Cyclosporiasis Map 2026, Foods to Avoid as Outbreak Spreads to 47 States

Key Points:

• Nearly 23,000 confirmed and probable cyclosporiasis cases have been reported across 47 U.S. states since May 1, with Michigan hardest hit, reporting over 12,200 cases and 193 hospitalizations.
• The CDC and FDA have linked a major outbreak spanning 15 states to shredded iceberg lettuce supplied by Taylor Farms from central Mexico and served at Taco Bell, leading to a recall and removal of the lettuce from Taco Bell's supply chain.
• Cyclosporiasis is caused by the Cyclospora parasite, transmitted through food or water contaminated with feces, causing severe diarrhea and gastrointestinal symptoms; it is treatable with antibiotics but can last weeks if untreated.
• Multiple outbreaks may be occurring simultaneously, with investigations ongoing into other potential sources such as fresh parsley and cilantro, and health officials warn that cases could continue rising through August.
• Preventive measures include thoroughly washing produce, cooking food to at least 158°F, avoiding recalled products, and seeking medical care if symptoms develop; despite the outbreak, experts advise maintaining consumption of fresh fruits and vegetables while staying informed on recalls.
