Cyclospora in Berries: San Diego Outbreak Guide

Cyclospora outbreaks linked to contaminated berries have affected California consumers multiple times in recent years, with San Diego County facing documented cases. This parasitic infection spreads through contaminated produce—especially imported raspberries, blackberries, and strawberries—and can cause severe gastrointestinal illness. Understanding the local response and your protection options helps you avoid foodborne illness.

San Diego Cyclospora Outbreak History

San Diego County has experienced Cyclospora illnesses linked to berry consumption, particularly during summer months when consumption peaks. The CDC and California Department of Public Health (CDPH) investigate clusters involving frozen and fresh berries, often tracing sources to specific growing regions in Central America and Mexico. The San Diego County Health and Human Services Agency (HHSA) maintains outbreak surveillance and works with local providers to identify cases. Past investigations revealed that imported raspberries and blackberries posed the highest risk, prompting enhanced import monitoring by FDA field offices in California.

How San Diego Health Departments Respond

When suspected Cyclospora cases emerge, the San Diego County HHSA epidemiology unit coordinates with the FDA and CDC to trace source products and issue public health alerts. The county's Food and Drug Branch inspects retail locations and investigates point-of-source contamination. CDPH publishes updates through its website and media channels; consumers can subscribe to CDC outbreak notifications at cdc.gov/foodsafety. Real-time alerts from platforms monitoring FDA and CDPH sources allow residents to act immediately rather than waiting for traditional health department announcements.

Consumer Safety Tips & Real-Time Protection

Wash berries under running water before eating—though thorough washing does not eliminate Cyclospora—and consider cooking berries when possible, as heat kills the parasite. Check FDA Enforcement Reports for active recalls on berries and frozen berry products. Vulnerable populations (immunocompromised, pregnant, elderly) should avoid raw imported berries during high-risk periods.
