A rare outbreak in the USA: thousands infected with a food-borne parasite

A large-scale outbreak of the intestinal disease cyclosporiasis has been keeping health authorities in the United States busy in recent weeks. According to the U.S. Centers for Disease Control and Prevention (CDC), since the beginning of May, there have been reports of more than 1,600 laboratory-confirmed cases and over 5,000 additional cases under investigation, with estimates suggesting the actual number of patients is higher.

At the same time, the FDA and the CDC are conducting an extensive investigation into a suspected link between the outbreak and Iceberg Lettuce imported from Mexico. As part of the investigation, a recall was issued for certain products, but authorities emphasize that the investigation is ongoing and not all sources of infection have been identified with certainty.

What is Cyclospora?

Cyclospora is an intestinal disease caused by the parasite Cyclospora cayetanensis, which is transmitted mainly through food or water contaminated with feces. Unlike many viruses, the disease is not generally transmitted from person to person. Symptoms usually appear about a week after exposure and include prolonged diarrhea, abdominal pain, nausea, decreased appetite, fatigue, and sometimes a mild fever. Without appropriate treatment, the disease may last for weeks or even months.

Is there a reason for concern in Israel?

In Israel, no similar outbreak has been reported, but public health experts emphasize that in an era of importing agricultural produce from all over the world, food safety requires continuous monitoring. According to experts, careful washing of vegetables and fruits, maintaining kitchen hygiene, and purchasing produce from supervised sources significantly reduce the risk of food-borne infections.
