A viral wellness trend is drawing attention to an unsafe comparison: whether raw animal milk is essentially the same as human breast milk because neither is necessarily pasteurized before an infant consumes it.
Experts say that comparison misses several important differences between the two. Human breast milk is biologically designed for human infants, while raw milk from animals can carry harmful pathogens and does not provide the nutritional profile babies need.
Major medical organizations, including the American Academy of Pediatrics, the Centers for Disease Control and Prevention, the Food and Drug Administration and the American Medical Association, do not recommend raw milk consumption because of the risk of foodborne illness.
Here are five important facts parents should know.
Breast milk and raw animal milk are fundamentally different
Human milk is specifically adapted to the nutritional and developmental needs of human babies. Cow’s milk and other animal milks are designed for their respective species and have substantially different amounts of protein, minerals, fats and other nutrients.
Human milk also contains a complex combination of immune factors, hormones, enzymes and other bioactive components that support infant development.
Raw cow’s milk does not replicate those properties. It is therefore not an alternative to breast milk or infant formula for babies.
The way milk is collected matters
Another major difference involves contamination risk.
Human milk is generally expressed directly from the breast or collected using a clean breast pump. Animal milk is collected from animals and can become contaminated with bacteria or other pathogens during milking, handling, storage or transportation.
Pasteurization is designed to reduce those risks by heating milk to a specific temperature for a set period. Removing that safety step can leave consumers exposed to organisms capable of causing serious illness.
Donated human milk supplied through established milk banks is also treated differently from raw animal milk. Milk banks screen donors and pasteurize donated milk to reduce potential contamination risks, particularly for medically vulnerable infants.
Babies should not receive raw milk
The risks are especially concerning for infants and young children.
Children younger than 12 months should not be given cow’s milk as a primary drink. Recommended feeding options include breast milk, infant formula or appropriately screened and processed donor human milk.
Cow’s milk does not contain the right balance of nutrients for an infant. It contains insufficient amounts of certain nutrients, including iron and vitamin E, while providing excessive amounts of protein and some minerals for a baby’s needs.
Adding the potential bacterial contamination associated with unpasteurized milk creates another avoidable health risk.
Raw milk can cause serious infections
Unpasteurized milk can contain pathogens including Salmonella, Campylobacter, Listeria, Brucella and certain strains of E. coli. Children can be particularly vulnerable to complications from these infections.
Young children have developing immune systems and can become severely dehydrated when illness causes significant vomiting or diarrhea. Some foodborne infections can also progress to invasive disease and other serious complications.
Raw milk outbreaks have repeatedly demonstrated the potential danger. Children and teenagers have represented a substantial share of cases in some documented outbreaks, reinforcing why health authorities recommend avoiding unpasteurized milk.
Breastfeeding parents should avoid raw milk, too
The safety concern does not disappear simply because an adult is breastfeeding rather than giving raw milk directly to a baby.
A breastfeeding parent who becomes seriously ill after consuming contaminated milk may have difficulty caring for their infant or maintaining normal feeding routines. Certain infections can also create additional concerns involving close contact between a sick parent and a vulnerable baby.
For breastfeeding parents, avoiding raw milk is therefore a straightforward way to reduce an unnecessary source of foodborne illness.
Why pasteurization still matters
The argument that breast milk is consumed without pasteurization overlooks the fact that human milk and raw animal milk are biologically and nutritionally different products.
Breast milk has evolved to meet the needs of human infants. Raw animal milk, meanwhile, can contain harmful microorganisms without providing the nutritional composition required by babies.
For parents, the takeaway is simple: Breast milk and raw milk are not interchangeable. Babies should receive breast milk, infant formula or appropriately processed donor milk, while children and breastfeeding parents should avoid the unnecessary risks associated with unpasteurized animal milk.
A viral wellness claim may sound logical when reduced to a simple comparison, but the science behind the two types of milk is far more complicated. When it comes to feeding babies and protecting young children from preventable infections, established safety guidance remains the better choice.
