In a message dated 97-09-11 18:16:09 EDT, you write: << Anyway, Lois (or whoever it was) told me the smell was from the breaking down of certain fatty acids that occurred in some mother's milk when stored. She said it was perfectly safe for my baby, my husband was satisfied, and she recieved this milk every other weekend for many months. >> While the (fresh, properly stored) milk isn't dangerous -- the "spoiled" smell isn't caused by bacterial action, but an enzyme which breaks down the fats -- some women find that their milk can quickly become so foul tasting/smelling that a baby will refuse to drink it. Since the levels of lipase in milk can vary, the effect on the milk can range from a mild sourness to a really nasty taste and odor. All that I meant in the previous post is that the action of the lipase in the milk can't be reversed -- sorry if I didn't make it as clear as I wanted to. Diane DiCarlo LLLL Brooklyn, NY
