Cyclospora Outbreak Under Control: RFK Jr. Update 2026

The cyclospora outbreak that sickened thousands across the U.S. is now “under control,” according to Health Secretary Robert F. Kennedy Jr. The statement came one day after the FDA reversed a 27-state recall of shredded iceberg lettuce, citing a false positive test. Here’s what you need to know about the outbreak, the recall, and what experts are saying.

What Is Cyclospora and Why Is It Dangerous?

Cyclospora is a microscopic parasite that causes cyclosporiasis, an intestinal illness marked by watery, often explosive diarrhea. Other symptoms include loss of appetite, cramping, bloating, nausea, and fatigue. The infection can last weeks if untreated and is especially risky for the elderly or immunocompromised individuals.

How Does Cyclospora Spread?

Outbreaks are typically linked to fresh produce – especially imported berries, basil, and lettuce. The CDC reports that this year’s outbreak is likely the largest ever documented in the U.S., with more than 1,600 confirmed cases and 5,100 pending. Michigan alone reported over 6,571 cases as of Tuesday.

FDA Recall Reversal: What Happened?

The FDA initially recalled shredded iceberg lettuce across 27 states, but later reversed the decision, calling the test result a false positive. Critics argue the confusion highlights weaknesses in the national food safety system. Kennedy defended the response, stating that extensive forensics identified the source and that involved companies issued recalls.

Experts Criticize CDC’s Slow Response

Many public health experts have panned the CDC’s reaction, blaming severe cuts made by the Trump administration. The FoodNet surveillance program, which tracks foodborne illness trends, was reduced from monitoring eight pathogens to just two – shiga-toxin E. coli and salmonella – making surveillance of cyclospora optional. In 2022, FoodNet data already warned that cyclospora cases were rising.

Key Takeaways for Consumers

• Wash all fresh produce thoroughly – especially lettuce, herbs, and berries.
• Cook vegetables when possible to kill the parasite.
• Watch for symptoms – watery diarrhea, cramping, nausea – and seek medical help if persistent.
• Check FDA recall lists regularly for updates on affected products.
• Report suspected cases to your local health department to aid surveillance.

FAQ

Stay informed by following official CDC and FDA updates. If you have symptoms such as watery diarrhea or severe cramping, contact your healthcare provider immediately. Early treatment with antibiotics can shorten the illness.
