The White House announced on July 16, 2026, that it is monitoring a multistate outbreak of a parasite that has sickened more than 400 individuals. Press Secretary Karoline Leavitt stated that the administration is collaborating with the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) to trace the outbreak's source. Leavitt emphasized that the agencies have the necessary resources to address the situation despite concerns regarding staffing changes.
The CDC is investigating the outbreak, which has been reported in Michigan, Ohio, Kentucky, and West Virginia. The agency noted that the actual number of cases may be higher, as many infected individuals do not seek medical attention. The outbreak appears to have intensified since May, and health officials are conducting patient interviews and reviewing food supply records to identify the contaminated food item.
While no specific food has been linked to the outbreak yet, cyclospora infections are often associated with fresh produce such as leafy greens, herbs, and berries. Symptoms of cyclospora infection typically begin about a week after exposure and may include prolonged watery diarrhea, fatigue, and stomach cramps. The CDC advises consumers to wash fresh produce thoroughly, cook food when possible, and stay hydrated if symptoms develop. It also recommends that patients specifically request testing for cyclospora, as routine stool tests may not screen for the parasite.
