Handling of breast milk
If breast milk has been frozen, then thawed in the refrigerator, is it ok to freeze it again or must it be discarded? If it is ok to freeze it again, what is the timeframe it must be frozen again before it spoils in the refrigerator?
Thawed product should not be refrozen after thawing. It should be consumed after thawing and any leftovers discarded. I suggest freezing the product in individual one use portions, so there is no need to thaw the whole batch. Be sure that containers used to hold the product are clean and seal properly and that the product is handled in a sanitary manner so to avoid contamination.
Thawing exposes the product to bacteria/mold/etc.present in the environment, particularly the ones suspended in the air. Freezing does not kill all of them but slows down their growth, so if a thawed product gets refrozen, once re-thawed, all those bacterias/molds/etc.. will re start reproducing/growing making the product unsafe.
Remember, if in doubt throw it out.
