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

August 3, 2026

Michigan health officials have reported the first two fatalities associated with an ongoing cyclospora outbreak affecting the United States, though both victims had serious pre-existing medical conditions. The parasitic infection, which spreads through contaminated food or water and causes severe intestinal illness, has reached 45 states with approximately 7,000 confirmed cases nationwide. Authorities have traced the outbreak to contaminated lettuce imported from Taylor Farms' Mexican operations, prompting voluntary recalls and menu changes at restaurants like Taco Bell.

Who is affected

  • Two deceased individuals in Michigan with underlying health conditions
  • Nearly 7,000 people nationwide with laboratory-confirmed cyclospora infections
  • More than 11,000 affected individuals in Michigan (including non-laboratory-confirmed cases)
  • 193 hospitalized patients in Michigan
  • Taco Bell customers and patrons of food establishments supplied by Taylor Farms
  • UK travelers returning from affected areas
  • Taylor Farms (lettuce supplier from Mexico)

What action is being taken

  • Michigan health authorities are investigating the deaths
  • The CDC is tracking and reporting cases nationwide
  • Taco Bell has removed lettuce from the implicated supplier from its menu
  • Taylor Farms is conducting a voluntary recall of lettuce sourced from central Mexico
  • UK health officials are warning about the outbreak

Why it matters

  • This outbreak represents a significant public health concern because it has spread to 45 states with thousands of infections, demonstrating how contaminated produce from a single supplier can affect the entire nation's food system. The deaths, while rare for this type of infection, highlight the serious risk that cyclosporiasis poses to vulnerable populations with underlying health conditions, particularly when combined with dehydration. The outbreak underscores critical food safety issues in the agricultural supply chain, specifically regarding irrigation water quality in imported produce, and serves as a reminder of the importance of proper food handling and preparation to prevent foodborne illness.
