Nearly 13 years ago, China shut its borders to U.S. beef in reaction to the first U.S. case of mad cow disease. Now, the government says it will end the ban, leaving U.S. officials and cattle producers asking for a timeline, says the Wall Street Journal.

Vermont Sen. Bernie Sanders told a soda industry group, in the form of a cease-and-desist letter, to stop using him in its campaign against soda taxes in California's Bay Area, says Politico. Sanders says he has not taken a position on referendums in San Francisco and Oakland and it is "false" and "misleading" for the American Beverage Association to feature him in advertising.

Researchers at University College in Dublin, Ireland say that feeding seaweed, a popular ingredient in ancient Chinese medicine, to sows can improve the health of their offspring and reduce the use of antimicrobials, says the Aberdeen (Scotland) Press and Journal.

The Justice Department, which filed an anti-trust suit to prevent Deere & Co. from buying Precision Planting, recently telephoned farmers in the Midwest to ask about the market dynamics for high-speed planters, says DTN.

Clover Storenetta Farms, based in northern California, "will become the first major dairy in the United States to sell non-GMO conventional milk," says the San Francisco Chronicle. "With its newest product, Clover is betting that there is also a market for conventional milk produced without GMOs that is cheaper than organic milk."

The Los Angeles school board voted, 6-1, to loosen its ban, dating from 2011, on sugary, flavored milk in lunchrooms, in the hopes that more relaxed rules will reduce food waste and encourage consumption of plain milk, says the Los Angeles Times. "We wouldn't serve caramel apples to increase apple consumption," objected Brent Walmsley, founder of the advocacy group Sugarwatch.

Countries must start figuring out how much food they waste if they’re going to meet the U.N.’s Sustainable Development Goal of halving global food waste and lowering food loss by 2030, says a report out by Champions 12.3, a coalition of government, business, and research organizations.

Mexico is scheduled to fully implement national regulations on organic production and marketing. "To maintain market access for U.S. organic products," USDA says the two countries are working toward equivalency in organic standards, which would allow products certified organic in one country to be sold in the other without having to go through a second round of certification and inspection.

“Particularly ill-suited” to climate change, the avocado might once again become a luxury item, says The Atlantic. Avocados do poorly under exactly the kinds of conditions — higher temperatures and drier weather — that are becoming more common in the plant’s growing regions worldwide.

A longtime advocate for, and researcher of, organic agriculture, Rodale Institute is launching the Organic Farmers Association, which it says will be the first U.S. group speaking solely for organic farmers. The USDA reported last week that there are 12,818 certified organic farms covering 4.36 million acres, a small share of the 2.07 million farms and 912 million acres of farmland in the country.

A day after warning of potential disruptions worldwide due to climate change, President Obama signed a memorandum "establishing that the impacts of climate change must be considered in the development of national security-related doctrine, policies and plans," said the White House. The memorandum created a Federal Climate and National Security Working Group involving 20 agencies in the job of identifying security priorities affected by climate change and to share information about how to respond to it.

Peter Glieck, a founder of the think tank Pacific Institute, is blunt: California leaders made "a big mistake" earlier this year when they removed a requirement to cut water use by 25 percent, says the New York Times. Conservation during June, July and August was lower than during the summer of 2015 and the state is in the fifth year of drought.

With few national guidelines, pet food is a Wild West of food safety, says Modern Farmer. Pet food is technically overseen by the FDA, but due to limited resources the agency has handed over that responsibility to the Association of American Feed Control Officials (AAFCO), which has no regulatory control and can only ask companies to adhere to voluntary guidelines.

Many of the world’s wild mammals, from primates to bats, are being hunted to extinction for bushmeat, says The Guardian. In the first global report on the ecological impact of human hunting, researchers warn that without better management practices not only will species disappear, but hundreds of millions of rural people who rely on bushmeat for food could go hungry.

Agriculture Secretary Tom Vilsack, nearing the end of eight years at USDA, knows the type of person who would fit perfectly as his replacement at USDA. "If I were to offer advice [it would be] find a governor who cares about agriculture," Vilsack told reporters.

The International Agency for Research on Cancer started a global debate by rating glyphosate, the most widely used weedkiller in the world, as "probably carcinogenic to humans" while the EPA says its studies indicate it is "not likely to be carcinogenic to humans at doses relevant to human health." Harvest Public Media says the difference in view is partially explained by the way the agencies chose to evaluate the issue.
