I know this has been hashed out a lot here, I was hoping someone may have a good link bookmarked.
(Lurkers, visit milkshare via Yahoo groups and DONATE you milk to needy mamas and babies! Breast milk is a birthright, not a commodity!)
Of course breastmilk is a body fluid but it doesn't require special precautions according to CDC. If the CDC were to issue warnings about breastmilk being a hazardous body fluid it would be easier to make laws prohibiting selling or sharing breastmilk.
"CDC does not list human breast milk as a body fluid for which most healthcare personnel should use special handling precautions. Occupational exposure to human breast milk has not been shown to lead to transmission of HIV or HBV infection."
Here is a link to a good article called Liquid Gold
I read the California breastfeeding laws and I didn't see anything that said it was against the law for an individual to sell her milk. I could be wrong or I may not have found the most recent laws. My laptop isn't functioning well. What is says is that milk bank and hospital employees aren't selling milk by doing their job. You can find California laws by doing a Google search.
From what I have read it will be difficult to prohibit the sale of milk by calling it a hazardous fluid. There have been no cases of babies becoming ill from milk sharing. How they may be able to prohibit the practice is by calling human milk a food and regulate selling human milk as a food product. Interesting.
