Can You Put Already Heated Breast Milk Back in the Fridge?
The question of whether heated breast milk can be safely returned to the refrigerator is one that many new parents grapple with. The answer is nuanced and hinges on several important factors regarding safety and best practices for milk storage.
The General Guidelines
According to expert sources, once breast milk has been warmed, it should ideally not be returned to the fridge if it has been left out for more than two hours. This is primarily due to the risk of bacterial growth that can occur when milk is heated. The Centers for Disease Control and Prevention (CDC) emphasizes that breast milk should be handled with care to ensure it remains safe for infants.
Specific Conditions for Re-refrigeration
However, there are some exceptions to this rule. If the warmed breast milk has not been consumed and is returned to the fridge within four hours, it may be safe to refrigerate it again. This is contingent on the milk being kept at a safe temperature and not being left out at room temperature for too long.
The Mayo Clinic also supports this guideline, noting that breast milk can be stored in the refrigerator for up to four days, but it should be chilled immediately after expression to maximize its safety.
Risks of Bacterial Growth
The primary concern with reheating and then cooling breast milk is the potential for bacterial growth. When breast milk is warmed, it creates an environment where bacteria can thrive, especially if it is not consumed promptly. Experts warn against repeatedly heating and cooling milk, as this can significantly increase the risk of contamination.
Practical Advice for Parents
For parents navigating this issue, the best practice is to only warm the amount of breast milk that is likely to be consumed in one feeding. If there is leftover milk that has been warmed but not used, it is advisable to either discard it or use it for other purposes, such as a milk bath, rather than risking the health of the baby by returning it to the fridge.
In conclusion, while it is technically possible to refrigerate warmed breast milk again under certain conditions, the safest approach is to minimize the warming and cooling cycles to protect your baby’s health. Always prioritize safety by adhering to recommended guidelines and being mindful of how long the milk has been at room temperature.

Can you refrigerate breast milk after thawing and warming?

According to the CDC you should never refreeze breast milk once it’s been thawed. It’s good in the fridge for up to 24 hours after being thawed, and that’s it.

What to do with leftover warmed breast milk?

Leftover breast milk can still be used within 2 hours after the baby is finished feeding. After 2 hours, leftover breast milk should be thrown away. To avoid wasting unfed milk, consider storing, thawing, and warming it in smaller amounts. See Breast Milk Storage and Preparation for more information.

Can I rewarm breast milk twice?

When it come to heating up breast milk, it’s generally recommended that you only reheat breast milk once, maybe twice. The reasoning for this is that each time you heat and cool the milk, it can potentially degrade the quality and nutritional value.

Can you reheat milk that has already been heated?

If heated milk is left sitting in the temperature danger zone, bacteria and other harmful pathogens multiply quickly. You might think that reheating this same milk again above the 60 degrees will kill off any bacteria that may have grown during this time. This is simply not true.

Can I put warmed up breast milk back in the fridge?

Warmed milk from the fridge should be used within two hours. If it’s not used, it should be thrown away. “Once your milk is warmed, the ability of the milk to inhibit bacterial growth is decreased, so it is not recommended to place your milk back in the refrigerator,” explains Andria.

Can you reheat breast milk twice according to the CDC?

Never refreeze or reheat breast milk that’s been thawed, the CDC notes. If you’re not feeding baby immediately, keep defrosted breast milk in the fridge. If you thawed it at room temperature, the milk is good for up to two hours (after that, throw it out).

Can warmed whole milk be refrigerated again?

Whatever bacteria grew while it warmed up will still be there, and will continue to grow. Refrigeration only slows down the multiplication of bacteria.

Can you put baby milk back in fridge after warming?

Once a bottle is prepared or taken from the fridge for feeding, use the formula within 1 hour or throw it out. You cannot re-refrigerate formula once it has been warmed or reaches room temperature. The reason experts recommend you throw away unused formula is because bacteria can begin to grow.

Can you save breast milk after it has been heated?

Start counting the 24 hours when the breast milk is completely thawed, not from the time when you took it out of the freezer. Once breast milk is brought to room temperature or warmed, use it within 2 hours. Never refreeze breast milk after it has thawed.

What do you do with leftover warmed breast milk?

After 2 hours, leftover breast milk should be thrown away. To avoid wasting unfed milk, consider storing, thawing, and warming it in smaller amounts. See Breast Milk Storage and Preparation for more information.
