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.
As the weather heats up this summer, many of us are firing up our grills and going on picnics. But one thing we all want to avoid is getting food poisoning from the food or beverages we consume.
Each year, an estimated 48 million Americans get sick, 128,000 are hospitalized and 3,000 die of foodborne diseases. An obstacle to extensive testing of foods for microbes, pathogens and toxins that cause food poisoning is equipment cost, according to an Agricultural Research Service (ARS) scientist. Read more »
We’re looking forward to celebrating National Farmers Market Week with markets across the nation, August 7-13! Market managers and organizers can download graphics and templates to create their own celebration materials.
What are you doing August 7 through 13? That’s National Farmers Market Week – a time to celebrate the farmers, ranchers and local food businesses, as well as the communities that support them. USDA Secretary Tom Vilsack has officially declared August 7 through August 13, 2016 as the 17th annual National Farmers Market Week, highlighting the key role that farmers markets play in bringing communities together around agriculture. And with more than 8,500 farmers markets around the country, there are lots of opportunities to celebrate!
I will be celebrating that week by visiting markets across the nation, before wrapping up the week at the USDA’s Farmers Market in Washington, D.C., on Friday, August 12. You can celebrate at your local market too! The National Farmers Market Directory makes it convenient to find farmers markets in your area with weekday, weekend, and evening options. Read more »
A gypsy moth caterpillar on a leaf in Massachusetts
While being outside in Massachusetts this June, I first noticed it. A lot of leaves were falling from the trees, only these were chewed leaf parts, not whole leaves.
Similar to the children’s book, The Very Hungry Caterpillar written by Eric Carle, some leaves didn’t just have chew marks but actual holes going straight through them. Unlike the children’s book, this damage isn’t being caused by a friendly caterpillar who turns into a butterfly. Instead it’s the result of ravenous gypsy moth caterpillars feeding…and feeding. It’s so bad that in some areas, on walkways and roadways, it looks like fall. Brown, dried up leaves are a contrast to summer’s lush greenery. Read more »
An example of the damage feral swine can have on water quality.
How does the old saying go? That’s right, “Happier than a pig in mud!” Feral swine are no exception to this old farmer’s anecdote. Because they lack sweat glands, wallowing in mud and water is an instinctual behavior necessary for them to maintain a healthy body temperature. Unfortunately this behavior has cascading impacts, not only to water quality in individual streams, ponds, and wetlands, but to entire watersheds and ecosystems.
Excessive feral swine traffic around wallows and water sources causes erosion along stream banks and shorelines. Sounders, or family groups, of feral swine spend large amounts of their day around the wallow, especially in hot weather, which means they leave significant amounts of urine and feces in and around the water. The impacts to water quality go far beyond the immediate wallow site when silt, excrement, and potentially harmful pathogens, are washed down stream. Read more »

July is the height of summer grilling season and throughout the month USDA is highlighting changes made to the U.S. food safety system over the course of this Administration. For an interactive look at USDA’s work to ensure your food is safe, visit the USDA Results project on Medium.com and read Chapter Seven: Safer Food and Greater Consumer Confidence.
USDA’s National Institute of Food and Agriculture (NIFA) supports innovative research to address pressing issues. We are looking at the many ways USDA supports safe food this month, including this report from Sylvia Kantor at Washington State University’s College of Agricultural, Human, and Natural Resource Sciences:
Consumer demand for safe, high-quality, additive-free packaged foods is growing. Thanks to two recent investments in innovative food processing technology based on microwave energy, Washington State University (WSU) is advancing toward meeting this demand.
USDA’s National Institute of Food and Agriculture (NIFA) awarded WSU $4 million to establish a Center of Excellence that will accelerate the technology transfer to mainstream commercial markets. This is the first Center of Excellence on Food Safety Processing Technologies funded by NIFA’s flagship program, the Agriculture and Food Research Initiative. Read more »
Cassie Munsey, 31, Monticello, Ky., checks in on the bull on her 14-acre beef cattle farm she purchased in 2013. As a new farmer, Munsey appreciates the increased flexibility in USDA programs allowing her to get her operation up and running.
Farmers are unique in that they touch every single American every single day, because we all eat. Ensuring a continuity of agriculture is important to all of us. To take the pulse of U.S. agriculture, we conduct a Census of Agriculture every five years which gives us a comprehensive analysis of agriculture in America and supplements information from more than 400 other surveys we conduct each year.
Our last census was in 2012, and the resulting data showed a decline in the number of new and beginning farmers compared to the previous census in 2007. On top of that decline, we saw the average age of American farmers trending upward to 58 years old. The USDA took these two pieces of information and recognized the need to encourage new and beginning farmers. Read more »
