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 impacted by cyclosporiasis and dehydration”, the BBC reported, citing state health authorities.

Why are the deaths considered unusual?
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). While the outbreak has infected thousands of people, deaths from cyclosporiasis are far from common. The CDC says the illness is “not usually life-threatening”.
Why is Michigan at the epicentre?
Michigan is at the epicentre of the current outbreak, with state records showing more than 11,000 cases and 193 hospitalisations, although many have not been confirmed through laboratory testing.
The heat-loving parasite infects the intestines and is transmitted through faecal contamination. Past outbreaks have occurred after people consumed fruits or vegetables irrigated with water contaminated by faeces.
Can washing produce prevent infection?
The CDC recommends washing all produce under running water, including items labelled as pre-washed.
Washing alone, however, might not be enough to remove the parasite. The agency recommends cooking produce to a temperature of at least 70°C, or 158°F, which can kill the parasite.
How is lettuce linked to the outbreak?
Officials have linked this year’s widespread outbreak to lettuce imported from Taylor Farms in Mexico, a key supplier to many food establishments in the US. US fast-food chain Taco Bell said it has removed lettuce supplied by Taylor Farms from its menu. Taylor Farms announced a voluntary recall of lettuce sourced from central Mexico.
UK health officials have also warned about the outbreak following recent cases contracted by returning travellers.
