US reports first two deaths linked to 'explosive diarrhoea' outbreak

The Centers for Disease Control and Prevention (CDC) in the United States has reported the first two deaths associated with the ongoing cyclospora outbreak, a parasitic infection caused by contaminated food or water that leads to severe diarrhoea. The individuals who succumbed to the illness were found to have underlying health conditions that may have exacerbated the impact of cyclosporiasis and dehydration, according to state health authorities.

The cyclospora infection has proliferated across 45 states in the US, with nearly 7,000 laboratory-confirmed cases reported nationwide, as per the CDC. While the outbreak has affected thousands, the CDC emphasizes that deaths from cyclosporiasis are rare, as it is typically not life-threatening.

Michigan's health department has not disclosed further details about the deceased. The state is currently at the heart of the outbreak, with over 11,000 cases and 193 hospitalizations recorded, though many cases remain unconfirmed through laboratory testing. The cyclospora parasite, which thrives in heat, infects the intestines and spreads via faecal contamination. Past outbreaks have occurred when people consumed fruits or vegetables irrigated with contaminated water.

The CDC advises washing all produce thoroughly under running water, even those labeled pre-washed, as washing alone may not eliminate the parasite. Cooking produce to a temperature of at least 70°C (158 °F) can effectively kill the parasite, the agency recommends. This year's widespread outbreak is believed to be linked to lettuce imported from Taylor Farms in Mexico, a primary supplier for numerous food establishments in the US.

Taco Bell has taken immediate action by removing lettuce from the affected supplier from its menu. Taylor Farms has also voluntarily recalled lettuce sourced from central Mexico. The UK health authorities have also issued warnings regarding the outbreak following recent cases contracted by individuals who had recently returned from travel.
