None of the milk developed unacceptable bacterial counts, the main concern about refreezing milk. In fact, they did not even come close.
There were some changes in vitamin content. Vitamin A levels stayed stable, but vitamin C levels decreased to about one-half when kept at room temperature for 8 hours and by one-fourth when refrigerated for 24 hours. However, the authors note that the reduced vitamin levels are considered adequate for full-term babies and older infants by the National Academy of Medicine.
Differences in fatty acids levels in the milk were considered clinically insignificant and unrelated to repeated freezing and thawing.
The authors write: “Based on these data, it appears that unpasteurized milk that has been thawed in the refrigerator for up to 8 hours may be safely refrozen….
When our power went out during the last bad storm I was freaking out about my milk. DH had to drive to like 10 different places to find ice, but we were able to keep it frozen for 3 days in the cooler.
My SIL has a generator so I will be taking my milk over there when we lose power. For now it's tucked in the very back of the freezer so hopefully it stays cold enough in there until it's safe to leave the house.
The stupid eye of the storm is headed directly toward my house. Lovely.
My milk is in our separate stand-up freezer, which should keep it frozen for 2 days. After that, we are totally using the generator to keep the freezer frozen. I would cry cry CRY rivers of ugly tears if I lost my BM stash.
