Florida preacher Tommie Zito discusses his mission to transform the abandoned Green Mountain College in Vermont into “Z University,” a Christian college. Zito’s goal is to train future leaders in evangelism, business, government, and music. He plans for the college to be fully operational by August 2027, emphasizing the need for godly institutions to counter current educational trends.

TALLAHASSEE, Fla. – A parasite that causes extreme diarrhea, seen in recent outbreaks across the country, has been documented in over 20 counties in Florida. But experts say there could be more cases than what has been reported.

According to the Florida Department of Health’s Reportable Diseases Frequency Report, 50 cases of cyclosporiasis have been reported in the state since May 1.

“This infectious disease may be hard to monitor due to the nature of the signs and symptoms,” said Dr. Norman Beatty, an associate professor of medicine and hospital epidemiologist at UF Health Shands. “It’s common to get a diarrheal illness at times, and other infectious diseases can resolve on their own, but cyclosporiasis is important to identify right now because there are multiple outbreaks across the country.”

Cyclosporiasis is a gastrointestinal disease caused by the parasite cyclospora, which causes diarrhea, abdominal pain, nausea, fatigue and loss of appetite, according to the U.S. Centers for Disease Control.

Once a case is confirmed through testing, a report is sent to the state department of health. But if someone doesn’t seek medical attention, the case could go unreported, Beatty said.

There could be a six-week reporting lag between illness onset and reporting, according to the CDC.

Since May 1, the federal agency has received reports of 1,645 confirmed domestic cases of cyclosporiasis but is aware of more than 5,100 cases that require further analysis, the CDC stated Tuesday.

In Florida since May 1, DOH data shows Lee County has seen the most cyclosporiasis cases with nine, followed by Miami-Dade with six and Broward with five.

Other counties with cases include: Alachua, Brevard, Collier, Columbia, Duval, Escambia, Flagler, Gadsden, Highlands, Hillsborough, Lake, Orange, Osceola, Palm Beach, Pasco, Pinellas, Polk, Seminole, St. Johns, Sumter and Volusia.

In Alachua County, Beatty said he has seen several cases at UF Health Shands, which doctors believe stemmed from eating produce.

Previous outbreaks in the U.S. have been linked to raw produce, like lettuce and raspberries.

According to DOH data, Alachua County has seen one case of cyclosporiasis in June. But the department’s data is 10 days out of date, according to DOH’s website. The last day cases were uploaded to the report was July 4. And the U.S. Centers for Disease Control’s data on Florida undercounts DOH’s data, with only 11-30 reported sick people in the state.

In most scenarios, people who get cyclosporiasis will recover on their own. But in some cases, people can have persistent symptoms and relapsing infections over time, so any suspected cases should be tested, Beatty said.

Direct human-to-human transmission is rare, he said, but if infected, people could shed the parasite into the environment, where it could become infectious again within a week or two, contributing to another outbreak.

“It’s a very hardy parasite,” he said.

The outbreak was first reported in Michigan on July 1, with other outbreaks later reported in Ohio, West Virginia and Kentucky, according to the CDC.

While 34 states, including Florida, have reported cases, the source of the outbreak is still unknown.

The trail started in the early 1500s when the Spanish would drop off cattle in Fort Pierce on the east coast and drive them across the state to the Manatee River on the west coast for shipping.

• The Florida Cracker Trail is a historic cattle-driving route across the state that predates the United States.
• Florida’s early cattlemen were called “Crackers” because of the cracking sound made by their long leather whips.
• An annual cross-state ride is held to honor the trail’s history and the endurance of the original cattlemen.

The Florida Cracker Trail is older than America.

It started in the early 1500s when Spain owned Florida. The Spanish would drop off Andalusian cattle in what’s now Fort Pierce on the east coast, drive them across the state to the Manatee River on the west coast, then put the cattle on a barge and take them to Mexico.

The 146-mile trail was the only dry route across the state to move cattle, said Mike Harrison president of the Florida Cracker Trail Association.

