Human milk donated to a milk bank can become contaminated in a number of ways, but processes exist to eradicate pathogenic bacterial growth. Donor human milk may be cultured before or after pasteurization or both. The purpose of this article is to describe standard operations of the Mothers' Milk Bank of the Children's Hospital of Philadelphia, best practices to limit the bacterial contamination of donor human milk, and implications for future research.
