One of the greatest privileges of serving as Alice was working with the Dairy Innovation Hub, a collaboration between UW–Madison, UW–Platteville, and UW–River Falls. This partnership allowed me to highlight the incredible research being done in dairy science, from improving sustainability and animal health to advancing food safety and agricultural technology. These researchers and students are writing the next chapter of our state’s agricultural legacy, one data set at a time.

‘We know what to do’: Wisconsin fairs continue bird flu testing requirements for cows

Keith Poulsen, director of the Wisconsin Veterinary Diagnostic Laboratory, said the impact was disappointing last year, especially given the amount of work exhibitors put into getting an animal ready for show.

“I’m hoping that with one year of experience under their belt, they feel more comfortable to be able to submit that testing and make sure that we have robust cow classes in these shows,” said Poulsen, whose lab processes all of the avian flu samples taken in the state. “It’s part of our culture, and we missed that last year.”

The effect on U.S. forecasting will be “like losing your eyesight: slow and torturous,” said Jonathan Martin, a professor of atmospheric sciences at the University of Wisconsin.

Americans who have grown up amid the “unheralded revolution” of ever-more-precise weather forecasts will find themselves in a world growing blurrier — even as the weather grows ever more volatile, Martin added.

Wisconsin celebrates Dairy Month as state trade exports reached $8.2 billion last year

Chuck Nicholson is an associate professor of agriculture and economics at the University of Wisconsin-Madison. He said 20% of the milk produced ends up outside the U.S.

Nicholson said he doesn’t expect the dairy export market with China to be significantly impacted for the time being and that’s a good thing for Wisconsin.

“Cheese is definitely important as an export product, and it’s obviously quite important in Wisconsin. The other part about that is that with cheese typically comes whey, and we’re also a major exporter — from the State of Wisconsin — of whey products, and China is also a major market for our whey products as well,” Nicholson said.

Survey finds Wisconsin farmers value sustainable practices

Wisconsin Public Radio

A recent survey of Wisconsin’s farmers found that 56 percent of them believe climate change is happening. Another 26 percent think it isn’t happening, and 18 percent are unsure.

Michael Bell, the University of Wisconsin-Madison professor who helped conduct the study, said attitudes and behaviors don’t always match up. Bell found encouragement in how the farmers are acting, not their beliefs. The same survey asked farmers if they are practicing any of 15 different sustainable agricultural practices.

“Without the continued research that’s made possible with federal funding, it would set us back,” said John Shutske, an agricultural safety and health specialist at the University of Wisconsin-Madison. “We’ve seen over the last several decades a pretty dramatic decrease overall in our farm fatality rate. And while I think [the number of deaths] would probably plateau, I don’t think we would be able to continue to make the kind of progress that we’ve had.”

Kevin Jarek, regional crops and soils educator with UW-Madison’s Division of Extension for Outagamie & Winnebago counties, noted, “If I were to go to counties like Shawano and Waupaca, especially the western parts of those counties, they get much lighter in soil. It’s a sandy loam texture, whereas here as we get closer to Lake Michigan, we tend to have a lot of clay.”

Tariffs could churn up trouble for Wisconsin’s dairy industry

Tariffs enacted under the Trump administration could have significant impacts on the agriculture industry in the U.S. and particularly on the dairy industry in Wisconsin, according to University of Wisconsin associate professor of agriculture and economics Chuck Nicholson.

“The tariffs have a number of different impacts, whether that be the tariffs we are placing on imports from other countries or the tariffs that other countries will place on us,” Nicholson said.

We’ve entered a forever war with bird flu

The Verge

“We thought this was a one-off: one bird to one cow, and we wouldn’t see that again,” says Peter Halfmann, a virologist at the University of Wisconsin-Madison’s Influenza Research Institute.

Yet the more severe human cases are concurrent with the spread of a recently mutated, potentially more dangerous version of the virus called the D1.1 genotype. D1.1. is now circulating among wild birds and poultry, and it has spilled over into dairy cows at least twice in 2025, according milk testing data from the Agriculture Department. With D1.1, Halfmann explains that the threshold for cross-species transfer is “much lower than we previously thought.”

The vast majority of raw milk cheese should be safe after the 60-day aging window, according to Keith Poulsen, DVM, PhD, a clinical associate professor of medical sciences at the University of Wisconsin-Madison School of Veterinary Medicine.

“We have a lot of history and data to back that up,” Poulsen told Verywell in an email. “Unfortunately, the data from Cornell suggests that if raw milk cheeses were made on an affected farm, they would not be recommended for consumption.”

Zero gravity greens: How Earth’s farmers could benefit from spaceflight cultivation

Simon Gilroy is a professor of botany at the University of Wisconsin-Madison who regularly designs spaceflight experiments with NASA. When asked if he thinks we are using astrobiological research enough to improve our sustainability on Earth, Professor Gilroy pointed to the discourse around urban farming, an approach which involves moving some elements of cultivation and productivity into cities instead of using agricultural fields.

Speaking to Interesting Engineering, Professor Gilroy observed that urban environments have many of the same problems as growing plants in space, including challenges around water delivery, maintaining environment within the desired parameters and dealing with pathogen outbreaks. “So there’s a lot of technology development going on in space, which has real applications when you come back to thinking about those kinds of applications on Earth,” he noted.

Randy Jackson, a professor of grassland ecology at University of Wisconsin-Madison who was not involved in the study, said he has found similar results in his own research showing that grass-fed beef has higher emissions assuming the same demand. In fact, Eshel’s team cited his work. But he worries that the study is too focused on minimizing emissions “without concern for the environmental impacts beyond GHG load to the atmosphere,” like biodiversity and soil and water quality, he wrote in an email.

“In Japan, fruits are not just food. Fruits really have a lot of symbolic meaning and cultural meaning,” said Soyeon Shim, a scholar of consumer and financial behavior who’s studied the country’s fruit market. “High-end fruits are used as a gift. And gifts are a very important practice in Japan.”

A $19 strawberry isn’t unusual there, said Shim, who’s the dean at the University of Wisconsin-Madison’s School of Human Ecology. The high-quality fruit is grown in controlled greenhouses and requires a lot of hand labor, she said.

“I wouldn’t ever buy a $19 strawberry to get my daily intake for vitamin C. So it isn’t designed for everyday consumption,” Shim said.

“Unfortunately, I don’t see prices improving in the near future,” Kean said. “We still don’t have a handle on stopping bird flu.”

Farmers fear more pain from Trump’s trade war

Time

About 20% of U.S. milk production is exported annually, with about 40% of that going to Canada, Mexico, and China, according to Chuck Nicholson, an associate professor at the University of Wisconsin-Madison. If the domestic dairy industry gets only a little more milk than traders were expecting, prices drop as a result, Nicholson says. So if the dairy industry started trying to sell that 20% domestically instead of exporting it, prices would plummet, making it difficult for farmers to continue to operate.

Dan Smith with UW Extension’s integrated pest and crop management, says the recent snowfall is good for their crops, but it may not be enough to keep crops like alfalfa, wheat, and small grains from winter kill.

“There are a couple of factors that we should consider when we’re thinking about winter kill, for alfalfa, we’re primarily considering those conditions where we don’t have snow cover, like December and January this year,” explained Smith.
