Understand the Science
In 2026, the USA has grappled with large foodborne disease outbreaks, the most notable due to Cyclospora cayetanensis linked to iceberg lettuce. This outbreak, affecting thousands, has made international news and drawn criticism of the USA’s reduced national capacity to conduct surveillance for foodborne diseases.1 Although foodborne diseases are more frequent in countries with inadequate sewerage and water and food safety infrastructure, they occur everywhere.
