Flushed Away…Probing For Antibiotic Presence in Our Food Supply

It’s a question with major public-health implications: Could antibiotics and other widely used medications get into our food supply when they are flushed into our sewers?

To try to answer that question, researchers from USDA and Penn State University (PSU) assessed whether some commonly used pharmaceuticals could get into a wheat crop irrigated with recycled wastewater. Read more »

Wheat Blast, Bangladesh, and Biosecurity: NIFA-Funded Research Works for Global Food Security

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.

An epidemic of wheat blast is underway in Bangladesh, published reports say, and losses may be substantial in the six southeastern districts where it has been reported. Wheat blast is a crop disease caused by the Triticum pathotype of the fungus Magnaporthe oryzae (MoT). In nations where broad wheat blast epidemics have occurred, 30 percent losses have been noted, but localized areas have experienced 50-100 percent losses, according to Dr. Barbara Valent, fungal molecular geneticist at Kansas State University (KSU).

The U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA), through its Agriculture and Food Research Initiative (AFRI), has provided nearly $5.4 million since 2009 to support research on wheat and rice blast. KSU leads a multi-institutional research project that brings together expertise from University of Arkansas, University of Kentucky, the Ohio State University, Purdue University, and USDA’s Agricultural Research Service.

High Five: NIFA-Funded Research Improves Agriculture

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.

The National Institute of Food and Agriculture (NIFA) invests in agricultural sciences that turn research into action by taking groundbreaking discoveries from laboratories to farms, communities, and classrooms.  Scientific advances that result from NIFA-funded research – more than $1.5 billion in fiscal year 2015 – enhance the competitiveness of American agriculture, ensure the safety of the nation’s food supply, improve the nutrition and health of communities, sustain the environment and natural resources, and bolster the economy.  The following blogs are examples of the thousands of NIFA projects that impact the lives of Americans every day.

Plant diseases can easily cross international borders and damage crops in neighboring countries. The good news is that in Pakistan, scientists with USDA’s Agricultural Research Service (ARS) are working toward a solution.

David Marshall, a research leader at the USDA-ARS Plant Science Research Unit in Raleigh, North Carolina, has been collaborating with Pakistani scientists in recent years to prevent losses there from wheat rust diseases including Ug99, a fungal disease that threatens wheat production worldwide. Ug99, which was first reported in Uganda in 1999, has not yet been detected in Pakistan (or in the United States). But it is transmitted by wind-blown spores and has been detected in neighboring Iran. It is widely expected to reach Pakistan in the near future. Read more »

The New Wave of Wheat: Increasing Resistant Starch to Improve Health Benefits

Bread and pasta are mealtime favorites and household staples for many, but carbohydrates may also present a problem for many who struggle with health issues brought on by obesity.  With this in mind, researchers are developing wheat that has positive health implications.

A University of California-Davis-led Triticeae Coordinated Agricultural Project (T-CAP) is introducing changes into durum wheat genes that can increase resistant starch content by more than 750%. Read more »

South Dakota Becoming an Agriculture Powerhouse

South Dakota Infographic

South Dakota agriculture is growing by leaps and bounds! Be sure to check back next week for highlights of another state from the 2012 Census of Agriculture.

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.

South Dakota is growing to be quite an agricultural powerhouse, as the most recent Census of Agriculture results showed. In 2012, the year for which the latest Census was conducted, our farmers and ranchers sold more than $10 billion worth of agricultural products. That’s an incredible 55 percent increase from 2007 Census of Agriculture.

Our farms are also defying a downward national trend. While the number of farms is decreasing in most states, in South Dakota, our farm numbers actually grew by 3 percent between the 2007 and 2012 censuses of agriculture. As of 2012, there are nearly 32,000 farms in The Mount Rushmore State. Read more »
