Rachel Holtzman pours donated breast milk from a network of women into a bottle for her son in New York, Oct. 20, 2013. A report found that breast milk bought from two popular websites was often contaminated with high levels of bacteria, including salmonella. �We�ve had the milk of about 30 women and have never had a problem,� she said.

Study finds salmonella, other risky bacteria in breast milk sold online

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 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 published in medical literature of infants getting sick from strangers’ milk.
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 … 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.
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. Sources for bacteria found in the study aren’t known but could include donors’ skin, breast pumps used to extract milk, or contamination from improper shipping methods, Keim said.
The study was published online Monday in the journal Pediatrics.
There are many milk-sharing sites online, including several that provide milk for free.
Keim said it’s unclear whether milk from sites offering donated milk would have the same risks because donors might be different from those seeking money for their milk. And in a comparison, the researchers found more bacteria in breast milk purchased online than in 20 unpasteurized samples donated to a milk bank.
