Cyclosporiasis Outbreak Linked to Shredded Lettuce Expands to Six Additional States

Why it matters locally: Foodborne illness outbreaks, even those originating elsewhere, pose a public health concern that can affect Arizona residents through contaminated food products distributed statewide.

A cyclosporiasis outbreak, which officials linked to shredded iceberg lettuce, has now expanded to six more states. A source familiar with the situation confirmed this development. Cyclosporiasis is an intestinal illness caused by the _Cyclospora cayetanensis_ parasite. Individuals can become infected by consuming food or water contaminated with the parasite. Symptoms typically include watery diarrhea, loss of appetite, weight loss, abdominal cramps, bloating, nausea, and fatigue. The illness can last from a few days to a month or longer, and symptoms may recur.
