Women who can't breast-feed are turning to the internet and getting breast milk from mothers who have a surplus, but the government is warning new moms that breast milk sharing may not be such a good idea.

In November, the Food and Drug Administration issued a warning against feeding babies breast milk acquired directly from individuals or through the internet saying that in such cases "the donor is unlikely to have been adequately screened for infectious disease or contamination risk" and that "it is not likely that the human milk has been collected, processed, tested or stored in a way that reduces possible safety risks to the baby."
