It is a quiet, sterile room in Columbus, Ohio. You might expect it to smell like a hospital, but it mostly smells like nothing at all—clean, cold, and efficient. This is the heart of the OhioHealth Mothers Milk Bank, a place that feels a bit like a high-tech laboratory crossed with a community center. While most people think of blood banks when they hear about medical donations, milk banks are arguably just as critical, especially if you’re a three-pound infant fighting for your life in a Neonatal Intensive Care Unit (NICU).
Milk is medicine. That isn't just a catchy slogan used by lactation consultants; it is a clinical reality.
For a premature baby, human milk is a shield. It reduces the risk of Necrotizing Enterocolitis (NEC), a devastating intestinal disease that can be fatal for preemies. When a mother’s own milk isn't available—maybe because of medical complications, stress, or delayed supply—donor milk from the OhioHealth Mothers Milk Bank becomes the gold standard for care. It is basically the difference between a baby thriving and a baby struggling to survive their first month of life.
Why Donor Milk is a Medical Necessity
We need to talk about what's actually in this stuff. It’s not just "food." Human milk contains bioactive components, stem cells, and antibodies that formula simply cannot replicate. Formula is a miracle of modern science, don't get me wrong, but for a micro-preemie with an underdeveloped gut, it can be hard to process.
The OhioHealth Mothers Milk Bank is one of the oldest and most respected facilities in the country. They are a charter member of the Human Milk Banking Association of North America (HMANA). This is kind of a big deal because HMANA sets the rigorous safety standards that ensure every drop of milk is safe for the most vulnerable patients.
Honestly, the process is intense.
It starts with the donors. These are women who have an oversupply of milk and decide to go through a massive amount of paperwork and blood testing just to help a stranger's baby. They aren't paid. This is a purely altruistic act. They undergo a screening process that’s remarkably similar to donating blood: a health history review, a physician’s sign-off, and blood tests to screen for HIV, HTLV, Hepatitis B and C, and Syphilis.
The Science of Safety
Once the milk arrives at the facility—often shipped in coolers packed with dry ice—it doesn't just go into a bottle.

First, the staff tests it. They look for bacteria. Then, they mix it. This "pooling" process is actually quite smart because it balances out the nutritional content. One mom might have milk that is higher in fat, while another has milk higher in specific proteins. By pooling milk from several donors, the bank ensures a consistent, high-calorie product.
Then comes the pasteurization. They use the Holder Method. This involves heating the milk to 62.5 degrees Celsius for 30 minutes. It’s a delicate balance. You have to kill the pathogens—the bad stuff—without destroying the precious immunological properties that make human milk so special.
After pasteurization, the milk is frozen and stored. It can stay frozen for up to a year, though it usually flies out the door much faster than that. Hospitals across Ohio and even in neighboring states rely on these shipments to keep their NICUs running.
The Logistics of Giving
People often ask if they can just drop off a bag of milk they found in the back of their freezer. The short answer? No.
The OhioHealth Mothers Milk Bank has very specific rules. If you've taken certain medications or if you've had a beer within a specific window, that milk might not be eligible for donation. They are incredibly picky, and they have to be. We’re talking about babies whose immune systems are basically nonexistent.
If you want to become a donor, you start with a phone screening. It’s a chat with a real human being who walks you through your health history. If you pass that, you get a packet of forms. You’ll need your OB/GYN and your baby’s pediatrician to sign off on it. OhioHealth even pays for the blood work. They try to make it as easy as possible, but the safety bar remains sky-high.
Where the Milk Goes
Most of this milk is destined for hospitals. It's prescribed by doctors.

However, sometimes there is a surplus. When that happens, the milk bank can provide milk to outpatient families. This is usually for babies with specific medical needs—maybe they have a severe protein allergy or a failure to thrive. It’s not cheap, though. There is a processing fee to cover the costs of the testing, the pasteurization, and the shipping. The milk bank is a non-profit, but the electricity for those industrial freezers and the salaries for the lab techs have to come from somewhere.
Many insurance companies are starting to cover the cost of donor milk, but it’s still a bit of a battle. Advocates are constantly working to pass legislation that requires Medicaid and private insurers to pay for donor milk when it’s medically necessary.
Common Misconceptions About Milk Banking
A lot of folks get confused between a regulated milk bank like OhioHealth and "informal milk sharing."
You've probably seen it on Facebook groups—moms offering extra milk to neighbors. While the intent is beautiful, the risk is real. Informal sharing doesn't involve blood testing or pasteurization. You don't know if the milk was stored at the right temperature or if the containers were sterilized.
The OhioHealth Mothers Milk Bank eliminates that guesswork.
Another weird myth is that donor milk is "watered down." Absolutely not. In fact, it’s tested for caloric density. If the milk doesn't meet a certain caloric threshold, it might not be used for the tiniest babies who need high-energy fuel to grow.

When a baby in the NICU gets donor milk instead of formula, their risk of NEC drops significantly. NEC is incredibly expensive to treat. It often requires surgery and long hospital stays. By investing in donor milk upfront, hospitals actually save thousands—sometimes hundreds of thousands—of dollars in long-term care costs.
More importantly, it saves lives.
The OhioHealth Mothers Milk Bank isn't just a local resource; it’s a hub of research. They collaborate with scientists to better understand how human milk influences the microbiome. They are looking at how different pasteurization methods might preserve more of the milk’s living cells.
How to Support the Mission
Maybe you aren't a lactating mother with extra milk. You can still help.
The milk bank survives on donations—both milk and monetary. They use funds to subsidize the cost of milk for families who can't afford the processing fees. They also use it to buy new equipment.
If you are a mom with a "stash" and you're thinking about donating, don't wait. The younger the milk is, the better. Milk pumped in the first few months postpartum is particularly rich in the nutrients these NICU babies need.
Actionable Steps for Potential Donors and Supporters:
- Check the basic requirements: You generally need to be in good health, a non-smoker, and taking minimal medications. Even some vitamins are okay, but you’ll need to disclose everything.
- Contact the bank directly: Call the OhioHealth Mothers Milk Bank at 614-566-0630. They are very friendly and will walk you through the initial screening in about 15 minutes.
- Organize your freezer: If you’re approved, you’ll need to label your milk with the dates it was pumped. The bank provides specific bags or containers in some cases.
- Drop-off or Ship: OhioHealth has numerous "milk drop" sites throughout Ohio and surrounding areas. These are often located in hospitals or lactation centers. If you aren't near a drop site, they can arrange for shipping.
- Spread the word: Many moms don't even know this exists. If you see someone on social media complaining about an overflowing freezer, tell them about the milk bank. They could be sitting on a literal lifesaver.
- Advocate for coverage: Contact your local representatives to support bills that expand insurance coverage for donor human milk.
The work being done in that cold, quiet room in Columbus ripples out across the entire region. Every bottle of pasteurized milk represents a mother’s generosity and a baby’s best chance at a healthy future. It is a community coming together to protect its smallest members, one ounce at a time.