The Kissimmee River and its floodplains were to the north, and Lake Okeechobee and the Everglades were to the south.

“Florida was the first state to have cattle drives and the last state to have cattle drives” Harrison said. “They’ve been using the same route for over 500 years.”

The Florida Cracker Association paraded through downtown Fort Pierce

Hundreds gathered to watch the annual Florida Cracker Trail Ride from Bradenton and ending in downtown Fort Pierce on Saturday, Feb. 25, 2023.

When Florida became part of the United States in 1821, the wild cattle left behind by the Spanish roamed free. Florida officially became the 27th state in 1845.

Early settlers would have wild cow hunts using the trail, except for the Manatee River. Instead, they would take cattle to Punta Rassa in Southwest Florida near Sanibel Island to ship to Cuba.

“Every group of people, every color — the Seminoles, the Black people, the freed slaves — all of them at one point were collecting these wild cows and making money off them in Florida,” Harrison said.

They were called cowmen or cattlemen — never cowboys like out West — because they had to hunt the cows on horseback in the Florida swamps, he said.

They became known as Florida Crackers because they used long bullwhips between 10 and 12 feet long made of braided leather.

“The cows would get bogged down in the wetlands,” Harrison said, “and the Crackers would use the whips to keep them moving.”

The snaps of their whips would break the sound barrier and create tiny sonic booms that could be heard for miles, he said, making a loud crack.

“People knew that the Crackers were coming,” Harrison said.

Re-enacting that rough ride annually

Every year, typically in February when the weather is cooler, Harrison is part of a group of riders who honor the history of the Cracker Trail with a cross-state ride.

From west to east, the trail follows State Road 64, or Bradenton-Arcadia Road, to a small part of U.S. 17, then County Road 66 to U.S. 98 to County Road 68, then a small part of U.S. 441 before back to C.R. 68, which is Orange Avenue, into downtown Fort Pierce.

It attracts between 60 and 200 riders each year, Harrison said, depending on the weather and the economy, especially gas prices.

The riders camp for over a week on a different ranch each night across the state, ending with a Saturday parade into downtown Fort Pierce.

“It is not a pleasure ride — it is an endurance ride,” Harrison said. “It’s grueling.”

The ranches have changed over the years and so has the route. The original 146-mile trail is now shortened to about 120 miles starting east of Bradenton because of development, he said.

But they still move slow like the Crackers who didn’t want to overwork the fat cows, going at a grazing speed of about 3 mph across the state.

“When you go on horseback, you’re going to see everything, and you get to really enjoy Florida,” Harrison said. “Now you see a lot more asphalt than you used to, a lot more houses, but there’s still some great ranches.”

‘Keep some agricultural history alive’

The Florida Cracker Trail Association formed in 1987 and started the annual cross-state ride the following year.

Harrison, who’s been president of the association for over eight years, is the second-longest-running member of the organization at over 35 years.

“We wanted to keep some agricultural history alive,” Harrison said. “We wanted people to remember the Florida Cracker Trail was a route that was used to get Florida on the map. It was the economic development of cattle and this agriculture corridor that brought success to Florida.”

The Florida Cracker Trail was selected as a Community Millennium Trail in 2000, according to its website. Millennium Trails was a partnership between the White House Millennium Council, the Department of Transportation, Rails-to-Trails Conservancy, the National Endowment for the Arts and other public agencies and private organizations.

The goal was to create of a nation-wide network of trails that protect natural environment, interpret history and culture, and enhance alternative transportation, recreation and tourism.

The Cracker Trail Museum is on the actual trail in Zolfo Springs, according to its website. The Hardee County museum is open 8 a.m. to 5 p.m. from Monday to Friday, but it’s closed for lunch.

The historic Cracker Trail is a reminder of how Florida got its economic start before America was born, Harrison said.

“We knew the development would come, so we wanted people to remember this little corridor,” Harrison said. “These rural communities that we go through, they’re there because of agriculture, not because of Disneyland.”
