The ongoing Cyclospora outbreak has now sickened nearly 23,000 people across 47 states, with more than 500 hospitalizations and two deaths, according to public health officials. Michigan health authorities announced on Monday that the two fatalities were linked to the outbreak, and both individuals had significant underlying health conditions that may have been exacerbated by cyclosporiasis and dehydration. Notably, both deceased fell ill before Taylor Farms recalled shredded iceberg lettuce grown in Mexico, which has been implicated as a source of contamination.

Cyclospora is a unicellular parasite that spreads through human feces, often via contaminated fresh produce. In past outbreaks, the parasite has been traced to fresh herbs, raspberries, green onions, and snow peas. The current outbreak, which began in June, has proven unusually severe, as cyclosporiasis fatalities are extremely rare.

Despite the scale of the outbreak, federal health agencies have been slow to update the public. On Tuesday, the Washington Post reported that federal officials expanded the list of states with linked cases from 9 to 15. However, as of Wednesday, the CDC and FDA public outbreak pages have not yet been updated with the expanded state list. An HHS spokesperson told Ars Technica on Monday that outbreak information would be updated sometime "this week," but the delay has drawn criticism. Additionally, sources cited by the New York Times indicate that the CDC plans to set up a formal response team sometime this week, a step that comes months after cases began accumulating.

The slow federal response stands in stark contrast to the urgency of the situation. Consumers rely on updated state lists to make informed choices about produce, and the lack of timely public information complicates prevention efforts. Michigan health officials have urged clinicians to consider Cyclospora in patients with prolonged diarrhea, especially those with underlying conditions.

As federal agencies work to update their pages and establish a formal response team, the public is left waiting. State and local health departments are left to fill the information gap until the CDC and FDA catch up.
