In a message dated 97-06-20 08:33:30 EDT, you write: No one knows what temperature for how long it takes to kill HIV in human milk. Dear Mary, I have to disagree with you on this one. After teaching at the LC Training program, at the Georgetown University Hospital Lactation Center and Human Milkbank, I learned that the milk there was heat treated 10 degrees ABOVE100 % HIV kill as proved by cultures. This was in a word "overkill" just to be sure. The virus is very heat sensitive. This heat treating is something that can be done to milk that cannot be done to blood. So in that case blood and milk banking differ greatly. Lois Arnold, (HMBAMA e-mail-- [log in to unmask]) Vergie Hughes, and Mary Rose Tulley and other human milk bank directors, can all comment on this. Jane Bradshaw RN, BSN, IBCLC Lynchburg, VA
