WASHINGTON, D.C. – Health officials are urging extra caution with fresh food platters this holiday weekend as an explosive, diarrhea-causing parasite triggers a massive summer surge in food poisoning cases just before Independence Day.
The Summer Surge
According to the Centers for Disease Control and Prevention (CDC) and state health data, Cyclosporiasis—a stomach-churning illness caused by the Cyclospora parasite—has sickened hundreds of people across more than 17 U.S. states since May 1.
While the CDC and FDA are actively searching for a common link, officials state this currently appears to be a severe seasonal surge rather than a single, unified outbreak.
Michigan Facing Major Cluster
The impact is heavily felt at the state level, particularly in Michigan, which is currently contending with a massive spike. State health officials reported more than 170 cases—already tripling the state’s entire total from the previous year.
According to CDC data, at least 20 people have been hospitalized nationwide, with cases affecting individuals ranging from ages 5 to 86.
Recognizing the Symptoms
The parasite is typically contracted through contaminated, unwashed summer produce like basil, raspberries, and lettuce. Symptoms usually appear about a week after exposure and include:
- Watery, frequent, and “explosive” diarrhea
- Severe stomach cramps, bloating, and gas
- Extreme fatigue and nausea
- Fever and vomiting
If left untreated, the illness can last for months and cyclically recur. Children, the elderly, and individuals with compromised immune systems are at the highest risk for severe complications.
How To Stay Safe This Holiday Weekend
To protect your family and guests during Fourth of July picnics, health departments recommend following these strict food safety steps:
- Wash Thoroughly: Wash all fresh fruits and vegetables under running water, and scrub produce with thick skins (like melons and cucumbers) before cutting.
- Sanitize Surfaces: Wash hands, utensils, and cutting boards with soap and water before and after prepping food.
- Refrigerate Fast: Place all cut or prepared fruits and vegetables in the refrigerator within two hours of preparation.
- Avoid Raw Water: Do not drink or cook with untreated water sources.
