The Outbreak


Michigan has confirmed its first two fatalities linked to the ongoing cyclospora outbreak, a parasitic infection that can cause severe diarrhoea.


The victims had significant underlying health conditions that may have been impacted by cyclospora infection and dehydration, according to the state health department.


Across the United States, the outbreak has reached 45 states, with nearly 7,000 laboratory‑confirmed cases nationwide and thousands of people already ill.


While cyclospora generally is not life‑threatening, deaths are exceptional and usually occur in individuals with pre‑existing conditions or who experience acute dehydration.


Michigan is the epicentre of this year's outbreak, reporting more than 11,000 cases and 193 hospitalisations, although many have not been lab‑confirmed.


The parasite thrives in warm environments and spreads through faecal contamination, often via produce irrigated with contaminated water.


Past outbreaks have been linked to consumption of lettuce, spinach or other leafy greens that were irrigated with contaminated source water.


The CDC recommends rinsing all produce under running water, and cooking produce to a minimum temperature of 70°C (158°F) to eliminate the parasite.


Officials attribute this year's widespread outbreak to lettuce sourced from Taylor Farms in Mexico, a key supplier for many U.S. restaurants. Taylor Farms has voluntarily recalled lettuce from central Mexico, and Taco Bell has removed the affected product from its menu.


UK health authorities have also issued warnings after cases were contracted by returning travellers.
