Dan Charles

Dan Charles is NPR's food and agriculture correspondent.

Primarily responsible for covering farming and the food industry, Charles focuses on the stories of culture, business, and the science behind what arrives on your dinner plate.

This is his second time working for NPR; from 1993 to 1999, Charles was a technology correspondent at NPR. He returned in 2011.

During his time away from NPR, Charles was an independent writer and radio producer and occasionally filled in at NPR on the Science and National desks, and at Weekend Edition. Over the course of his career Charles has reported on software engineers in India, fertilizer use in China, dengue fever in Peru, alternative medicine in Germany, and efforts to turn around a troubled school in Washington, DC.

In 2009-2010, he taught journalism in Ukraine through the Fulbright program. He has been guest researcher at the Institute for Peace Research and Security Policy at the University of Hamburg, Germany, and a Knight Science Journalism fellow at the Massachusetts Institute of Technology.

From 1990 to 1993, Charles was a U.S. correspondent for New Scientist, a major British science magazine.

The author of two books, Charles wrote Master Mind: The Rise and Fall of Fritz Haber, The Nobel Laureate Who Launched the Age of Chemical Warfare (Ecco, 2005) and Lords of the Harvest: Biotech, Big Money, and the Future of Food (Perseus, 2001) about the making of genetically engineered crops.

Charles graduated magna cum laude from American University with a degree in economics and international affairs. After graduation Charles spent a year studying in Bonn, which was then part of West Germany, through the German Academic Exchange Service.

Bird flu has been striking chicken and turkey farms in parts of the West and Midwest. This past week, it hit a flock of millions egg-laying chickens in northeastern Iowa. Update 4/22/2015: The USDA now says that around 3 million birds were affected in the Iowa facility — down from a previous estimate of 5 million.

The state of California is asking a basic question right now that people often fight over: What's a fair way to divide up something that's scarce and valuable? That "something," in this case, is water.

There's a lot at stake, including your very own nuts, fruits and vegetables, because most of the water that's up for grabs in California goes to farmers. This year, some farmers will get water, and others will not, simply based on when their land was first irrigated.

California is parched. Wells are running dry. Vegetable fields have been left fallow and lawns are dying. There must be some villain behind all this, right?

Of course there is. In fact, have your pick. As a public service, The Salt is bringing you several of the leading candidates. They have been nominated by widely respected national publications and interest groups.

There's just one problem: Not all of these shady characters live up to their nefarious job description. Let us explain.

A planet that is warming at extraordinary speed may require extraordinary new food crops. The latest great agricultural hope is beans that can thrive in temperatures that cripple most conventional beans. They're now growing in test plots of the International Center for Tropical Agriculture, or CIAT, in Colombia.

An international committee of cancer experts shocked the agribusiness world a few days ago when it announced that two widely used pesticides are "probably carcinogenic to humans." The well-respected International Agency for Research on Cancer published a brief explanation of its conclusions in The Lancet and plans to issue a book-length version later this year.

There's a researcher at the RAND Corporation who has been building a reputation as a curmudgeonly skeptic when it comes to trendy ways to fight America's obesity epidemic.

For the past two years, at an undisclosed location in the Upper Midwest, a large commercial egg farm has been probed with every tool of modern science. Researchers have collected data on feed consumed, eggs produced, rates of chicken death and injury, levels of dust in the air, microbial contamination and dollars spent. Graduate students have been assigned to watch hours of video of the hens in an effort to rate the animals' well-being.

In the heart of California's Central Valley, a vast expanse of orchards, vineyards, and vegetable fields, lies a small collection of aging peach trees. Farmer Mas Masumoto's decision to preserve those trees, and then to write about it, became a symbol of resistance to machine-driven food production.

Yet the Masumoto farm's story isn't just one of saving peaches. It's become a father-daughter saga of claiming, abandoning, and then re-claiming a piece of America's agricultural heritage.

When it comes to the current controversy over antibiotic use on farm animals, milk is in a special category.

Lactating cows, unlike hogs, cattle or chickens that are raised for their meat, don't receive antibiotics unless they are actually sick. That's because drug residues immediately appear in the cow's milk — a violation of food safety rules.

Milk shipments are tested for six of the most widely used antibiotics, and any truckload that tests positive is rejected. So when cows are treated, farmers discard their milk for several days until the residues disappear.

The political battle over immigration, now provoking a confrontation between Congress and the White House, touches all of us in one very direct way: our food. That salad mix, and those apples, may well have been harvested by workers who arrived here in the U.S. illegally.
