In January 2018, a handful of farmers at a major Iowa pork industry gathering attended a session on the threat of foreign animal diseases. A year later, several dozen people showed up, spurred by the march of African swine fever across China.

“This risk of African swine fever is real,” veterinarian Craig Rowles told the crowd at the Iowa Pork Congress. “And as producers, we need to be very cognizant of that.”

Scientific research could deliver transformative technologies to the food system over the next decade, according to a new report from the National Academies of Sciences, Engineering and Medicine. Advances in things like gene editing, data sharing and microbiology could make crops more resilient to climate change and livestock more environmentally sustainable.

Though there have not been any U.S. cases of the strain of avian flu that has killed more than 140 people in China this year, the U.S. Department of Agriculture’s head veterinarian says the agency is making preparations to combat the deadly virus in case it reaches North America. 

The USDA’s Dr. Jack Shere stresses that it's impossible to predict how far a particular bird flu strain may travel or mutate. In the meantime, however, scientists are on alert. 

In a hog barn in rural Iowa, veterinarian Paul Thomas’s approach sends pigs scurrying. He watches for unusual behavior. As he walks the length of the barn, Thomas notices one of the two-month-old hogs nestled against the railing at the edge of its pen and reaches over to gently pet the pig’s back. The pig shakes its head and drowsily gets up.

“He’s just sleepy,” Thomas says, and by the time he’s spoken the words, the pig has trotted off to join its pen-mates.

In the next room, Thomas hears something different.

Why Scientists Disagree On RoundUp’s Cancer Risk

Nov 15, 2016

After dueling reviews of research studies, scientific panels from the U.S. government and the World Health Organization are having a hard time agreeing whether glyphosate, the most common weed killer in the United States, can cause cancer. Known by the brand name RoundUp, glyphosate is sprayed on farm fields and lawns all across the country.

With the legal battle raging over the implementation of controversial Obama Administration clean water rules, the next president is likely to face the daunting task of formulating a comprehensive plan to cut-down on water pollution from Midwest farms.

Showing livestock at the county fair can be a great source of pride for a youngster in farm country. It can also be a source of a novel flu virus capable of starting a pandemic.

According to new findings from the Centers for Disease Control and Prevention, 18 people – 16 of them children – tested positive for strains of influenza never before seen in humans after attending agricultural fairs in Ohio and Michigan in August of this year.

Food giant General Mills is recalling millions of pounds of flour milled in Kansas City, Missouri, on suspicions that the product is contaminated by a dangerous strain of E. coli bacteria.

Thirty-eight people in 20 states have been infected in the outbreak, according to the U.S. Centers for Disease Control and Prevention. Ten have been hospitalized.

On a cold windy morning, Kelly Nissen feeds the cows at the Iowa State University Beef Nutrition Farm north of Ames. Far from just tossing hay, he weighs out specific rations and carefully delivers them to numbered feed bunks.

“When you’re feeding, you’re always double-checking yourself to make sure it’s going in the right lot,” Nissen says.
