If I wanted to get in touch with someone local to donate me milk which (apart from the usual health concerns) was also free of certain allergens ...where should I look to get the best match?
Dairy, eggs, nuts primarily.
Fish and gluten and soy would be an added bonus.
Can I make such a specialized request to the milkbanks though? And will they be able to provide me with such breastmilk? What about pathogens? Will it be free of them at that point (since I am assuming they do a thorough search and also pasteurize(or equivalent..is that true?))
Milk banks are regulated and must follow strict rules to ensure the safety of the milk. Milk is a bodily fluid and the exchange of such can transmit diseases. Here is some info from the bank in San Jose on testing and pasteurization. I have heard of banks that will supply you with milk from a woman following a specific diet, but I don't know if San Jose does this. You would just need to do some research on the different banks.
When I donated to a milk bank in 2006, I don't remember giving a lot of information about my diet. They did ask if I was on any medications or taking supplements. I also had to have blood tests done to test for HIV and hepatitis. I'm not sure if the diet questions have changed in the past few years.
I have seen a FB page where woman post if they have extra milk and offer it up free of charge. There was info on diet and how it was stored, which would be important if you were taking from a non milk bank donor. You might poke around looking for that. When I had a lot of extra milk, I didn't know anyone who needed it, so I contacted the milk bank.
I believe (don't quote me) that you need a prescription for a milk bank. I am not aware of a bank in WA.
I did come across this on FB. I cannot advocate anything about this site since I've never used it, but it could be something to look into.
