Households had refrigerators, but it also had a lot to do with the improvement of processing. Homegenization and pasteurization meant that with refrigeration milk would last much longer rather than spoiling in a few days.
I'm pretty sure there's a similar story with flour, it used to rot pretty quickly and every town had a mill because flour wouldn't make it too far out of town before spoiling (plus demand for quite a few bakerys in every town too). Now we have flour that'll last a year in your pantry because of additives. Not sure when this would have changed, maybe the early 20th century? Maybe even the 1950s and on?
