Foodborne illness investigations are unfolding in several parts of the US, with health agencies warning that fresh produce can sometimes carry parasites that are hard to spot. The current concern is Cyclospora, a stomach parasite the CDC says can spread through contaminated food or water and cause days or even weeks of diarrhea.
What health officials have confirmed so far
The CDC has said Cyclospora infections are being reported in multiple US states, and the illness is tied to a microscopic parasite called Cyclospora cayetanensis. According to the agency, people usually get sick after swallowing food or water contaminated with the parasite, and symptoms can include watery diarrhea, stomach cramps, nausea, and fatigue.
The CDC has also said symptoms often start about 1 week after exposure. Some people may also have bloating, increased gas, or weight loss, according to federal health guidance. Not every patient gets every symptom, but diarrhea lasting several days is one of the most common signs health officials track.
No single nationwide source has been publicly confirmed in the material provided here. Health agencies have not released a full list of every affected state or every food item under review in this prompt, so that remains unclear.
What this means in states across the country
For people in any state, the practical risk is tied less to geography and more to what they eat and drink, because Cyclospora can spread through imported or domestically distributed produce. The CDC says outbreaks in the US have often been linked to fresh items such as cilantro, basil, raspberries, snow peas, and bagged salad mixes.
Unlike some other germs, Cyclospora does not usually spread directly from one person to another because the parasite needs days to weeks in the environment before it becomes infectious, according to the CDC. That means food and water exposure remain the main concern in multi-state investigations.
What is not yet known from the information provided is whether one brand, one grower, or one distribution chain is responsible for the current outbreak. Officials also have not publicly identified a complete state-by-state location list in this prompt.
How to lower your risk right now
The CDC says washing your hands with soap and water before eating, after using the bathroom, and before handling food can reduce exposure to many foodborne illnesses. Health officials also recommend rinsing fresh produce under running water before eating, cutting, or cooking it, even though washing may not remove every trace of Cyclospora.
The parasite can be difficult to kill with routine produce washing alone, according to CDC guidance, which is why knowing about recalls or outbreak advisories matters when officials identify a source. People with symptoms that last more than a few days may need medical care, since Cyclospora infection is treatable with prescription medication.
Federal health guidance says anyone with prolonged diarrhea should pay attention to dehydration, especially children, older adults, and people with weakened immune systems. As of July 14, 2026, the key public message remains simple: follow food safety basics and watch for official updates as investigators work to identify confirmed sources.
