Sterilization of water

Water used in the feeding of infants, in the preparation of infant formulas or other infant foods, or for drinking, must be safe (i.e. clean and free of microbiological and chemical contamination). To ensure pathogen-free water for infants under 4 months of age, it is recommended that water be brought to a rolling boil for at least 2 minutes.

Storage of sterilized water

Boiled water can be stored for 2 or 3 days in the refrigerator in a sterilized, tightly closed container, or for 24 hours at room temperature in a sterile closed container.

Types of water

Tap water, well water that meets standards of safety and commercially bottled water (except carbonated or mineral water) are generally suitable for infant feeding. All three types of water, including commercially bottled water, are not sterile.

Commercially bottled non-carbonated water

All bottled waters legally sold in Canada are required to meet safety requirements set out under Canada's Food and Drugs Act and Regulations. The only commercially bottled non-carbonated waters suitable for use by infants are natural spring water drawn from underground springs, and treated water (low mineral content). Examples of commercial water unsuitable for infant feeding include mineral water, treated water with a high mineral content and carbonated water, including club soda. There are commercially bottled waters specifically for infants and these are labelled as such.
