At Birmingham Women’s Hospital in England, a local charity bike service called Midlands Freewheelers has switched from delivering blood to delivering breast milk. The hospital used to rely on mothers bringing donated breast milk to the hospital but found that new mothers were too busy. So the Midlands Freewheelers go directly to the mothers, who are screened for HIV, hepatitis B and hepatitis C, and they must be nonsmokers. After the milk arrives at the hospital, it’s put into small bottles, pasteurized and frozen. The Midlands Freewheelers has been so successful that it is looking to expand to other hospitals.
