GAINESVILLE, Fla. — Can crops be fortified to improve diets and lower the rate of chronic diseases? Cathie Martin, a world-renowned expert on plant metabolic engineering, will discuss that question at the 2017 E.T. York Lecture.
The free event will be held at 2 p.m., Thursday, April 13 in the University of Florida Emerson Alumni Hall. The UF Institute of Food and Agricultural Sciences is hosting the lecture.
Martin is a group leader at the John Innes Centre in the United Kingdom, the leading plant research institute in Europe. Also, Martin is a professor at the University of East Anglia where she researches the relationship between diet and health, and how crops can be fortified to improve diets and address the problem of escalating chronic illnesses. Her work links leading clinical and epidemiological researchers with plant breeders and metabolic engineers.
GAINESVILLE, Fla. — Assistant professor Raelene Crandall walks her 18 students into Austin Cary Forest, part of the University of Florida Institute of Food and Agricultural Sciences, where they will set a fire. Crandall and the students stand out in their lemon yellow shirts, forest green pants, leather boots and gloves, and hard hats—all fireproof.
“Wildfire season is starting early this year, because we’re seeing a warmer, drier spring,” said Crandall, who teaches fire ecology in the UF/IFAS School of Forest Resources and Conservation. “Experts predict an unusually bad wildfire season this year with the dry conditions and prescribed burns may help lower that number.”
The students check the plow line, which is used to contain a fire to a particular area and then start a fire along the edge. They stand back as plants begin to burn and the fire gradually progresses. “If we don’t conduct prescribed burns, we will get larger, often catastrophic fires that threaten families and structures,” Crandall explained.
FORT LAUDERDALE, Fla. — The University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) and the Florida Fish and Wildlife Conservation Commission (FWC) are working together on unique projects to target Burmese pythons in Florida. Two projects include using detection dogs and Irula tribesmen to help remove pythons from environmentally sensitive areas.
In their first eight days on the job, the Irula tribesmen — world-renowned snake catchers from India — removed 13 pythons, including four on their first visit to Crocodile Lake National Wildlife Refuge on North Key Largo in partnership with the U.S. Fish and Wildlife Service. Traditionally, the main occupation of the Irula tribe has been catching snakes. They have successfully hunted and captured Indian pythons in their home province of Tamil Nadu.
“Since the Irula have been so successful in their homeland at removing pythons, we are hoping they can teach people in Florida some of these skills,” said Kristen Sommers, section leader of the FWC’s Wildlife Impact Management Section. “We are working with our partners to improve our ability to find and capture pythons in the wild. These projects are two of several new efforts focused on the removal of these snakes.”
GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences researchers and Extension agents are fanning across the state and the Southeast region to help growers and packers meet new federal food safety guidelines.
Driving across the state to packinghouses, farms and training centers, scientists such as Michelle Danyluk, Keith Schneider and Renee Goodrich are training growers in the latest regulations. “The state is massive, and we are not only tasked with helping Florida farmers meet new safety guidelines, but also are tasked with training educators in the Southeast so they can help growers in their states,” said Schneider, who with his colleagues is in the UF/IFAS department of food science and human nutrition.
Last fall, the U.S. Food and Drug Administration (FDA) released several major rules that comprise the new Food Safety Modernization Act (FSMA). The federal government has recognized the role of Extension specialists in training programs for key sections such as the Produce Safety Rule and the Preventive Controls for Human Foods Rule, Schneider said.
The University of Florida is one of two institutions that was awarded a $1.2 million grant by USDA in 2015 to help lead such training, Danyluk said. The Southern Training, Education, Extension, Outreach, and Technical Assistance Center to Enhance Produce Safety at UF, led by Danyluk, is one of two regional programs that play a leading role in coordinating and implementing FSMA-related training, education, and outreach programs for small and medium-sized farms, beginning farmers, socially disadvantaged farmers, small processors, and/or small fresh fruit and vegetable merchant wholesalers.
GAINESVILLE, Fla. — Global climate change has already impacted every aspect of life on Earth, from genes to entire ecosystems, according to a new study by the University of Florida Institute of Food and Agricultural Sciences and in cooperation with a broad international partner group, published in the prestigious journal Science.
“We now have evidence that, with only a ~1 degree Celsius of warming globally, major impacts are already being felt in natural systems,” said study lead author Brett Scheffers, an assistant professor in the UF/IFAS department of wildlife, ecology and conservation. “Genes are changing, species’ physiology and physical features such as body size are changing, species are shifting their ranges and we see clear signs of entire ecosystems under stress, all in response to changes in climate on land and in the ocean.”
During this research, Scheffers, a conservation ecologist, collaborated with a team of researchers from 10 countries, spread across the globe. They discovered that more than 80 percent of ecological processes that form the foundation for healthy marine, freshwater and terrestrial ecosystems already show signs of responses to climate change.
“Some people didn’t expect this level of change for decades,” said co-author James Watson, of the University of Queensland in Australia. “The impacts of climate change are being felt with no ecosystem on Earth being spared.“
GAINESVILLE, Fla. — People who know a lot about genetically modified foods are inclined to agree with the scientific consensus that such foods are safe to eat. But, those who know plenty about global warming are cautious about the science that says humans cause the phenomenon, a new University of Florida Institute of Food and Agricultural Sciences study shows.
Furthermore, the study showed some people still make what researchers call “illusionary correlations,” such as “genetically modified foods cause autism.”
Perhaps science communication should address people’s perceptions about illusionary correlations versus their knowledge of global warming and genetically modified foods, said Brandon McFadden, a UF/IFAS assistant professor of food and resource economics and author of the study. Merely providing people with information is insufficient to change behavior, McFadden said.

