The ongoing Cyclospora investigation is another reminder of what food safety experts know well: protecting consumers takes more than one control point or one company’s actions. It requires strong systems, disciplined execution, and constant vigilance across the entire food supply chain. As public health officials continue to learn more, this is an important moment for the industry to stay focused on the fundamentals that help prevent risk before it reaches consumers.
What is Cyclospora?
Cyclospora is a microscopic parasite that causes an intestinal illness known as cyclosporiasis. Infection typically occurs through contaminated food or water, not through direct person-to-person contact. In the United States, cases tend to increase during the spring and summer months, often prompting heightened attention across the food industry.
What Makes Cyclospora So Challenging?
Cyclospora is challenging because the most important control point is often before product reaches a restaurant, retailer or food manufacturing facility. Understanding those conditions like worker health and hygiene, toilet and handwashing access, septic system management, and agricultural water quality are especially important at the farm and packinghouse level.
It is also challenging because parasites are difficult to inactivate. The CDC recommends thorough washing of produce as part of safe food handling, but washing alone cannot guarantee removal of Cyclospora. The FDA states that chlorine and other common antimicrobial chemical treatments are not considered effective. In practical terms, there is no single product or step that should be positioned as a complete solution.
That does not mean cleaning and sanitation are unimportant. They remain essential to prevent cross-contamination, support sanitary operations, and allow facilities to reset after potentially contaminated products have been handled.
Prevention Starts with the Basics
Today's food system is highly interconnected. Products move through farms, processing facilities, distribution centers, retail locations, and restaurants before reaching consumers. Protecting public health depends on strong systems at every stage and on people, processes and controls working as intended along the way.
For food manufacturers, retailers, restaurants and foodservice operators, six fundamentals continue to make a difference for food safety outcomes:
- Start with supplier controls. Supplier approval, produce safety expectations, agricultural water management, worker hygiene programs, and traceability are critical when the risk may originate upstream.
- Make hygiene non-negotiable. Worker health, handwashing, restroom access, and exclusion of ill employees are not administrative details. They are core food safety controls, particularly when the hazard is associated with human fecal contamination.
- Treat sanitation as a daily discipline. Regular cleaning and sanitizing of food-contact surfaces, utensils and equipment help minimize opportunities for cross-contamination.
- Maintain traceability and be ready to act. The ability to identify product sources, lot codes, distribution paths and affected locations quickly can make the difference between a contained event and a broader disruption.
- Train continuously. Food safety procedures are most effective when employees understand them, follow them, and reinforce them every day.
- Verify what you expect. High-performing food safety programs have policies and procedures in place that are measured, monitored, and verified.
These measures matter every day. They become even more important when the industry is responding to an active food safety event.
Leading organizations increasingly focus not only on having food safety procedures in place, but also on verifying that those procedures are consistently executed and effective. Strong food safety cultures are built through accountability, measurement, and continuous improvement.
The Work Consumers Don't See
Consumers often think about food safety when they see a headline. The work itself happens long before that headline appears.
It happens through supplier oversight, inspections, training, sanitation, monitoring, and verification. It happens through the consistent execution of procedures repeated thousands of times every day across the food system.
This is where Ecolab can be a valuable partner. For more than a century, Ecolab has helped food manufacturers, processors, retailers, restaurants and hospitality operators build stronger food safety programs, improve sanitation practices, and drive greater operational consistency. Our role is to help customers make science-based decisions and execute the fundamentals with consistency.
One of the most consistent lessons we see is that prevention is most effective when food safety is embedded into daily operations, reinforced through training, and supported by ongoing verification.
Every day, our teams work alongside customers to strengthen food safety practices, improve sanitation programs, and build greater consistency and confidence in their operations.
Continuous Improvement Protects People
Outbreaks are never just about one product, one facility, or one point in time. They test the strength of the entire food safety system. They also create an opportunity to learn, improve, and reinforce the controls that protect public health.
While food safety challenges remain, the industry has made significant progress through stronger supplier oversight, sanitation programs, employee training, and operational controls. Those efforts have improved food safety outcomes and helped build confidence in the food system.
The scale of that impact matters. In 2025, Ecolab helped protect 1.7 billion people from foodborne illnesses and infections through our solutions, services, and expertise. By 2030, we aim to protect 2 billion people from foodborne illness and infections, together with our customers.
As more information becomes available from the current investigation, the industry will have an opportunity to learn from this event and strengthen the systems that help keep food safe.
There is no substitute for doing the fundamentals well every day. And there is no substitute for leading with science.
At Ecolab, we remain committed to helping our customers do exactly that.
