US health officials say cyclospora outbreak has ended as number of reported cases declines

(WASHINGTON) — The Centers for Disease Control and Prevention announced Friday that the cyclospora outbreak that plagued thousands of people across the country during the summer months has ended.

The outbreak, which was eventually tied to iceberg lettuce distributed by Taylor Farms, sickened almost 13,000 people in 21 states. Two people died and at least 570 people were hospitalized due to cyclospora illness.

The FDA announced in July that it was investigating cyclospora illnesses linked to shredded iceberg lettuce served at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio and West Virginia after several cases of cyclospora had been reported in late June.

The CDC said Friday more than 1,000 cases were reported in a single day at the height of the outbreak, before the contaminated lettuce was recalled by Taylor Farms on July 17. The illness notably made headlines for causing “explosive diarrhea.”

Citing a decline in infections linked to the outbreak — fewer than two per day in August — and all contaminated Taylor Farms products being taken out of circulation, the CDC said it considers this specific outbreak over. It notes the best-by dates for all products linked to the outbreak have passed and are no longer available in stores or restaurants.

The FDA will continue to investigate the cause of the contamination, which has not yet been identified.
