A Case Report of Pink Breast Milk

A woman presented for her postpartum examination alarmed about pink stains on her breast pads and on her infant's burp pads and diapers. The stains were also found in her breast pump and the infant's bottles. Out of concern, she stopped breastfeeding. The diagnosis was colonization of mother and infant with Serratia marcescens. They were managed conservatively without antibiotics. The mother was guided to restart breastfeeding. The infant resumed nursing and continued to thrive.
