Can you refreeze breastmilk after its been thawed?

The Complexities of Refreezing Thawed Breast Milk
Breastfeeding is a vital source of nutrition for infants, and many parents find themselves navigating the intricacies of breast milk storage and usage. One common question that arises is whether it is safe to refreeze breast milk after it has been thawed. The answer is nuanced and rooted in safety guidelines established by health organizations.
Understanding Thawing and Refreezing Guidelines
According to the Centers for Disease Control and Prevention (CDC), once breast milk has been thawed, it should not be refrozen. This guideline is primarily based on safety concerns regarding bacterial growth. When breast milk is thawed, it can become a breeding ground for bacteria, especially if it has been left at room temperature for too long. The CDC advises that thawed breast milk can be safely stored in the refrigerator for up to 48 hours, but once it has been warmed or brought to room temperature, it should be used within 5 to 8 hours.
The rationale behind these recommendations is straightforward: when breast milk is thawed, any bacteria present can become active. Refreezing the milk does not kill these bacteria; it merely pauses their growth. If the milk is then thawed again, it poses a risk of foodborne illness for the infant.
The Science Behind the Guidelines
The concern over refreezing thawed breast milk is not just a matter of preference; it is grounded in biological principles. When breast milk is frozen, the low temperatures inhibit bacterial growth. However, once thawed, the milk can enter what is known as the “temperature danger zone” (between 40°F and 140°F), where bacteria can multiply rapidly. This is why health experts emphasize the importance of using thawed milk promptly and discourage refreezing.
Interestingly, some discussions in parenting communities suggest that if there are still ice crystals present in the milk, it may be safe to refreeze it. However, this is a contentious point and not universally accepted. The consensus remains that fully thawed milk should not be refrozen.
Practical Tips for Breast Milk Storage
To avoid the dilemma of refreezing, parents are encouraged to store breast milk in smaller quantities. This way, they can thaw only what they need for a feeding, minimizing waste and reducing the risk of having to deal with leftover milk. Additionally, labeling containers with dates can help track how long the milk has been stored, ensuring that it is used within safe timeframes.
In conclusion, while the idea of refreezing thawed breast milk may seem convenient, the potential health risks associated with bacterial growth make it inadvisable. Parents should adhere to established guidelines to ensure the safety and well-being of their infants, prioritizing their health above all else.

What happens if you freeze milk twice?

Most people worry about the food safety of thawing and refreezing, but as long as it’s done right, it’s perfectly safe. The only risk you’ll take is ruining the taste and texture of the food.

What happens if I refreeze thawed breast milk?

• Refreezing breast milk that has been previously thawed can alter the composition and quality of the milk.
• Furthermore, refreezing breast milk can also increase the risk of bacterial growth and contamination, as the process of thawing and refreezing can create an environment that is favorable for bacterial growth.

How long can you keep frozen breast milk once defrosted?

Once fully thawed, previously frozen breast milk may be kept at room temperature for a maximum of two hours or in the refrigerator for up to 24 hours. Don’t thaw or heat frozen breast milk in a microwave or in boiling water.

Can breast milk come out of fridge and go back in?

Don’t put leftover breast milk back in the fridge to use later or refreeze it. It’s important to follow safety guidelines for breast milk because bacteria can grow in it if you leave it out for too long.

Can I put breast milk back in the fridge after baby drinks from it?

Any remaining breast milk left in a bottle after your baby is finished with a feeding should be used within 2 hours—or, if quickly refrigerated, used for the next feeding. You can always thaw an extra container if needed. Refrigerate or chill milk right after it is expressed.

How to know if breastmilk is spoiled?

It will also smell bad, much like spoiled cow’s milk. And, like spoiled cow’s milk, breast milk that’s old will taste sour. (It’s fine to taste your breast milk to check!) Always label your pumped milk with a time and date so you can tell how old it is.

Can frozen milk be thawed and refrozen?

The CDC says that you can refreeze thawed milk if it contains ice crystals. However, given the factors mentioned above, if you have any concerns you can always strain the ice crystals and refreeze those, and use the thawed milk according to these milk storage guidelines (LINK).

Can thawed milk go back in fridge?

Once fully thawed, previously frozen breast milk may be kept at room temperature for a maximum of two hours or in the refrigerator for up to 24 hours.

Can you freeze breast milk after unfreezing?

If you’re thawing frozen breast milk, follow these guidelines for how long the milk can be safely used. Remember: Thawed breast milk cannot be re-frozen.

Can thawed breast milk go back in fridge?

Once fully thawed, previously frozen breast milk may be kept at room temperature for a maximum of two hours or in the refrigerator for up to 24 hours. Don’t thaw or heat frozen breast milk in a microwave or in boiling water.
