Health authorities in the United States are currently probing a potential link between fresh produce and a surge in cyclosporiasis cases, a parasitic infection that can lead to diarrhea and other gastrointestinal issues. As of July 13, the Centers for Disease Control and Prevention (CDC) reported over 1,600 confirmed cases, with an additional 5,000 infections under investigation. Data from various states indicates that the actual number of cases could be significantly higher. In Michigan alone, health officials are monitoring more than 2,600 infections, as stated by the state's Department of Health and Human Services.

The illness is caused by the Cyclospora cayetanensis parasite, which is generally transmitted through contaminated food or water. Although the CDC has yet to pinpoint the source of the recent uptick in cases, they have indicated that not all reported infections are connected to a single outbreak across multiple states. In Michigan, officials are particularly examining whether lettuce might be the cause of the outbreak, while keeping other food items as potential sources.

Infection typically occurs after consuming food or water tainted with fecal matter, according to the CDC. Previous outbreaks of cyclosporiasis have been associated with various fresh produce items.

The Michigan Department of Health and Human Services, along with the Outbreak Database, has identified several foods linked to earlier outbreaks in the U.S. and Canada, including:

• Bagged salad mixes and kits


• Basil


• Blackberries


• Carrots and celery


• Cilantro


• Green onions


• Green peas


• Leaf lettuce


• Parsley


• Onions


• Raspberries


• Romaine lettuce


• Snow peas


• Strawberries


• Tomato salad


• Zucchini

Officials have not confirmed whether any of these items are responsible for the current rise in cases.

Expert Opinions

Dr. Rabia de Latour, a gastroenterologist at NYU Langone, advised USA Today that she is currently avoiding certain fresh produce until the source of the outbreak is determined. She specifically mentioned steering clear of bagged lettuce, cilantro, parsley, and raspberries, while noting that fruits with protective skins, like bananas, oranges, and kiwis, are safe to consume if washed properly. "We have to provide general advice at this point because the source remains unknown," she stated. Dr. de Latour emphasized that while cyclosporiasis is treatable and rarely fatal, it can pose serious health risks for immunocompromised individuals or those with other vulnerabilities.
