A small but growing market exists on the internet for human breast milk.
Now a study finds that buyers should really beware—some purveyors of breast milk appear to be adulterating their product with cow's milk.
Such bovine contamination is more than just a scam:
it can be a health risk for infants who are allergic 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 ten of these samples had enough bovine DNA to indicate that at least 10% of the milk in the sample actually came from cows.
Human milk is an ideal source of nutrients for infants—when it's safe.
Prior studies on breast milk purchased online have revealed dangerous amounts of bacterial growth that make it unsuitable for infant consumption.
Since no one typically screens these internet-sold milk products for pathogens or other contamination 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.
参考译文
目前网络上对于母乳感兴趣的买家们规模虽小但正日渐壮大。
现在一项研究发现买家们需要提高警惕—因为一些母乳供应商似乎在自己的商品中掺杂了牛乳。
这种掺假行为不仅是对消费者的欺骗：
而且对一些牛奶过敏或患乳糖不耐症的婴儿来说会造成健康隐患。
首先报道这一牛奶骗局的是在《儿科》杂志发表的一项研究。
研究人员在网络上购买了102份母乳样本。
检验结果显示这些样品中含有足量牛科动物基因，表明其中至少有10%的母乳其实是牛奶。
唯有安全性得到保障，母乳才是婴儿理想的食物。
早先对母乳的研究表明，网上购买的相关产品会有婴儿不适的危险细菌。
由于这些网络上的母乳是否含有病原体或其他细菌没有特别的检验程序，消费者们想保护自己只能听天由命。
当然一些母乳银行机构确实会对其产品进行检验。
因此消费者最好还是前往当地卫生部门进行检测确保买到安全的产品。
