I thought I had milk that would go bad too. Then at a LLL meeting, one leader said, "I'll bet if you hand express it into a clean, sterile, glass that it doesn't go bad." I did so, and milk that had been going bad in a half hour, was fine 2 hours later on the counter. She suggested, and it makes sense, that I wasn't adequately cleaning my pump. I was washing it per manufacture instructions, (using the dishwasher), but it seems that it needed to be boiled and scrubbed. Then the problem went away.
