Recent History of Cyclospora Outbreaks and Produce Contamination
Previous Cyclospora outbreaks have been linked to various fresh produce items, often involving contaminated water or improper handling during harvesting and processing. The CDC has previously issued warnings about outbreaks associated with leafy greens and other produce, emphasizing the challenges in controlling parasitic contamination in fresh foods. The current outbreak’s link to iceberg lettuce is notable, as it is a widely consumed vegetable across the country.
“We are actively investigating the source of this outbreak and are working with partners to prevent further cases.”
— CDC spokesperson
