Susan Mayne, who led the U.S. Food and Drug Administration’s Center for Food Safety and Applied Nutrition, has issued a warning that public health messaging around the 2026 cyclospora outbreak contains a dangerous contradiction: consumers are being told to reduce fresh produce consumption while simultaneously being advised to eat more plant-based foods for better health outcomes.
Key takeaways
- A cyclospora outbreak linked to fresh produce has created conflicting public health guidance on produce consumption
- Mayne argues consumers should not face a trade-off between food safety and nutritional benefits of fresh fruits and vegetables
- The FDA and food safety authorities must strengthen detection and monitoring systems rather than discourage fresh produce intake
- Enhanced traceability and real-time surveillance are more effective long-term solutions than demand reduction
The contradiction in food safety messaging
During outbreak responses, public health agencies often issue precautionary guidance recommending consumers avoid specific produce categories entirely. According to Mayne’s analysis in STAT News, this approach directly contradicts concurrent nutritional messaging encouraging consumption of fresh fruits and vegetables as core components of a healthy diet.
The current cyclospora situation exemplifies this policy tension. Cyclospora cayetanensis, a parasitic protozoan transmitted through contaminated produce, has prompted warnings that discourage fresh produce consumption during peak season—precisely when such foods provide maximum nutritional value and economic accessibility for lower-income households.

“Consumers should not be faced with a trade-off between nutrition and food safety,” writes Mayne in her analysis of cyclospora outbreak response strategies.

Why detection and monitoring matter more than demand reduction
Mayne argues that recommending reduced fresh produce consumption is both ineffective as a long-term strategy and harmful to public health nutrition outcomes. Instead, she advocates for strengthened surveillance, real-time detection systems, and enhanced farm-to-table traceability that can identify contamination sources rapidly and prevent distribution of affected products.
The U.S. Centers for Disease Control and Prevention has documented that cyclospora contamination typically occurs at specific production or distribution points rather than affecting all produce in a category. This specificity means that targeted recalls—rather than broad category warnings—represent a more evidence-based response aligned with both food safety and nutritional public health goals.
Investments in real-time monitoring infrastructure, according to Mayne’s framework, would allow authorities to act on suspected contamination within days rather than weeks, reducing both infection risk and the period during which nutritional guidance must be contradicted.
Implications for consumers, clinicians, and food policy
What this means
Building safer food systems without sacrificing nutrition
The underlying systemic issue, Mayne suggests, is that food safety monitoring infrastructure has not kept pace with modern supply chain complexity. Many cyclospora detection systems remain passive, relying on clinical diagnosis confirmation rather than active environmental or product surveillance. Upgrading to rapid whole-genome sequencing, environmental monitoring at production sites, and blockchain-enabled traceability could enable authorities to issue precise, product-specific warnings rather than category-level guidance.
A more integrated approach to food safety—one that explicitly accounts for the nutritional consequences of avoidance guidance—would strengthen both food safety and population health outcomes. This requires policy coordination between food safety agencies and nutritional epidemiology bodies, and explicit incorporation of nutritional impact assessment into outbreak response protocols.
The current cyclospora outbreak reflects a gap in how modern food safety systems balance competing public health objectives. As food safety standards evolve globally, integrated surveillance systems that maintain both safety and nutritional access will become essential infrastructure for public health agencies.
