Sadhana Ravishankar, associate professor at the University of Arizona’s School of Animal and Comparative Biomedical Sciences, led a team of researchers at the University of Arizona that discovered natural methods to sanitize leafy vegetables.
Food safety is a top priority for consumers, especially when it comes to the leafy greens in salads. Researchers at the University of Arizona have discovered natural methods to sanitize these vegetables using ingredients commonly found in the kitchen, such as oregano, cinnamon, and vinegar.
Plant extracts, essential oils, and organic sanitizers have all proved effective in killing bacteria on leafy greens and extending their shelf life. When emulsified in the water used to wash these leaves, the approach compares to (and sometimes even works better than) bleach or hydrogen peroxide. Read more »
David Fairchild was instrumental in establishing gardens nationwide to screen plants from overseas with potential for improving U.S. diets, gardens, and landscapes. ARS photo by Keith Weller.
This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.
Bountiful harvests don’t magically appear on store shelves and supermarkets. USDA scientists strive to make sure that the variety of meats, fruits, vegetables and grains we enjoy are hardy enough to withstand insects, diseases, droughts and other natural threats familiar to anyone with a garden or farm.
David Fairchild, a USDA scientist, was a key part of that effort. Fairchild collected plants from all over the world so they could be studied and bred. He organized the USDA’s Office of Foreign Seed and Plant Introduction and served as its chairman for more than 20 years. He is credited with introducing about 30,000 plant species and variations into the United States, and he was instrumental in establishing gardens throughout the United States to screen plants with potential for improving our diets, gardens and landscapes.

When products do not meet a marketing order’s quality standards but are still edible, they can be diverted to secondary markets to minimize food waste while increasing producer returns. USDA photo courtesy of Ken Hammond.
USDA’s Food Waste Challenge is underway and federal marketing orders for fruits and vegetables continue to help out in the food donation effort. Under these industry self-help programs that are overseen by the Agricultural Marketing Service (AMS), groups decide minimum quality standards that benefit the entire industry. When products do not meet a marketing order’s quality standards but are still edible, they can be diverted to secondary markets to minimize food waste while increasing producer returns.
When this occurs, businesses have a couple of options: send the food to the processed market, donate the food to charities and food banks, or process the food into livestock feed. Nearly half of the active fruit and vegetable marketing orders also include comparable import regulations to ensure foreign products meet the same quality standards as those produced domestically.

Do you grow fruits and vegetables in your backyard or community garden? Do some of them come from trees?
Breadfruit, or ‘ulu, is an easy-to-grow, productive, nutritious, and starchy staple crop grown in many Pacific Islands, including Hawaii. It can be roasted, baked, boiled, fried or pounded into poi. In the past, many people grew breadfruit at home and in community gardens. However, many breadfruit trees have been cut down, especially in urban areas. Products such as breadfruit can have a helpful impact on Pacific islands such as Hawaii, imports about 85 percent of its food. Read more »
“Buying Local” has helped Rhode Island agriculture grow. We hope you have enjoyed these weekly spotlights of the states taken from the 2012 Census of Agriculture. Planning is already underway for the 2017 Census – stay tuned!
The Census of Agriculture is the most complete account of U.S. farms and ranches and the people who operate them. Every Thursday USDA’s National Agricultural Statistics Service will highlight new Census data and the power of the information to shape the future of American agriculture.
Rhode Island may be one of the smallest States in terms of agriculture but the 2012 Census of Agriculture shows Rhode Island has something most states don’t have – more farmers. The number of farmers in Rhode Island tallied 1,243, up slightly from 1,219 in 2007. As of 2012, almost 70,000 acres of our land are now dedicated to farming. That’s quite a bit, if you consider the fact that we are the smallest state in the Union.
Our agricultural growth is boosted by the “buy local” movement. According to the Census, Rhode Island growers sold almost $6.3 million worth, or 10.5 percent, of our agricultural products directly to consumers in 2012. This is the second highest percentage in the nation. Read more »
In Kentucky, the Whitley County School District customizes the fruit and vegetable options served in each school, based on the preferences of those particular students.
The following guest blog is part of our Cafeteria Stories series, highlighting the efforts of hard working school nutrition professionals who are dedicated to making the healthy choice the easy choice at schools across the country. We thank them for sharing their stories!

During the more than two decades I’ve worked in schools, I’ve witnessed what we now know to be true: healthy kids learn better. But I’ll also let you in on a secret: Not only are healthy foods better for our children’s long-term outcomes, kids like healthy foods! Read more »
