Large US Cyclospora Outbreak Traced to Lettuce Declared Over
US Health Officials End Investigation into Cyclospora Outbreak
The Centers for Disease Control and Prevention (CDC) announced the conclusion of the United States’ largest known cyclospora outbreak, which was traced back to contaminated iceberg lettuce from a major food supplier, Taylor Farms. This outbreak led to 12,883 confirmed cases and resulted in two fatalities across 21 states.
The lettuce, processed and shipped from a central Mexico facility, caused a widespread health crisis starting from early May. The peak saw over a thousand new infections in a single day, but recent reports show a substantial decline to fewer than two infections per day by August.
Geographic Impact and Demographics
Impacts of the outbreak were most severe in states like Michigan, Illinois, Indiana, and Ohio. Women made up 56% of the infections, while men accounted for 44%, with the average age of those affected being 46. Overall, the outbreak touched 49 states, including the District of Columbia.
Ongoing Investigations and Safety Measures
While the CDC has confirmed no current risk from the specific lettuce that sparked the outbreak, caution remains advised with other potential sources of cyclospora infection. The Food and Drug Administration (FDA) continues its investigation into Taylor Farms and other cyclospora cases that emerged this summer. They emphasize the importance of adhering to rigorous safety standards in food processing and distribution to mitigate future risks.
Prevention Recommendations
The CDC advises consumers to diligently wash hands and rinse produce to reduce infection risk. Thorough washing and cooking to an internal temperature of 158°F (70°C) are recommended, as water alone may not be sufficient to eliminate pathogens. Recognizable symptoms of the illness include severe diarrhea, loss of appetite, stomach pains, and occasionally, headaches or body aches.
