    For parents who are new to formula feeding, there can be a bit of a learning curve when it comes to using infant formula safely. One of the natural curiosities that arises for parents is whether formula expires or not.

    Well, the short answer is yes. It absolutely does! But as with many aspects of formula feeding, there's more to the story than meets the eye. So, if you're unaware of the importance of the expiration date on formula or what happens if baby drinks spoiled formula milk, then this article is for you.

    Keep reading to uncover the differences between the baby formula expiration date and baby formula shelf life after opening. We also provide essential insights into what to do if baby drank old formula and symptoms to watch out for. Finally, we'll equip you with some creative ideas for using expired formula to help you minimize your waste.

    Formula Expiration Date: Why is it Important?

    formula expiration date

    The expiration date is important because if you use formula past this point, you're jeopardizing your baby's health. All infant formula containers are labelled with an expiration date, which tells consumers how long a sealed and safely stored container of formula is good until. 

    A common question we receive is: how long does formula last unopened? In most cases, baby formula's shelf life ranges between 18 months and 2 years, depending on the brand and type of formula. For example, powdered baby formula lasts longer than liquid formula.

    To find the expiration, look for the words "Use By" followed by a date. This is usually printed on the bottom of the box or can, typically next to the production batch number of the formula.

    To avoid confusion, it's important to note that the expiration date format will differ depending on whether you use an American or European formula.

    The standardized date format in Europe is DD/MM/YYYY, while expiration dates are commonly written as MM/DD/YYYY in the United States and Canada.

    It's critical to always check this date before feeding your baby. Beyond the expiration date, the nutrient content and quality of the formula cannot be guaranteed. Moreover, there could be harmful microbiological activity. Thus, it's essential to throw away expired baby formula and never feed it to your little one!

    How Long Does Baby Formula Powder Last Once Opened?

    When parents first begin formula feeding, many are unaware that the shelf life of baby formula after opening the container is shorter than the infant formula expiration date.

    That means once you've opened your powdered baby formula container, you typically have between 2 to 4 weeks to use it up.

    However, these are merely general trends in shelf life. You should always read and follow the manufacturer's instructions for your baby's specific infant formula and abide by the container's expiration date.

    Shelf Life After Opening: Our Long Shelf Life Powdered European Formulas

    The shelf life of baby formula will vary between brands depending on the nutrients used in the formulation and the manufacturing process. Another area of distinction is that European organic formulas may need to be used before the 30-day shelf life typical of American formulas.

    As for the brands that we offer here at Organic's Best, here is a quick breakdown of their shelf lives after opening:

    formula shelf life

    Kendamil: 4 weeks

    Nannycare: 4 weeks

    Jovie Goat: 4 weeks

    Jovie Cow: 3 weeks

    HiPP: 3 weeks

    Holle Dutch: 3 Weeks

    Holle German: 2 weeks

    Lebenswert Bio: 2 weeks

    Löwenzahn Organics: 2 weeks

    HiPP Ready-to-Feed: 24 hours

    If you only use infant formula for supplementing, you likely go through containers of formula more slowly. In this case, we recommend opting for brands that give you more leeway in terms of how long you have to use up the formula after opening, like Kendamil, Nannycare, or Jovie Goat, which last for a whole month after they've been opened!

    For the expiration dates of our sealed powdered formulas, we guarantee a shelf life of at least 6 months or more in the future. This allows parents to stock up on their baby's formula and take advantage of our bulk pricing deals without having to worry about their supply going off before they get to use it.

    What Happens if Baby Drinks Old Formula?

    Remember, expired baby formula loses its nutritional value and spoils. That means if you accidentally gave baby old formula, they could experience gastrointestinal upset and general discomfort.

    If your baby has drank spoiled formula, it's essential to seek medical attention immediately, especially in the case of fever.

    See our list below for potential symptoms of baby drinking spoiled formula.

    Check for any unusual or foul smells, such as a moldy, sour, or chemical scent. There may also be changes in consistency, like clumping when mixing. Finally, you may also observe changes in color or the presence of mold or pests/insects in more extreme cases.

    If you detect any of these signs of spoilage, it's important to throw the infant formula away.

    Storage Tips for Keeping Baby Formula Fresh

    The best way to prevent early baby formula expiration is to make sure you're following safe storage practices. That means keeping your baby's formula in a cool, dry indoor space, such as your pantry, and closing the container tightly after each use. It's also essential to store baby formula away from heat, humidity, and direct sunlight, all of which can cause the formula to go rancid before the expiry date.

    Answering Your Questions About Expired Formula Powder

    For those of you short on time who need quick answers or if you simply enjoy a concise summary to help you digest information, here are some Q and A's covering the key points about when does formula expire and what to do with expired formula!

    Does Baby Formula Expire if Unopened?

    As long as your infant formula is unopened, sealed, and stored properly, it should keep until the "Use By" date on the container. However, if it has been stored in unsafe conditions or was improperly sealed, the formula may spoil.

    Can You Use Expired Formula?

    Sometimes, in emergency circumstances such as the 2022 formula shortage, parents wonder: Can I use expired formula or is expired formula safe? The answer is a resounding no! The nutrients in infant formula can degrade past the expiry date, potentially offering your baby an insufficient amount of calories, and harmful bacteria can grow with time.

    Can I Save Formula that Baby Didn't Finish?

    No, it is not safe to save leftover formula after feeding your baby for later use. The reason for this is that saliva from your baby's mouth enters the bottle and can lead the the growth of dangerous bacteria.

    So if your baby doesn't finish their bottle, don't be tempted to store it in the fridge and heat it up for later; the safest thing you can do is simply throw it away.