GAINESVILLE, Fla. — As Hurricane Matthew dumped water and wind on Florida’s east coast last week, it wasn’t long before several alligators were spotted roaming the parking lot at the University of Florida Institute of Food and Agricultural Sciences Extension Brevard County office. But alligators or no alligators, the two faculty members hunkered down in the facility weren’t about to leave their posts any time soon.
“We have a very large generator at the office that we needed to keep running during the storm in case people at the county facilities lost power and had to move to our facility,” said Linda Seals, director of UF/IFAS Extension Brevard County.
Seals’ staff weren’t the only ones hard at work helping residents and emergency personnel weather the storm. From housing evacuated livestock to manning the phones at local emergency operations centers, UF/IFAS Extension faculty across the state put in many long hours and a few sleepless nights keeping people safe and informed.
“We serve 20 million Floridians year-round in our day jobs, but in a crisis we work 24/7 to help those most in need” said Jack Payne, UF senior vice president for agriculture and natural resources. “We demonstrated all weekend long how much we value our relationships. Our actions told our communities that this isn’t just a job to us. This was about helping friends, neighbors and community members.”
GAINESVILLE, Fla. — University of Florida Institute of Food and Agricultural Sciences Extension is working closely with Florida’s emergency operation centers to provide emergency information and assistance to those in the path of Hurricane Matthew.
“The local UF/IFAS Extension office is a disaster response resource in every community in Florida,” said Angie Lindsey, assistant professor of family, youth and community sciences. Lindsey is the UF/IFAS point of contact for the Extension Disaster Education Network (EDEN), a national organization of Extension educators who work to prepare communities for disasters.
Lindsey, who works with the UF/IFAS Center for Public Issues Education in Agriculture and Natural Resources, helps UF/IFAS Extension agents develop disaster response tools and further collaboration between agents and local officials.

GAINESVILLE, Fla. — A team of scientists led by University of Florida Institute of Food and Agricultural Sciences researchers has found a faster and more precise way to detect salmonella in beef and chicken, a finding that could help prevent major illnesses.
Salmonella is the lauding cause of bacteria-associated foodborne illnesses in the United States, according to the study. Thus, early detection of the pathogen, by a rapid and sensitive test is important to prevent the illness.
In a newly published study, researchers artificially contaminated food with salmonella. They then tested the food samples using Salmonella-specific antibodies combined with a unique signal amplification technique. Their test found salmonella present after 15 hours and removed other microorganisms that sometimes clutter laboratory results. This is shorter than the two to three days it takes to detect salmonella in a culture, the study shows.

GAINESVILLE, Fla. — Florida beekeepers are concerned after 2.5 million bees that were killed during an aerial spraying with Naled/Dibrom for Zika-carrying mosquitoes in Dorchester County, S.C. Now, Floridians are looking for ways to avoid the same tragedy. Florida is the third-largest beekeeping state in the nation.
Researchers are not surprised that the South Carolina incident has Florida beekeepers worried, said Fred Fishel, professor of agronomy and director of the Pesticide Information Office.
“With the Zika cases in south Florida, and now that scientists have identified mosquitoes that carry the Zika virus, we would expect beekeepers to be concerned about increased pesticide application,” Fishel said. “But, registered beekeepers should be notified before an application of pesticides. That gives them time to protect their bees while spraying is conducted.”
There are pesticides that will not harm bees, but will kill mosquitoes, says William Kern, associate professor of urban entomology at the UF/IFAS Fort Lauderdale Research and Education Center.
