Can You Thaw Breast Milk Then Refreeze It?
Breast milk that is once thawed should never be kept in the freezer again as refreezing results in bacterial growth and also, leads to major loss of nutrients. So, it is best to use the breast milk within 2 hours once it is completely thawed and warmed.
Unfortunately, you cannot thaw refrigerated breast milk, and it must be used within 24 hours after it has finished chilling (not when a power failure starts, or you remove it from your fridge). Breast milk kept cold in a refrigerator is good for 24 hours after it has fully thawed (not from the moment you took it out of the freezer). Once breast milk that has been frozen before is thawed, it may be stored in the fridge, but should be used within 24 hours.
Freshly expressed breast milk may be stored at the back of a deep freezer for up to 12 months, but using the milk within six months is ideal. You can safely store frozen milk in a freezer for up to six months, but it is best if you can use it within one month of freezing. If the freezer is a chest or a deep freezer (4degF or -20degC), milk can be frozen for up to 12 months. You may store the milk in a refrigerator for 3-5 days, moving it into a freezer at any time before this time is up.
To retain maximum nutrients, though, it is best to freeze your milk ASAP, ideally within the first 3 days. If there is still lots of snow on the ground, you may want to keep your milk in a snowbank, out of the sun, until power is restored, and then put your milk in your fridge ASAP. If the milk still has ice crystals, then it is still considered frozen — you are safe to either use the milk or return it to your working freezer.
Based on this study, it is also likely that it is safe to use the milk even though it has fully thawed, with no ice crystals left. It is important to note, that if your child has already been drinking milk — they should NOT refreeze the milk (even if there are still ice crystals in the milk as you give it to them). According to KellyMom, if your milk, which was frozen before, has ice crystals and has not fully thawed, then it is still considered frozen, and thus is safe to refreeze.
While more research is needed to determine whether thawed formerly frozen milk is able to thaw and safely be used again, many experts advise to throw out any thawed milk not used within 24 hours. Based on this data, it appears that nonpasteurized milk that has been allowed to thaw for up to 8 hours can safely be refrozen. It appears that unpasteurized milk that has been accidentally thawed remains safe for consumption, provided that it has not been left too long in the unthawed state. A study published in the journal Breastfeeding Medicine found that there was no bacteria accumulation or any major reductions in nutrition of breastmilk that had been fully thawed for up to eight hours in a refrigerator before being refrozen.
Refrigerated or frozen milk will usually have separated into fat and non-fat layers, but if it remains lumpy after spinning, it might be spoiled. Sometimes milk that has been frozen and thawed can smell soapy because of the fat content, but that is different from the smell of bad milk, and does not mean that the milk is unsafe.
To thaw more quickly, or to warm cooled milk, place a container of milk under hot running water. No, but you can heat a pot of water on a burner, take it off the heat, then put your container of milk in the hot water. If you heat milk in the water or in the heated bottle, or after it has reached room temperature, use this milk within two hours, not to refreeze. You can also use a bottle warmer, or place the refrigerated milk that will be used next day overnight in a cooler.
Once it is thawed, you can thaw frozen breast milk and use immediately, let it sit out at room temperature for up to four hours, or place it in the fridge for up to 24 hours. Storage Guidelines for Freshly Expressed Breastmilk (For Healthy 2-3-Year Old Infants) If you have expressed your breastmilk cleanly and safely, you can store it at room temperature, the fridge, or in the freezer, depending on how quickly you wish to use it.
You can, so long as the first babys overnight feed occurs within four hours — the two hours for the newly expressed milk to reach room temperature, and the two hours that you are allowed to leave it outside, according to the CDC guidelines discussed above. In the past, you recommended that you leave the freshly pumped milk out until after the first nighttime feeding of baby (4-8 hours*). If baby goes to sleep at 8 pm, you remove the freshly pumped milk, go to sleep at 11 pm, and baby usually wakes for feedings before 3 am, this would be okay.
Current guidelines suggest using milk within 24-48 hours (24 hours if the baby is preemie or has immune issues requiring extreme caution) rather than refrigerating. You may wish to keep out only as much of your refrozen milk as you believe you will use in 24-hours, and refreeze the remainder. Once your breastmilk has thawed at room temperature or warmed up from being stored in your fridge or freezer, use within 2 hours. When the breastmilk has thawed completely, it is fine to store it in the fridge for at least one day (24 hours) without harming its flavor or texture.
Because breastmilk expands during freezing, keeping milk at 2-4oz increments helps to avoid filling up your bag too much (or thawing more milk than is needed to feed).
According to some sources, such as The Cleveland Clinic and KellyMom, it is likely safe to give your toddler any milk left after the first feed for up to 2 hours. Some older reports suggested refrozen, refrigerated breast milk was fine, but most experts now agree there is not enough research to back that up, and so say that defrosted breast milk is best used within 24 hours.
How to thaw breast milk from the freezer fast?
Hold the milk canning jar under heated running water to fast defrost frozen milk or to heat chilled milk. Alternately, put it in a heated water-filled cup, pot, bowl, or basin. Never microwave or defrost milk in extremely hot water. As a result, some of the milk’s beneficial qualities are diminished.
How long is breast milk good for after thawing?
After defrosting frozen breast milk in the fridge, utilize it within 24 hours. Try to use the milk within 2 hours after the milk is defrosted and matches with the normal room temperature. Otherwise, it will not be a wise decision to use it, better to discard it.
