Unlike the breast milk from special donor banks, the milk for online sale does not have to be checked for viruses or diseases, the report, released Wednesday, stated. This makes the substance cheaper and provides faster access to it, making it more appealing to customers, most of whom are mothers unable to breastfeed.
"At present milk bought online is a far from ideal alternative, exposing infants and other consumers to microbiological and chemical agents," the report said.
The biggest threat is from viruses such as hepatitis B and C, HIV, and syphilis, as they are incurable or require serious treatment that an infant's body finds very difficult to cope with.
There are 17 milk banks registered in Britain, according to the United Kingdom Association for Milk Banking (UKAMB). Commonly, the banks collect breast milk from pre-screened, healthy new mothers, who have a plentiful milk supply.
