How Long Does Baby Formula Last?

One of the first questions many parents ask is, Does baby formula expire? The short answer is yes, and knowing the timelines can save you from a lot of guesswork. Let's break it down.

Unopened cans of Baby Formula typically stay good for 1 to 2 years. You'll find a "use by" date stamped on the bottom or side of the can, often looking like "06/2026." Here's a heads-up for those shopping with MyEuroMall.com: many of our products are German-manufactured, and they use the DDMMYYYY date format. So, a date like "03092025" means September 3, 2025, not March 9, 2025, as you might expect with the U.S. standard. If that date has passed, don't take the risk, toss the can out, as it might not be safe or nutritious for your baby anymore.

Once you open a can of powder formula, it lasts 1 month. To avoid confusion, write the opening date on the lid with a marker to keep track. Liquid concentrate or ready-to-feed formula has a shorter window, lasting just 48 hours in the fridge, so you'll need to use it quickly. After mixing, prepared formula lasts 1 hour at room temperature, think of it sitting on the counter during a busy morning. It’s safe for 24 hours in the fridge, but don’t freeze it; freezing can ruin the nutrients and texture, making it less beneficial for your little one.
