Pink stains on shower seals are usually caused by Serratia marcescens, an airborne bacteria that feeds on soap scum, or a reaction between shampoo ingredients and the rubber. You can remove them easily by scrubbing with a baking soda paste and disinfecting the seals with a diluted bleach or hydrogen peroxide solution.

Repeat as necessary.
The bacteria will grow in any moist location where phosphorous containing materials or fatty substances accumulate. Sources of these substances include soap residues in bathing areas, feces in toilets, and soap and food residues in pet water dishes.
As long as it doesn't enter the body, contact with Serratia marcescens during washing or cleaning is generally safe for healthy people (be careful not to touch the eyes or open cuts with contaminated hands).
Pink mold isn't actually a mold; it is a pigmented bacteria (usually Serratia marcescens). While not as toxic as black mold, it can be dangerous to individuals with weakened immune systems, and it poses risks if it enters open wounds, the urinary tract, or the eyes.
Serratia marcescens is generally harmless to healthy individuals but can be highly dangerous to those with weakened immune systems or underlying health conditions. It is a frequent cause of severe hospital-acquired infections, such as pneumonia, urinary tract infections, and bloodstream infections, which can be difficult to treat due to high antibiotic resistance.

Symptoms are often subtle and mimic other illnesses, but common red flags include persistent allergy-like reactions, chronic fatigue, unexplained brain fog, recurring headaches, and respiratory or digestive distress.
Pink mold isn't technically a mold but rather a type of bacteria known as Serratia marcescens. While it's not as dangerous as black mold, it's still worth cleaning up as it can lead to minor infections, particularly in people with weakened immune systems.
Yes, vinegar kills pink mold. Since "pink mold" is actually a pigmented airborne bacteria (usually Serratia marcescens), vinegar's acetic acid easily breaks down its slimy film.
The main risk factors for bacteraemia/sepsis which is caused by Serratia is hospitalization, placement of intravenous catheters, intraperitoneal catheters and urinary catheters and prior instrumentation of the respiratory tract [2–5]. Serratia marcescens causes both opportunistic and nosocomial infections.
Although the bacterium prefers moist environments (e.g. washbasins, taps, drains, liquid soap dispensers, air-conditioning systems or nebulizers), it can survive up to 2 months on dry surfaces [5,12,13], up to 20 days in anaerobic conditions or in conditions with low oxygen levels [14] and contaminate surface ...
MRSA (Methicillin-resistant Staphylococcus aureus) typically begins as a skin infection. The earliest warning signs include swollen, red, or painful bumps that resemble a pimple, boil, or spider bite. The affected area may feel warm to the touch and begin leaking pus or fluid.
