First Deaths Linked to Cyclosporiasis Outbreak Reported in the US

Two people have died in the US state of Michigan as a result of a cyclosporiasis outbreak, an intestinal infection caused by a microscopic parasite. These are the first confirmed deaths in the United States linked to the disease, according to Medical Xpress, citing Michigan health officials.

The Michigan Department of Health and Human Services said both individuals had underlying medical conditions that may have been worsened by the intestinal infection and dehydration. The department said it would not release additional details about the fatalities.

The parasite, Cyclospora cayetanensis, contaminates food that has come into contact with human feces, most commonly through the use of contaminated water for irrigation or washing fruits and vegetables. Once ingested, it causes an intestinal illness characterized by frequent, and sometimes severe, episodes of diarrhea, according to the US Centers for Disease Control and Prevention (CDC).

Federal investigators have identified lettuce grown in Mexico and served at Taco Bell restaurants across five US states as the source of the large outbreak.

The outbreak is the largest ever recorded in the United States. Since May 1, the CDC has received reports of more than 4,100 confirmed cases and is investigating an additional 7,400 probable cases across 41 states.

Federal health authorities warn that, as the investigation continues, other brands, restaurants, retailers, or supply chains may also be linked to the outbreak.
