Michigan Confirmed the First U.S. Cyclospora Deaths on August 3, 2026

Michigan has recorded the first two deaths linked to cyclospora in the United States, the Michigan Department of Health and Human Services announced on August 3, 2026. Both individuals had significant underlying health conditions that the department says may have been worsened by intestinal illness and dehydration.

11,234 confirmed cyclosporiasis cases in Michigan as of August 3, 2026, up from 10,773 on July 31

That jump of more than 460 cases over a single weekend signals the outbreak is still growing. No additional demographic details about the two deceased individuals will be released, the department stated.

A Recalled Lettuce Supply and No Confirmed Source Yet

Taylor Farms De Mexico issued a voluntary recall of iceberg lettuce sourced from central Mexico on July 17, 2026. The FDA and CDC confirmed on July 24 that they are investigating a multistate outbreak of Cyclospora infections tied to the recalled product.

Michigan investigators say lettuce or salad greens remain the primary lead. No specific grower, supplier, or produce type has been confirmed as the source.

“This development highlights the importance of identifying the source of the outbreak and preventing additional illnesses.”

Cyclospora is a microscopic parasite that spreads through food or water contaminated with human fecal matter. Symptoms, which appear two days to two weeks after exposure, include frequent watery diarrhea, nausea, weight loss, cramping, and fatigue. Deaths are rare in the United States.

Federal Response Has Been Slow to Name a Source

The U.S. Department of Health and Human Services told Reuters on August 3 that it was “aware” of the Michigan deaths but offered no new investigation updates. The CDC’s most recent public update on the multistate outbreak is dated July 24, more than a week before the deaths were confirmed. The gap between federal communications and state-level case growth is widening.

What You Can Do Now

  1. Contact your U.S. senators at (202) 224-3121 and urge them to press HHS and the FDA for a faster public update on the multistate investigation. The last federal update was July 24. Demand a current status report and a named source for the outbreak.

  2. Contact the FDA directly at 1-888-723-3366 to report any illness you believe is linked to lettuce or salad greens. Early reporting helps investigators trace the outbreak faster.

  3. Discard Taylor Farms De Mexico iceberg lettuce recalled on July 17. If you have pre-cut salad greens purchased recently, MDHHS advises buying whole heads instead and removing the outer two to three leaves before eating. Cook any suspect produce to at least 158 degrees Fahrenheit.

  4. Contact your state health department if you experience watery diarrhea, nausea, or fatigue after eating salad greens. Cyclospora requires a specific stool test. Ask your doctor for it by name. Find your state health department at naccho.org/find-local-health-department.
