Food Safety

Cold Storage

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.

Refrigeration will slow, but not stop, the growth of microbes.

Freezing will stop most bacteria from growing, but will not destroy them.
