Sorry I deleted my post before noting who wrote it, but to the person who uses the formula for surgery. If you go to the nursery and look on the flats of formula and products from Ross you will only see the word sterile listed on the bottles of sterile water. Why do they feel that they *only* need to make sure it says sterile on the water bottles if the formula is supposedly sterile also? I don't know about the Mead formula as we don't carry that at our hospital. Claudia Globerger Gurnee, IL
