Warning Over Breast Milk Sold Online

They want to do it, but many new mothers simply cannot breastfeed.

Some have trouble expressing breast milk, while others struggle to get the baby to latch on or have pain when they do. With the best of intentions, some moms resort to buying breast milk online, which, it turns out, can pose risks.

A study published today in the journal Pediatrics compared 100 samples of breast milk bought online with breast milk from a community “milk bank” where moms donate excess milk. The Internet breast milk contained more bacteria, including strains of staphylococcus and streptococcus. Twenty-one percent of the Internet-sourced samples even included cytomegalovirus, or CMV, a virus that can cause serious neurological effects, compared with 5 percent of the milk bank samples.

None of the samples studied tested positive for HIV.

Study author Sarah Keim, assistant professor of pediatrics at Ohio State University College of Medicine, said information about the risks and the quality of breast milk bought on the Internet has been limited until now.

“There is no real data,” she said. “Just a small study in several countries about why women shared their breast milk.”

Other experts agree that purchasing breast milk over the Internet can be very risky.
