   CDC Declares End to Record Cyclospora Outbreak Linked to Lettuce

   U.S. health officials have officially declared the conclusion of a massive multi-state cyclosporiasis outbreak linked to iceberg lettuce. The parasite infection sickened tens of thousands of people, making it the largest event of its kind recorded in the United States. While public health authorities have closed the chapter on this specific public health threat, investigators still have not determined the exact origin of the contaminated produce. The outbreak heavily impacted states including Missouri and Illinois before the recent declaration by the Centers for Disease Control and Prevention.

   Why it matters

   Cyclosporiasis is a gastrointestinal illness caused by a microscopic parasite that often spreads through contaminated food and water. This particular event stands out as the largest outbreak of its type in U.S. history due to the unprecedented scale of infections across multiple states. Resolving the public health emergency removes immediate danger from the specific produce items involved, although questions regarding supply chain contamination remain open.

   What is confirmed

   • The Centers for Disease Control and Prevention declared the end of a record U.S. cyclosporiasis outbreak linked to iceberg lettuce.
   • The parasite outbreak sickened tens of thousands of people.
   • The event affected states including Missouri and Illinois.

   What to watch next

   • Any future updates from health officials regarding the exact origin of the contaminated iceberg lettuce
   • New safety protocols or supply chain inspections for produce distributors
