Essential features of artificial infant formula:
(1) bacteriologically sterile
(2) consistency similar to breast milk, with ratio of water to solids of 87:13 (6.7:1).
(3) caloric content similar to breast milk (620-700 kcal per liter)
(4) content of each nutrient similar to that of breast milk
(5) free of substances or additives not normally present in breast milk
(6) essential nutrients should be at levels sufficient to meet the infant's daily physiologic requirements
(7) free of toxic contaminants (pesticides, toxins, heavy metals, radioactive materials)
where:
• The formula should be bacteriologically sterile when it is fed to the infant. I am not sure if this is essential for dry or concentrated formula prior to preparation. It definitely should not contain pathogenic bacteria or large numbers of other bacteria.
