MIAMI (AFP): One in 10 samples of breast milk sold on the Internet in the United States was found to be contaminated with cow’s milk or formula, US researchers have said. The study in the journal Pediatrics raised new safety concerns about a practice that many experts already discourage over the potential for danger to babies’ health. Researchers tested 102 samples of breast milk advertised on milk-sharing websites, frequented by mothers who want to buy breast milk for their infants.

 They found that 11 of the samples contained bovine DNA, and 10 of those had enough that it could not be considered an accidental contamination, suggesting that some sellers were adding cow’s milk in order to boost their volume and profits.
