We use the volu-feeders to store EBM. Here's some interesting info. We had a
mom who hadn't been cleaning her pump correctly and it stopped working due
to the valve being coated with milk fat. That's when they called me. We did
random EBM cultures of the milk she had frozen, milk that had been pumped
with a "dirty" pump. Not one culture grew anything. Breast milk is
wonderful.
