GAINESVILLE, Fla. — University of Florida researchers have gained new insight into produce-associated salmonella that they hope will eventually reduce the number and severity of the illness-causing outbreaks.
Tomato variety and weather can combine to make what the researchers call a “perfect storm” for salmonella to proliferate in harvested tomatoes, a new study shows.
It remains unclear how much each contributes to salmonella’s spread, but scientists say understanding the process is key to eventually curbing produce-associated outbreaks.
GAINESVILLE, Fla. – Two papers co-authored by a University of Florida professor have been highlighted by a leading science journal.
The science journal Plant Physiology recently named the studies “Crop Genome Plasticity and Its Relevance to Food and Feed Safety of Genetically Engineered Breeding Stacks” and “Evaluating the Potential for Adverse Interactions within Genetically Engineered Breeding Stacks” as Editor’s Choice papers.
The papers were co-authored by Curtis Hannah, an professor with the horticultural sciences department, part of the UF Institute of Food and Agricultural Sciences.
GAINESVILLE, Fla. — To the owner, a tract of timberland may be a wise investment or a family legacy. Unfortunately, to others that same acreage may look like a great place to cook methamphetamine, poach deer or steal a few truckloads of logs.
To help North Florida residents prevent illegal activity on their land, the University of Florida’s Institute of Food and Agricultural Sciences has joined forces with Florida’s Forest Stewardship Program and state agencies to present a one-day workshop, called Timberland Security for Owners.
It happens 9 a.m. to 2 p.m. Thursday, Feb. 7 at the UF/IFAS Columbia County Extension Office in Lake City.
“We have a great program that’s dynamic and interesting, and covers material that every forest landowner should know for their own protection and protection of the community,” said Chris Demers, Forest Stewardship Program coordinator in Gainesville.
GAINESVILLE, Fla. — The quest to develop a grapefruit hybrid that will not interact with medication has taken a step forward, as researchers pinpoint compounds most responsible for the problem, a University of Florida citrus breeder says.
The data were published in the December 2012 issue of the journal Xenobiotica.
Scientists have been aware of the so-called “grapefruit juice effect” since 1989. Compounds in the fruit called furanocoumarins inhibit the action of an enzyme that breaks down certain medications in the human digestive system.
The phenomenon poses a health risk because it can produce unexpectedly high levels of these medications in a patient’s bloodstream. Doctors, pharmacists and prescription drug labels warn patients to avoid grapefruit and related products under these circumstances.

GAINESVILLE, Fla. — As a carrier of as many as 100 types of germs, the common house fly is hardly as innocuous as its name might suggest.
Military personnel know this firsthand, and their need for effective fly control has helped University of Florida researchers create an innovative new fly control device.
Known as the Florida Fly-Baiter, the device is blue — in contrast to the yellow fly control devices on the market — and is far more effective, said Phil Koehler, a professor of urban entomology with UF’s Institute of Food and Agricultural Sciences.

GAINESVILLE, Fla. — Mosquitoes aren’t just a nuisance, they’re also an economic and health concern, say University of Florida researchers.
July, August, and September are peak months for mosquito activity in Florida, and the state spends about $151 million each year trying to control the biting insects.
Controlling mosquitoes is important for economic development and tourism, said Jonathan Day, a University of Florida medical entomology professor at UF’s Florida Medical Entomology Lab in Vero Beach.

GAINESVILLE, Fla. — New findings by the University of Florida may help lead to a cure for a deadly disease that primarily afflicts premature newborns.
Necrotizing enterocolitis, or NEC, is the death of tissue in the bowels that causes inflammation, abdominal distention, bleeding, and in about 25 percent of the cases, mortality. It most often occurs in newborns during the first weeks of life.
Current treatments for NEC depend on the severity and include surgical and non-surgical techniques. Medical care for infants with NEC is estimated to cost up to $1 billion each year in the United States.

GAINESVILLE, Fla. — University of Florida researchers have discovered that tomato variety and maturity influence the ways salmonella bacteria respond to the fruit.
The findings, published Aug. 31 by the online, open-access journal Public Library of Science (PLoS) ONE, suggest researchers may be able to develop tomato cultivars more resistant to salmonella contamination.
Also, by monitoring tomato ripeness, it may be possible to reduce fruit’s susceptibility to contamination during and after harvest, said Max Teplitski, an associate professor in soil microbiology. (more …)
The University of Florida Office of Sustainability will host the first Florida Food Summit April 12-13. The event at UF’s Reitz Student Union will facilitate networking, dialogue and visioning among members of the Florida food system. The summit will help develop the connections needed for robust farm-to-institution programs and is part of the Office of Sustainability’s “40 Days of Change” campaign – a celebration of the 40th anniversary of Earth Day.
The event will begin with a welcome reception, followed by discussion panels focusing on local food systems at the local and state level. Other events include film screenings, multimedia presentations, a “Food on the Lawn” fair and farmers market.
“Food on the Lawn” will take place on UF’s Plaza of the Americas from 11 a.m. to 3 p.m. April 12, featuring food demonstrations, educational displays and local produce for sale. A photography exhibition, “Range, Furrow, and Grove: Images of Florida Agriculture,” will also be on display April 5-17 in the Reitz Student Union Gallery. (more …)

GAINESVILLE, Fla. — When it comes to fighting fires, it’s usually the guy with the hose that gets all the hero worship. But as ever-increasing temperatures and droughts bring a greater threat from wildfires, sometimes it’s the guy with a torch who can do the most good.
“Fire is an art,” said Parker Titus, a specialist with more than 400 controlled burns on his resume. “It’s one of the most powerful influences on our natural systems. Knowing how to use it — and not let it get out of control — is an essential part of the conservation effort.”
This week, Titus and his crew, the newly formed Northeast Florida Resource Management Support Team, will be sharing that knowledge with 40 students and public agency employees.
The team will help teach how to stay safe while practicing controlled burns as part of a weeklong basic wildland firefighter training program conducted by the University of Florida, The Nature Conservancy and the Natural Areas Training Academy.
