WEST PALM BEACH, Fla. (CBS12) — The number of reported cyclosporiasis cases continues to rise across the country and in Florida.

The Centers for Disease Control and Prevention said 13,895 laboratory-confirmed, domestically acquired cases were reported from May 1 through Aug. 10. At least 740 people have been hospitalized and two have died, with cases reported in 47 states, the District of Columbia and Puerto Rico.

That is up 3,427 cases from CBS12 News’ Aug. 5 update, when the CDC was reporting 10,468 cases, 517 hospitalizations and two deaths.

Florida Department of Health data shows 417 confirmed or probable cases were reported from Jan. 1 through Aug. 8, up from 168 cases reported through July 17.

The latest county totals include 56 cases in Miami-Dade, 35 in Lee, 34 in Broward, 29 in Orange and 23 in Palm Beach.

On the Treasure Coast, St. Lucie County has three cases, Martin County has two and Indian River County has one. Okeechobee County was not listed among counties reporting cases.

The CDC’s separate National Notifiable Diseases Surveillance System reported 352 Florida cases through Aug. 1, compared with 108 at the same point in 2025. The CDC and Florida totals differ because the agencies use different reporting criteria and update schedules.

Federal investigators have also linked 9,481 illnesses in 17 states to an outbreak associated with iceberg lettuce from Taylor Farms de Mexico. That outbreak has resulted in at least 398 hospitalizations and two deaths, both in Michigan.

Lettuce outbreak now linked to more than 9,000 illnesses

Federal investigators have also substantially expanded the number of cases tied specifically to an outbreak linked to iceberg lettuce from Taylor Farms de Mexico.

As of Aug. 13, the CDC said 9,481 illnesses in 17 states had been linked to the outbreak, with at least 398 hospitalizations and two deaths. Both deaths were reported in Michigan.

That outbreak alone has grown by more than 3,100 cases since the CDC’s Aug. 5 update, when 6,358 illnesses in 15 states were associated with the lettuce.

Epidemiologic and traceback evidence showed processed iceberg lettuce from Taylor Farms de Mexico was contaminated with Cyclospora, according to the CDC. The outbreak includes people who reported eating or purchasing the lettuce at various locations, including some who previously reported eating at Taco Bell.

Taylor Farms recalled all iceberg lettuce sourced from central Mexico on July 17. The recalled lettuce was distributed to consumers, restaurants and retailers in at least 31 states, including some Taco Bell locations and Marketside-brand products sold at select Walmart stores. Federal health officials say the products’ best-by dates have passed and they should no longer be available for sale.

The CDC is also investigating other clusters and individual cyclosporiasis cases that are unrelated to the lettuce outbreak.

The latest figures mark a sharp increase from earlier this summer. On July 3, CBS12 reported 145 domestically acquired cases nationwide. By July 16, that number had risen to 1,645. On Aug. 5, the CDC reported 10,468 cases.

Cyclospora is a microscopic parasite that can cause cyclosporiasis, a gastrointestinal illness most commonly associated with frequent, watery diarrhea. Other symptoms can include cramping, bloating, nausea, fatigue, loss of appetite and weight loss. Symptoms generally begin about a week after infection but can take two weeks or longer to appear.

The CDC advises people experiencing symptoms to contact a health care provider and ask about Cyclospora testing because routine stool tests do not always screen for the parasite.
