GAINESVILLE, Fla. — With more people buying local and organic food, consumers should know the difference between the two so they recognize what they’re buying, but nearly one in five still confuse the terms, a University of Florida researcher says.
Newly published research, done in partnership with three other universities, aims to help local and organic food producers and sellers target their marketing messages to reinforce or dispel consumers’ perceptions. The organic-food industry has spent millions of dollars building brand awareness, only to see some consumers confuse “organic” food with “local” food products, said Ben Campbell, a University of Connecticut extension economist and the study’s lead author.
Hayk Khachatryan, a UF food and resource economics assistant professor, worked with Campbell and others to survey 2,511 people online in the U.S. and Canada in 2011 and found 17 percent thought the terms were interchangeable, the study said.
K.C. Jeong, an assistant professor of animal sciences at UF/IFAS, led the study.
GAINESVILLE, Fla. — A new biological treatment could help dairy cattle stave off uterine diseases and eventually may help improve food safety for humans, a University of Florida study shows.
Kwang Cheol Jeong, an assistant professor in animal sciences and UF’s Emerging Pathogens Institute, examined cattle uterine illnesses because they can make cows infertile, lower milk production and because those maladies are often linked to bacteria, he said. The UF researchers did their experiments in labs and at the Dairy Unit on the Gainesville campus.
Jeong and his research team infused chitosan microparticles ─ an antimicrobial material derived from dissolved shrimp shells ─ into diseased cow uteri. When bought in stores, chitosan can be used to treat many ailments from obesity to anemia. On its own, chitosan only works at acidic pH levels, Jeong said. For cattle, Jeong’s team developed chitosan microparticles, which work in acidic and neutral pH, because cattle uteri have a neutral pH.

GAINESVILLE, Fla. — Food safety is near the top of most Floridians’ concerns, behind only the economy and health care, a survey released today by the University of Florida shows.
The survey covered several food-related issues, including public perceptions about food safety, food insecurity and genetically modified foods. It also found knowledge gaps among Floridians, especially in the area of food safety, and detected conflicted feelings among the public about genetically modified foods. (more …)

GAINESVILLE, Fla. — Milk may be sold in supermarkets, but it comes from cows – that’s the lesson being offered this Saturday at Family Day at the Dairy Farm, a free open-house event at the University of Florida’s dairy farm in Hague, 20 minutes northwest of Gainesville.
From 9 a.m. to 2 p.m., dairy researchers and Extension specialists with UF’s Institute of Food and Agricultural Sciences will showcase the farm’s operations and explain how their work helps commercial dairy producers. For directions, see http://tinyurl.com/d3a5626.
Visitors can watch cows being fed and milked, learn about cattle nutrition and health-care practices, pet live calves, tour barns, sample dairy products and make their own butter.

GAINESVILLE, Fla. — Last year’s open house at the University of Florida dairy farm was so successful that organizers were “moo-tivated” to repeat the event, which returns to Alachua County on Saturday, March 16.
Free and open to the public, Family Day at the Dairy Farm takes place 9 a.m. to 2 p.m. in Hague, 20 minutes northwest of Gainesville just off U.S. Highway 441. For directions, see http://tinyurl.com/d3a5626.
Visitors can watch cows being milked, pet calves, walk through free-stall barns, make butter, see farming equipment and learn how UF research helps keep dairy cows happy, healthy and productive. There will even be free samples of dairy products, a giant cow statue to admire, and a hayride to transport visitors to and from the parking area.
Local actor Houston Wells will reprise his role as President Abraham Lincoln, greeting visitors and posing for photos. It will be one of his final appearances commemorating the 150th anniversary of the Morrill Act, a bill Lincoln signed in 1862 to establish the land-grant university system. UF is the state’s flagship land-grant university.
Organizers hope to exceed last year’s attendance, which was about 800 people, said dairy Extension specialist Albert De Vries, an associate professor with UF’s animal sciences department.

GAINESVILLE, Fla. — Corn silage is an important dairy feed but it sometimes harbors an unwelcome addition – Southern corn rust, a fungal disease that thrives under hot, humid conditions.
The fungus responsible, Puccinia polysora, seems harmless to cattle. However, a Southern corn rust infection can severely reduce the yield and nutritional value of corn plants and inhibit their fermentation to silage.
Worse, it damages corn tissue, providing a gateway for opportunistic microbes such as Aspergillis. This genus of fungi includes species that produce a toxic compound called aflatoxin, which can harm or even kill cattle that eat contaminated silage. Aflatoxin can also be transmitted to the milk of cows that eat contaminated foods; in people aflatoxin can cause cancer, other diseases and death.
Now, researchers with the University of Florida’s Institute of Food and Agricultural Sciences have found a way to control negative effects of Southern corn rust on silage and prevent aflatoxin accumulation, by inoculating the silage with beneficial bacteria.
The study was published in the September issue of Journal of Dairy Science.
GAINESVILLE, Fla. — Hunting can put meat on the family table, and a University of Florida workshop is helping area men and women learn the fine points of bringing that meat home safe and ready to cook or store.
It’s called Wild Game Processing: From Field to Table, a six-hour workshop held from 9 a.m. to 3 p.m. Saturday, Sept. 29 at the UF animal sciences department, part of the Institute of Food and Agricultural Sciences.
“Proper handling and processing minimizes the risk of foodborne illness and improves the quality and storage life of wild game products for your family,” said Chad Carr, a UF meat science assistant professor. He organizes and leads the workshop, now in its second year.

GAINESVILLE, Fla. — Food-safety experts have long believed that Salmonella bacteria could only enter tomatoes through wounds in the stem or fruit — but a new University of Florida laboratory study shows it can also happen another way.
Plant pathologist Ariena van Bruggen, a professor in UF’s Institute of Food and Agricultural Sciences, published a paper today in the online journal PLoS One, with research findings that show — for the first time — that Salmonella can enter tomato plants through intact leaves, travel through the plant and end up in the fruit itself.
