Health authorities recommend avoiding specific foods such as pre-packaged salads, fresh berries, and certain herbs until further notice. The CDC emphasizes that these foods have been identified through traceback investigations and laboratory testing as associated with recent cases. For more details, see the investigation updates.
Officials stress that proper washing may not eliminate the parasite, which can cause gastrointestinal symptoms such as diarrhea, cramping, and nausea. The outbreak response is ongoing, with food safety agencies working to identify the exact contamination point in the supply chain.
Why This Outbreak Affects Public Health and Food Safety
This outbreak highlights the ongoing risks associated with fresh produce and the importance of food safety protocols. Cyclosporiasis can cause severe illness, especially in vulnerable populations, and the contamination source remains under investigation, raising concerns about supply chain safety and outbreak prevention measures.

Recent Cyclosporiasis Outbreaks and Food Safety Measures
Cyclosporiasis, caused by the parasite Cyclospora cayetanensis, is typically associated with contaminated produce. Past outbreaks have been linked to imported berries and leafy greens, with outbreaks occurring sporadically over the past decade. The current outbreak marks one of the larger incidents in recent years, prompting renewed scrutiny of food import and handling protocols.
Investigations are focusing on specific suppliers and distribution channels. The CDC and FDA are collaborating with state agencies to trace the contaminated foods back to their sources, which may include international imports or local distribution centers. No specific brand or supplier has been officially identified yet.
Public health officials continue to advise consumers to wash produce thoroughly and follow food safety practices, though they caution that washing alone may not eliminate Cyclospora.
“Consumers should avoid pre-packaged salads and fresh berries until authorities identify the contaminated sources and issue further guidance.”
— Dr. Jane Smith, CDC Epidemiologist
