Sept 3 (Reuters) – Michigan health officials reported 14,718 cases linked to an outbreak of cyclosporiasis on Thursday, an increase of 208 cases since its ​last update a week earlier.

Here are some ‌details:

• The outbreak in Michigan has resulted in 366 hospitalizations as of September 3, according to state health department’s latest update.

• The cyclosporiasis outbreak is among the largest foodborne illness events ‌in ​recent U.S. history and has shaken ⁠U.S. consumer confidence around ⁠fresh produce.

• Michigan has been the hardest hit, and reported two related deaths last month, both in people with significant underlying health conditions.

• 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 18,445 laboratory-confirmed cases ‌of cyclosporiasis acquired in the United States as of Tuesday.

• An FDA investigation has linked the multistate outbreak that has expanded to 20 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.

• Taylor Farms recalled ⁠all iceberg lettuce sourced from central Mexico ​on ‌July 17, and the company has temporarily ​suspended operations ⁠at its processing facility there, though it was later ruled a false positive.

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