I am writing this on a plane from Seattle to New Orleans, headed to the IAFP annual meeting, where I expect this outbreak will be the subject of a great many hallway conversations. Here is where it stands as we are about to land. CDC’s outbreak page, stamped Friday, counts 1,947 people infected with
Today I fly to New Orleans for IAFP 2026, the annual meeting of the International Association for Food Protection, July 26 through 29 at the Ernest N. Morial Convention Center. It is the largest food safety conference in the world — thousands of microbiologists, regulators, quality assurance directors and academics from more than sixty
At five o’clock this morning Eastern time, the Washington Post reported that the Centers for Disease Control and Prevention has linked four more states to the Cyclospora outbreak traced to iceberg lettuce from Taylor Farms de Mexico.

He said Mexico is taking precautions anyway, and its food-safety agencies, Cofepris and Senasica, say they are running preventive inspections and traceability checks in the state.
Nearly twelve thousand cyclosporiasis cases have now been reported to the CDC this summer — 4,173 confirmed in the laboratory as domestically acquired, and more than 7,400 more still awaiting the analysis that would confirm them, many of them in Michigan and Ohio. Michigan alone counted 6,571 as of July 21, with 102 hospitalizations and
The Secretary of Health and Human Services said today that this outbreak is “under control.” I would like that to be true. Here is what the states reported while he was saying it.
Michigan added 2,408 new cases in the week ending July 18. The three weeks before that were 71, then 498, then
On Sunday I graded every trade association in this outbreak on what it said and on how it handled being overtaken by events. I need to start by grading myself, because a paragraph of mine came apart within hours of publication. I wrote that there was a positive lot and that it was detained, and
