The reporting

A neutral summary of the key facts most outlets agree on, drawn from reporting across the political spectrum.

The CDC expanded its cyclosporiasis outbreak investigation to Illinois, Kansas, Oklahoma and Pennsylvania, bringing the outbreak linked to shredded iceberg lettuce to nine states. The newly linked states join Indiana, Kentucky, Michigan, Ohio and West Virginia, with Michigan identified as a major hotspot. Federal data cited in the reports show 4,173 laboratory-confirmed domestic cases under investigation and more than 11,500 suspected or reported illnesses this season. Officials are investigating lettuce from central Mexico, including products served at Taco Bell, as the likely vehicle.
