Bacteria found in Internet breast milk

CHICAGO — Human breast milk is sold for babies on several online sites for a few dollars an ounce, but a new study says buyer beware: Testing showed it can contain potentially dangerous bacteria including salmonella.

The warning comes from researchers who bought and tested 101 breast milk samples sold by women on one popular site. Three-fourths of the samples contained high amounts of bacteria that could potentially sicken babies, the researchers found. They did not identify the website.

The results are “pretty scary,” said Dr. Kenneth Boyer, pediatrics chief at Rush University Medical Center in Chicago, who was not involved in the study. “Just imagine if the donor happens to be a drug user. You don’t know.”

The research cites several cases of infants getting sick from strangers’ milk published in medical literature.

Breast milk is also provided through milk banks, whose clients include hospitals. They also charge fees but screen donors and pasteurize donated milk to kill any germs.

With Internet sites, “you have very few ways to know for sure what you are getting is really breast milk and that it’s safe to feed your baby,” said Sarah Keim, the lead author and a researcher at Nationwide Children’s Hospital in Columbus, Ohio. “Because the consequences can be serious, it is not a good idea to obtain breast milk in this way.”

The advice echoes a 2010 recommendation from the federal Food and Drug Administration.

“When human milk is obtained directly from individuals or through the Internet, the donor is unlikely to have been adequately screened for infectious disease or contamination risk,” the FDA says. “In addition, it is not likely that the human milk has been collected, processed, tested or stored in a way that reduces possible safety risks to the baby.”

The researchers believe theirs is the first study to test the safety of Internet-sold milk, although several others have documented bacteria in mothers’ own milk or in milk bank donations. Some bacteria may not be harmful, but salmonella is among germs that could pose a threat to infants, Boyer said.
