We’ve been told to “eat clean.”

More fresh produce. More leafy greens. More berries. More herbs. Farmers’ markets. Pre-washed salads. That virtuous little drizzle of olive oil that says, I have my life together.

And yet this week, nearly 2,000 people across the U.S. got sick from a parasite called Cyclospora which is linked to fresh produce.

Let that sink in while you rinse your arugula for the third time.

Because this is where things get psychologically interesting.

Public health has always leaned on the idea that if we just give people the right information, they’ll make better choices. Eat this, not that. Do more of this, less of that. Choose wisely. Be well.

But what happens when the “right” choice still carries invisible risk?

What does that do to our sense of control?

We like to believe health is a series of good decisions stacked neatly on top of each other. A kind of moral math. I did the right thing, therefore I should be safe. But outbreaks like this quietly disrupt that narrative. They introduce something far less comforting. Uncertainty!

And humans? We don’t love uncertainty. We negotiate with it. We try to outsmart it. We double-wash, triple-check, switch stores, switch brands, convince ourselves that this bag of lettuce is somehow safer than the last.

(It might be. It might not be.)

This isn’t about fear-mongering. It’s about acknowledging reality. Our food system is global, complex, and increasingly fragile. The distance between farm and fork is long and not always transparent.

And yet, the messaging hasn’t quite caught up.

We still place the burden on the individual. Eat better. Choose smarter. Do your part.

But how much control does the average person actually have when the risk lives upstream in supply chains, in distribution systems, in processes they’ll never see?

There’s a quiet psychological cost to this mismatch. When people follow the rules and still get sick, trust erodes. Not all at once. Just a little. A slow drip.

And over time, that drip matters.

Because public health doesn’t just run on data and guidelines. It runs on belief. On the fragile, necessary assumption that the system behind the advice is working.

So maybe the next evolution of public health isn’t just about behavior change.

Maybe it’s about system reliability.
Transparency. And rebuilding trust in the invisible structures that are supposed to keep us safe.

Because “eat clean” only works if clean actually means safe.
