I'm a bit behind in reading but wanted to be sure that the question
asked about yeast and milk storage was addressed. Yeast CAN survive in
refrigerated milk as well as FROZEN milk. One way to address it during
treatment is to boil the milk (and cool of course) before feeding it to
baby. The reference is Rosa C et al: Yeasts from human milk collected in
Rio de Janeiro, Brazil. Rev Microbiol 21(4):361-363, 1990.
