Caution

You must have heard scary stories about infants dying of the Cronobater virus. This virus basically inhabits baby formulas. This virus can be fatal to an infant’s life, so you need to be very careful with properly storing the formula, whether prepared or unprepared.

Powdered Formula

Now, moving on to the consistency of the formula. In the case of a powdered formula can, you can store it for about a month once opened but not more than that. An unopened can of powdered baby formula can be stored for as long as the expiry date allows. This is the reason why you shouldn’t get bigger cans of baby formula. The recommended size is a 24 oz can.

Concentrated Liquid Formula

A concentrated liquid formula, once opened, can last for about forty-eight hours with good refrigeration. You must be very careful with storing the formula, especially in humid areas. In this case, you are again recommended to buy a smaller can which you are hundred percent sure to use in the next forty-eight hours.

Prepared Formula

Once you prepare the formula, things get more critical. Now, you can only store the bottle of prepared formula for twenty-four hours, and that too with excellent refrigeration. If you leave the bottle of prepared formula unattended, you will notice the formula getting spoiled within an hour. This spoiled formula can have an adverse effect on your baby’s life, so always be careful with properly storing it.
