 A small but growing market exists on the internet for human breast milk. Now a study finds that buyers should really be aware: some purveyors(供货商) of breast milk appeared to be adulterating(掺加) their product with cow’s milk.


  Such bovine 1(牛的) contamination is more than just scam(欺骗). It can be a health risk for infants who are allergic 2 to or intolerant of cow’s milk. The study, the first to document this milk fraud, is in the journal Pediatrics.
  Researchers purchased 102 samples of supposed human breast milk online. Tests found that 10 of these samples had enough bovine DNA 3 to indicate that at least 10% of the milk in the sample actually came from cows. 
  Human milk is an ideal source of nutrients 4 for infants, when it’s safe. Prior studies on breast milk purchased online have revealed dangerous amounts of bacteria growth that make it unsuitable for infant consumption. Since no one typically screens these internet sold milk products, for pathogens or other contaminations, it’s up to consumers to protect themselves. Some human milk banks do voluntarily screen their products, so it’s best to check with local departments of health to find safe products.
