Food Safety News reported the development on 2026-07-15. Public health officials have not weighed in on why there are so many infections this year.
The report places the news in a wider commercial context. Michigan is reporting more than 400 new Cyclospora infections overnight. As of today, Michigan’s state health department had counted 3,762 patients compared to 3,309 confirmed patients on July 14. Those state officials reported on July 13 that they believe lettuce and/or salad mixes are the source of the parasite, but they said there is no single grower, supplier or brand identified yet.
For the food sector, the practical implications extend beyond the immediate announcement. The parasitic infections hit outbreak status in June, with patient counts greatly exceeding previous years. The Centers for Disease Control and Prevention reported on July 14 that it had counted 843 confirmed patients in 34 states, with 5,100 more suspected patients. By this time in 2025 the CDC had counted 249 confirmed patients.
Attention now turns to how companies, customers and regulators respond. One such cluster includes Michigan along with New York and Ohio, which are each reporting several hundred confirmed patients. The Food and Drug Administration is tracking five outbreaks of infections, but its numbers are drastically lower than numbers from states or the CDC. For one of the outbreaks the FDA is referencing the CDC investigation.
