Worried about Serratia Marcescens or allergies?

Patient: Hi hi! i am worried because everytime i clean my shower after just a few days there is a buildup of a pink film in some places in the shower or around the toilet, i think it is serratia marcescens? i am worried that it can harm me and my family i have a 6 month old baby, also i recently have been having trouble breathing so i was worried maybe that pink mold was causing it, but i think that it may be just from allergies, anyways should i be worried about the serratia marcescens?

Symptoms: Trouble breathhing thorugh nose
