Iceboxes and refrigerators keep food cold and control the growth of harmful bacteria.
Until the invention of refrigeration (ca. 1890), people who lived in cold climates would
store certain kinds of food in ice or snow, or in an underground root cellar. Even well
into the twentieth century, many homes had a cold storage room or a root cellar.
Blocks of ice, cut from lakes and ponds, were used to keep food cold.

Refrigeration will slow, but not stop, the growth of microbes.
Freezing will stop most bacteria from growing, but will not destroy them.
