I have a stash of EBM in plastic bags in the back of my freezer that are about 3 months old. When I moved them recently, I noticed white spots within the milk. A Google search (unreliable, I know) resulted in many similar stories but two opinions: simply fat separation or "milk gone bad." So I thought I'd pose it to the experts here. Anyone know for certain what they may be and whether the milk is safe for consumption? I haven't thawed any yet to know if it has a strange odor. I'm planning to use them one day this week when DD is at Gramma's.
