A recent study of breast milk bought online shows a prevalence of cow’s milk in their samples. The researchers bought about 102 samples of milk through various online sites. Then, they tested for cow DNA in the samples and found that more than ten percent of the samples contained cow’s milk. Some of the samples contained a significant amount of cow’s milk of at least ten percent or more, ruling out accidental contamination.
The United States has a network of nonprofit milk banks throughout the country. They screen the donors and pasteurize the milk. The problem for many women is that they charge more than the online milk exchanges because of low supplies. Premature babies in hospitals are given priority access to milk from the banks. Women who are, or expect to be, lactating in the near future should register to donate their excess milk to these banks to help supply more milk to more mothers.
