Unwarmed breastmilk that comes straight from the refrigerator can be left out for a bit longer but ideally should be served within 4 hours. If your baby does not finish the bottle, discard any unused milk after 2 hours at room temperature.
Using Thawed Breastmilk
Thawed breastmilk—whether from the refrigerator or previously frozen—should also not be refrozen. You can keep it at room temperature for up to 2 hours after thawing. The maximum duration for thawed breastmilk from a refrigerator is 24 hours before it should be discarded.
Key Considerations for Breastmilk Safety
Ensuring the safety of breastmilk extends beyond just understanding time limits. Here are some critical factors to consider:
Signs of Spoiled Breastmilk
Breastmilk typically has a sweet, mild odor, but if you notice any of the following signs, it may be spoiled and should not be consumed:
- Sour or rancid smell
- Change in color or consistency
- Clumping or separation that does not resolve upon shaking
Using sensory evaluation can often help determine whether or not breastmilk is still safe for consumption.
Proper Handling Techniques
Ensuring that breastmilk remains fresh involves more than just managing time. Here are some handling techniques that aid in maintaining the quality of breastmilk:
- Wash Hands Thoroughly: Always wash your hands before expressing milk to prevent contamination.
- Avoid Touching the Inside of Containers: Keep your storage containers clean and avoid touching the rim or inside to reduce bacteria transfer.
- Label Your Milk: Clearly labeling containers with the date and time of expression helps track storage limits.
Knowing When to Discard Milk
If uncertainty arises regarding whether to use breastmilk or not, remember that it’s always safer to discard than risk your baby’s health. Trusting your instincts and assessing using sight and smell are excellent tools for making this judgment.
