This is Ted Health, a podcast from Ted, and I'm your host, Dr. Shoshana Ungerleiter.

Before we get started, I need to confess something about myself. I have a weird thing about food safety.

I'm that person who's very serious about expiration dates. I get nervous about food that's been

sitting out on the counter, and I'm deeply suspicious

of leftovers when the timeline feels a little fuzzy. And yes, my family and friends make fun of me for

eating food like this forever, and I just need to relax.

And maybe they're right. But maybe this is also what happens when you're a doctor who's seen

some truly awful cases of food poisoning. I have taken care of lots of patients who started with

what seemed like a simple stomach ache and ended up hospitalized, wondering how a regular meal turned

Your lunch stops feeling quite so simple.

Food is supposed to nourish us.

It's tied to comfort, culture, celebration, and connection.

On the one hand, we live in a world where food feels safer and more abundant than ever. On the other,

foodborne illness is still very real. And the systems we rely on to keep our food safe and fresh

and available are far more complex than most of us realize.

So today we're diving into the TED Archives with two talks that approach food safety
