The headlines are alarming: a growing outbreak of cyclosporiasis, an intestinal illness caused by the parasite Cyclospora cayetanensis, has sickened hundreds of people across the Midwest and prompted investigations by state and federal health officials. While the source of the contamination remains under investigation, the outbreak raises a larger question that extends beyond one contaminated food item.
What if the bigger story isn’t what made people sick but the system that allowed it to happen?
That question sits at the center of what I call The Systems Lens, an approach that looks beyond headlines to examine the infrastructure, policies, and processes shaping our everyday lives.
What happened?
According to the U.S. Centers for Disease Control and Prevention (CDC), Cyclospora is a microscopic parasite that spreads through food or water contaminated with human fecal matter. Unlike many stomach viruses, it is not typically transmitted directly from person to person because the parasite requires time in the environment to become infectious. Fresh produce has historically been associated with outbreaks because many fruits and vegetables are consumed raw and receive minimal processing before reaching consumers.
Health officials are continuing to investigate the current outbreak, and, as of publication, they have not identified a single confirmed food source responsible for every reported illness.
Why did it happen?
That is where the conversation often stops. News reports understandably focus on identifying the contaminated product. Public health investigators work to trace illnesses back through farms, distributors, and retailers. Those efforts are essential.
But there is another question worth asking.
How does human fecal contamination reach fresh produce in the first place?
The answer is rarely simple.
Contamination can occur through improperly treated irrigation water, sewage entering agricultural water supplies, contaminated wash water used during processing, flooding events, or inadequate sanitation infrastructure for agricultural workers. Each represents a different point where a safeguard intended to protect the food supply may have failed. None of these scenarios automatically means individuals are defecating in crop fields. More often, they reflect failures in water management, sanitation systems, or food-processing infrastructure.
Why should people care?
Food safety is not created at the grocery store. By the time lettuce, herbs, or berries reach your shopping cart, they have traveled through an interconnected system involving water management, agriculture, transportation, food processing, regulation, and retail distribution.
Every step depends on the one before it.
When one layer of protection fails, another is supposed to prevent contamination from reaching consumers. A widespread outbreak suggests that multiple safeguards may have broken down somewhere along the chain, even if investigators have not yet determined exactly where.
This isn’t about assigning blame to a particular farmer, company, or country. It’s about recognizing that public health depends on resilient systems, not perfect people.
What questions should we be asking next?
Instead of asking only, “What food made people sick?” we should also ask:
- How is irrigation water monitored before it reaches crops?
- How often are agricultural water systems tested for contamination?
- What safeguards exist to prevent wastewater from entering irrigation supplies?
- How transparent are food supply chains when outbreaks occur?
- What investments in water and sanitation infrastructure could reduce future outbreaks?
These questions shift the conversation from reacting to the latest headline to preventing the next one and building a community.
Looking through the Systems Lens
Every major outbreak tells two stories. The first is about illness. The second is about infrastructure.
While scientists work to identify the immediate source of contamination, the public has an opportunity to think more broadly about the systems that produce, transport, and regulate the food we eat every day. Understanding those systems doesn’t make us fearful; it makes us informed. And informed communities are better equipped to ask better questions, demand greater transparency, and support stronger public health protections.
Sometimes the most important story isn’t the outbreak itself.
It’s the system the outbreak exposes.

This article uses what I call The Systems Lens, looking beyond individual events to understand the structures, incentives, and relationships that shape them. If you’re curious about the broader field of systems thinking, I recommend starting with The Donella Meadows Project’s “A Visual Approach to Leverage Points.” It’s one of the clearest introductions to seeing problems as interconnected systems rather than isolated events.
