In 2026, the cyclosporiasis outbreak has become a national concern, with more than 1,600 confirmed infections and 5,000 cases under investigation, and Michigan reporting over 2,600 cases alone . The contagious intestinal parasite, cyclospora, has sparked fears and confusion, driving consumers to social media for advice on what foods to avoid .
What Foods are Linked to Cyclosporiasis?
Cyclosporiasis has been repeatedly linked to fresh produce, particularly foods consumed raw. Foods commonly contaminated with cyclospora are raspberries, basil, cilantro, green onions, snow peas, and leafy greens like lettuce and salad mixes. These foods, often eaten uncooked, pose a significant risk due to their susceptibility to contamination.
How Does Cyclosporiasis Spread?
Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which is spread through contaminated food or water. This parasite is particularly prevalent in tropical and subtropical regions, where routine chemical disinfection or sanitization of food or water is not always effective. The parasite thrives in fecal matter, making food and water contaminated with feces a primary source of infection.
The Impact of Cyclosporiasis on Public Health
To date, no commercially frozen produce, cooked foods, or peeled fruit have been associated with cyclosporiasis infection, making these safer alternatives during an outbreak. However, the CDC has confirmed a significant increase in cases, highlighting the need for public vigilance . Consumers are advised to avoid lettuce and salad greens as the most recent outbreaks are linked to them. Additionally, berries, and water should also be avoided to prevent contamination.
