Is breast milk sterile

191 19.07.2019
The effect of storage on the microbiological content, lipid composition, cellular components, anti-bacterial properties and antioxidant capacity has been investigated extensively; however, many factors still remain unknown. Along with changes occurring over time, different problems arise from storing breast milk at various temperatures, including room, refrigeration and freezing temperatures. This means separate recommendations are required for different temperatures and storage situations. Breast milk retains most of its immunological properties in glass or hard plastic containers that do not contain polyethylene. In addition, containers made with Bisphenol A BPA are no longer used for baby bottles because of its adverse effects. As there may be some concerns about glass breaking, ideal containers for milk storage are therefore food-grade hard plastic, made without BPA, with leak-proof lids.

Pumping Breast Milk Changes Its Microbiome

By Karen Robock Aug 19, New bottles and nipples should be sterilized on first use. Place sterilized bottles and pump kit parts on a piece of paper towel to air-dry instead of a dishtowel, which could contain traces of bacteria. Have more bottle-feeding questions?

Storing and thawing breast milk

Until relatively recently, most researchers thought that breast milk was sterile. The composition of its microbiome varies based on a number of factors—including whether the milk was pumped, or fed to an infant directly from the breast, according to a study published today in the journal Cell. The differences contribute to our understanding of pumped milk, which has usually been grouped in with breastfeeding. The research team examined the breast milk microbiome from just under mother-infant pairs participating in the Canadian Healthy Infant Longitudinal Development CHILD study, which is tracking participants from pregnancy through childhood and adolescence. The results showed that the milk was highly variable, and different women had different types and amounts of bacteria in their milk.
