The next time you open your fridge, take a second to behold the miracles inside of it: Raspberries from California, butter from New Zealand, steak from Nebraska. None of that would have been remotely possible before the creation of the cold chain.  The cold chain is the name for the end-to-end refrigeration of our food from farm to truck to warehouse to grocery store and ultimately to our fridges at home. And it’s one of the great achievements of the modern world.  On today’s show, Nicola Twilley, food journalist and author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves, tells us the story of how our world got cold, and what that’s meant for the economy.   We’ll hear about two pioneers of cold: The cheapskate meat baron Gustavus Swift, and the train-hopping chemist Polly Pennington. And we’ll take a look at whether all this refrigeration might have created some new problems.  Subscribe to Planet Money+ Listen free: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.

  • This is Planet Money from NPR.

  • The other day, I donned a hair net and a very unfortunate beard net.

  • And got to visit a place I'd wanted to for a very long time.

  • Shipping dock, smell of produce, pallets, racking, the whole thing.

  • This place is low-key.

  • one of the wonders of the modern world.

  • It's an enormous refrigerated warehouse filled with enough food to feed an entire city.

  • My guide to this miracle is Nicola Twilly.

  • We're heading in.

  • It's noisy.

  • Food journalist hosted the podcast Gastropod,

  • an author of a recent book about refrigeration called Frostbite.

  • Nikki has become obsessed with places like this.

  • She spent the last decade visiting them and even worked in some of them.

  • It's a cool, it's a cool world.

  • The warehouse we're in today is enormous, the size of two football fields.

  • Don't get run over, careful, careful.

  • Fruits and veggies are coming in from all over the world and going out to supermarkets and restaurants across Southern California and beyond.

  • There are all these storage rooms with very particular microclimates.

  • Each the perfect temporary home for a bell pepper or a jackfruit or a horseradish.
