How Hospitals Use Donor Human Milk from the Rogers Hixon Ontario Human Milk Bank

Hospitals use donor human milk from the Rogers Hixon Ontario Human Milk Bank as a prescribed, pasteurized feeding option for hospitalized infants whose mothers' own milk is not available in sufficient quantity. The milk is supplied to hospitals rather than sold directly to families, and it is prioritized for the most vulnerable babies — particularly preterm and low-birth-weight infants. According to the milk bank, 52 hospitals across Ontario and the Atlantic provinces currently benefit from its donor milk, and more than 1,500 low-birth-weight infants in Ontario could benefit each year.

Which infants typically receive donor milk

The milk bank describes its purpose as supplying "high-quality pasteurized donor human milk to hospitalized infants across Ontario who need it most." In practice, that means the smallest and sickest patients:

• Preterm infants — babies born early, whose mothers may not yet be producing enough milk or who are too immature to feed directly at the breast.
• Low-birth-weight infants — the milk bank cites 1,500+ low-birth-weight infants in Ontario who could benefit annually.
• Hospitalized infants with medical need — including babies with conditions that make feeding challenging. One donor story on the site describes a son born at 27 weeks, and another describes a baby with congenital heart disease (CHD) whose mother pumped and later donated.

Donor milk is used when a mother's own milk is unavailable or insufficient — it supplements or substitutes for the mother's milk during a hospital stay, not as a routine alternative when maternal milk is available.

How many hospitals receive the milk

The milk bank reports that 52 hospitals across Ontario and the Atlantic provinces currently benefit from its donor milk. This reach matters because it means a hospital does not need its own milk-processing capability to offer pasteurized donor milk — it can be supplied through the milk bank network. If you are trying to find out whether a specific hospital uses donor milk, the milk bank's "Using donor human milk" section is the intended starting point for hospitals and clinicians.

Why pasteurized donor milk matters

Pasteurization is the step that makes pooled donor milk safe to give to vulnerable infants. The milk bank states its team can pasteurize 300 litres of donor human milk in a single week, and that it has published 50+ research papers aimed at "making donor human milk safer through research and care."

The core mechanism: donor milk is screened, pooled, and heat-treated to reduce the risk of transmitting infectious agents, then provided to hospitals for infants who cannot get enough of their own mother's milk. For a preterm or low-birth-weight baby, having a human-milk-based feeding option matters because it is closer to the biological norm than formula alternatives — which is why the milk bank frames its work as giving "Ontario's vulnerable preterm infants a stronger start."

How hospitals learn about using donated human milk

The milk bank provides a dedicated pathway for hospitals rather than a self-serve ordering system. Its site lists a "Using donor human milk" section described as: "Discover how and why donor milk is important for hospitals." That is the entry point for hospital staff to understand eligibility, handling, and how supply works.

On the donation side — relevant because hospital supply depends on it — the milk bank reports that 8,500+ prospective milk donors have been screened since 2013. Donors are screened before their milk enters the supply chain, which is part of what allows hospitals to treat donor milk as a controlled medical product rather than an informal exchange.

What this means if you are a parent or clinician

• If you are a parent of a hospitalized infant: donor milk is typically offered through the hospital's clinical team when your own milk is not available in sufficient quantity. Ask your care team whether donor milk is used at your hospital and under what criteria.
• If you are a clinician or hospital administrator: the milk bank's "Using donor human milk" resources are the place to start, and the 52-hospital figure indicates an established distribution network across Ontario and the Atlantic provinces.
• If you are considering donating: donor milk only reaches hospitals because of screened donors. The milk bank's "Learn how to donate" pathway covers the process, and its donor stories (Adhiyat, Alina, Meghal) illustrate the range of reasons people donate — from oversupply to gratitude for donor milk that helped their own child.

The throughline is that donor milk is a hospital-supplied, pasteurized, screened resource directed at the infants with the greatest need, not a general consumer product.
