It’s commonly found in damp corners of showers, bathtubs, and sinks, particularly where moisture and soap scum build up. While the bacteria is generally harmless for healthy individuals, it can pose health risks for people with weakened immune systems or open wounds.
“In most cases, it’s not dangerous,” Dr. Karan said. “But you want to avoid getting it in your eyes or into cuts, especially if you’re immunocompromised.”
According to Infectious Disease Advisor, Serratia marcescens can cause urinary tract infections, respiratory issues, and other complications in vulnerable individuals, and it’s often resistant to multiple antibiotics, making it difficult to treat in medical settings.
The presence of pink slime may also be a sign of poor ventilation and excess moisture, which can contribute to the growth of other, potentially more harmful moulds. “If your home has enough dampness for pink slime to consistently develop, you could also be growing actual household mould, which may lead to respiratory issues or allergies,” Dr. Karan added.
To reduce the risk, Dr. Karan recommends keeping bathrooms well-ventilated. “The first rule of Pink Slime Club is prevention. Keep your shower area dry and ventilated,” he advised. This can include using an exhaust fan, cracking open a window during and after showers, and regularly disinfecting surfaces.
Routine cleaning with antibacterial products, particularly in areas where water pools or soap residue builds up, is also essential. “It’s not just about appearance, it’s about keeping your space safe and healthy,” Dr. Karan concluded.
