Cyclosporiasis Outbreak Surges to 22,700 Cases Nationwide

Michigan health officials confirmed two deaths connected to the state's cyclosporiasis outbreak on Monday. Both individuals had significant underlying health conditions, the state health department said.

• 11,234 cases have been recorded in Michigan, with 193 hospitalizations.
• 18,000-plus domestic cyclosporiasis cases have been logged nationally this season by the CDC.
• 45 states have reported cases during what officials call an unusually severe season.
• Taylor Farms de Mexico issued a voluntary recall of all iceberg lettuce from central Mexico.

Why it matters: Cyclosporiasis is caused by a microscopic parasite spread through contaminated food or water. Health officials say death from the infection is uncommon in the United States.

• Dehydration from severe diarrhea and vomiting can complicate recovery, particularly in people with weakened immune systems.
• The outbreak has been linked to Taco Bell lettuce supplied by Taylor Farms and sourced from central Mexico.

How 57 sources split on this story

Where they split: Sources do not dispute core facts, but the CDC's July 28 update — which recorded no deaths — and Monday's state announcement create a timing gap neither federal nor state officials have publicly explained.

What’s next: Recalled lettuce products are likely already consumed or off shelves, the FDA said.

• The FDA, CDC, and state partners continue investigating multiple cyclosporiasis clusters.
• The ages and full medical histories of the two deceased have not been released.
• It is unclear whether additional deaths in other states will be linked to the outbreak.
• No federal agency has publicly explained the gap between the CDC's July 28 no-deaths report and Monday's state announcement.
