Aug 5 (Reuters) – Michigan health officials reported 12,218 cases linked to an outbreak of cyclosporiasis on Wednesday, an increase of 710 cases since its last update ​a day earlier.

Michigan has reported the first two ‌deaths associated with the outbreak, saying both individuals had significant underlying health conditions.

Here are some details:

• The state said the two Michigan cases became ill prior to the voluntary recall of iceberg lettuce ‌announced ​by the U.S. Food and Drug ⁠Administration on July 17.

• The ⁠outbreak in Michigan has resulted in 193 hospitalizations as of July 30, according to the state health department’s latest update.

• Cases of the intestinal infection caused by ​the cyclospora parasite, which can cause diarrhea, nausea and other gastrointestinal symptoms, have risen steadily across the United ⁠States in recent months, according to ⁠the U.S. Centers for Disease Control and Prevention.

• ​Nationwide, the CDC has received reports of 10,468 laboratory-confirmed domestic ​cases of cyclosporiasis and is aware of more ‌than 12,255 additional cases that are not laboratory-confirmed.

• The agency’s surveillance lags state reporting by several weeks.

• An FDA investigation has linked the multistate outbreak that has expanded to ⁠nine states to iceberg lettuce served at Taco Bell restaurants and sourced from privately held Taylor Farms operations in central Mexico, but ⁠authorities are still ‌looking for other potential sources.

• Consumers in ⁠the U.S. have been steering clear of ​some ‌restaurant chains and buying less lettuce in ​grocery stores, ⁠as a multistate outbreak of a parasitic disease has fueled confusion over what is safe to eat.

• Cyclosporiasis can be contracted by consuming food — typically raw fruits and vegetables — or water contaminated with feces.
