Given this risk and the paucity of case reports, recommendations range from expectant management to prophylactic antibiotics and cessation of breastfeeding. Here we present a literature review and a case of S. marcescens colonization obscured by symptoms in both the patient and her infant. A 30-year-old G8P4135 who was exclusively breastfeeding her 2-month-old infant contacted the Women\u2019s Health Clinic via her electronic medical record portal with a concern for contaminated breast milk after the milk left in a bottle overnight turned bright pink. Milk cultures from bilateral nipples showed colonization with S. marcescens. Following a literature review, decision was made to encourage continued breastfeeding and forego prophylactic antibiotics. She subsequently developed a febrile upper respiratory illness, and workup was negative for bacteremia with S. marcescens. Her colonization ultimately resolved spontaneously, and she continued breastfeeding without complication.Precis: Serratia marcescens is an uncommon colonizer of breast milk that does not require prophylactic antibiotics or cessation of breastfeeding in most cases.<\/jats:p>\n                  <jats:p>Precis:\u2002Serratia marcescens is an uncommon colonizer of breast milk that does not require prophylactic antibiotics or cessation of breastfeeding in most cases<\/jats:p>","DOI":"10.1093\/milmed\/usaf504","type":"journal-article","created":{"date-parts":[[2025,9,25]],"date-time":"2025-09-25T12:03:23Z","timestamp":1758801803000},"page":"e1749-e1751","source":"Crossref","is-referenced-by-count":0,"title":["LegenDAIRY Pink Breast Milk: A Case of Serratia Marcescens Colonization"],"prefix":"10.1093","volume":"191","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6190-6450","authenticated-orcid":false,"given":"Lt Michael J","family":"Goldstein","sequence":"first","affiliation":[{"name":"Gynecologic Surgery & Obstetrics Residency Program, Naval Medical Center Portsmouth , Portsmouth, VA 23708,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maj Bethany L","family":"Charron","sequence":"additional","affiliation":[{"name":"Gynecologic Surgery & Obstetrics Residency Program, Naval Medical Center Portsmouth , Portsmouth, VA 23708,","place":["United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,10,13]]},"reference":[{"key":"2026070413274813000_usaf504-B1","doi-asserted-by":"publisher","first-page":"150","DOI":"10.1016\/j.foodcont.2017.03.046","article-title":"Poor hygiene practices in infant formulae reconstitution, and inappropriate storage of feeding bottles can cause spoilage issues by Serratia marcescens","volume":"79","author":"Rachon","year":"2017","journal-title":"Food Control."},{"key":"2026070413274813000_usaf504-B2","doi-asserted-by":"publisher","first-page":"87","DOI":"10.1016\/j.jdcr.2023.10.027","article-title":"The case of the mysterious pink towels","volume":"43","author":"Huff","year":"2024","journal-title":"JAAD Case Rep."},{"key":"2026070413274813000_usaf504-B3","doi-asserted-by":"publisher","first-page":"347","DOI":"10.1093\/jpids\/pis102","article-title":"A pink milk bottle mystery","volume":"1","author":"Statler","year":"2012","journal-title":"J Pediatric Infect Dis Soc"},{"key":"2026070413274813000_usaf504-B4","doi-asserted-by":"publisher","first-page":"887","DOI":"10.1038\/nrmicro1531","article-title":"The biosynthesis and regulation of bacterial prodiginines","volume":"4","author":"Williamson","year":"2006","journal-title":"Nat Rev Microbiol"},{"key":"2026070413274813000_usaf504-B5","doi-asserted-by":"publisher","first-page":"e101","DOI":"10.1055\/s-0034-1387934","article-title":"Pink breast milk: Serratia marcescens colonization","volume":"4","author":"D, Valle","year":"2014","journal-title":"AJP Rep"},{"key":"2026070413274813000_usaf504-B6","doi-asserted-by":"publisher","first-page":"388","DOI":"10.1089\/bfm.2018.0002","article-title":"Serratia marcescens colonization causing pink breast milk and pink diapers: a case report and literature review","volume":"13","author":"Quinn","year":"2018","journal-title":"Breastfeeding Med"},{"key":"2026070413274813000_usaf504-B7","doi-asserted-by":"publisher","first-page":"257","DOI":"10.1016\/s0924-8579(99)00131-4","article-title":"Trendds in antimicrobial susceptibility of bacterial pathogens isolated from patients with bloodstream infections in the USA, Canada and latin america.
