Oregon health officials are investigating two residents who developed Cyclospora infections as part of a wider multistate cyclosporiasis outbreak. The cases were reported in connection with a nationwide recall involving pre-shredded iceberg lettuce products.

The Oregon Health Authority said the illnesses are being reviewed alongside the broader outbreak, which has raised concerns about possible exposure through recalled produce. Cyclospora is a parasite that can cause cyclosporiasis, an intestinal illness that public health agencies monitor closely during foodborne outbreaks.

The investigation in Oregon comes as officials work to determine how the local cases fit into the larger national picture. The recall of pre-shredded iceberg lettuce has become a central focus because the two Oregon infections have been linked to the same ongoing outbreak.

State health authorities are continuing to track the situation for any additional related illnesses. The Oregon cases add to the growing attention on the recalled lettuce products and the multistate effort to identify the source and scope of the outbreak.
