr. Karan warns: “You still want to avoid getting it in your eyes or open wounds.” For those in hospitals or with weakened immune systems, it’s a bigger threat—being “often resistant to multiple antibiotics, which can make it difficult to treat.”

So, how do you fight back? Dr. Karan’s advice: “Keep the bacteria from forming in the first place.” Keep your bathroom fresh with ventilation, use an exhaust fan or open a window, and scrub surfaces regularly with disinfectant. A clean bathroom means a healthier home!
