First two deaths linked to cyclospora outbreak reported in US

Michigan health officials have confirmed the first two deaths linked to the ongoing cyclospora outbreak, a parasitic infection spread through contaminated food or water that can cause severe diarrhoea. The two individuals had significant underlying health conditions that may have been worsened by cyclosporiasis and dehydration, according to state health authorities.

The foodborne illness has spread to 45 states, with nearly 7,000 laboratory-confirmed cases reported nationwide, according to the US Centers for Disease Control and Prevention (CDC). Although thousands have been infected, the CDC notes that deaths from cyclosporiasis are uncommon, as the illness is "not usually life-threatening." Michigan’s health department declined to provide further details about the deceased. The state is the current epicentre, with more than 11,000 cases and 193 hospitalisations on record, although many have not been laboratory-confirmed.

The heat-loving parasite infects the intestines and is transmitted through faecal contamination. Past outbreaks have been linked to fruits and vegetables irrigated with water contaminated by faeces.

The CDC recommends washing all produce under running water, including items labelled as pre-washed. However, washing alone may not fully remove the parasite. Cooking produce to at least 70°C (158°F) is advised to kill it.

Officials have linked this year’s widespread outbreak to lettuce imported from Taylor Farms in Mexico, a major supplier for many US food establishments. Taco Bell has removed the supplier’s lettuce from its menu, and Taylor Farms has issued a voluntary recall of lettuce sourced from central Mexico.

UK health officials have also warned about the outbreak following recent cases among returning travellers.
