A multistate cyclosporiasis outbreak linked to shredded iceberg lettuce continues to expand, according to reports from U.S. outlets. The outbreak is now reported in 15 states after the addition of six jurisdictions since the most recent update. ABC News identifies the newly reported states as Arkansas, Iowa, Missouri, Nebraska, New Hampshire and North Carolina. NBC also reports that the outbreak grows by six additional states, citing a source familiar with the matter, without naming them in its summary.

Cyclosporiasis is an intestinal illness caused by the parasite Cyclospora. The outbreak is being associated with the consumption of shredded iceberg lettuce. Authorities continue to track cases across states and update the geographic scope as additional information becomes available. The reports reflect a widening spread of confirmed or suspected cases tied to the same contaminated food source, but they do not include new details about case counts, hospitalizations, or the specific lettuce products involved.
