New research shows that a portion online breast milk contains cow DNA.
The study — published in the journal Pediatrics — examined 102 samples of breast milk acquired on the Internet. About 10% of these contained cow milk.
All samples did contain human DNA but some contained a substantial amount of cow DNA. “One of our samples was almost half and half [cow-milk-based baby] formula and milk,” said epidemiologist Sarah Keim, who led the study.
She added that the research backs up warnings by the Food and Drug Administration and the American Academy of Pediatrics regarding the risks of purchasing online breast milk.
About 55,000 people a year buy breast milk over the web.
