Climate change, migration, and the future of pandemics

In the late 18th century, a French zoologist visiting South Africa documented a deadly local livestock disease known as bluetongue. Today, some 240 years later, the disease can be found virtually worldwide. In FERN's latest story, produced with Ensia, Carson Vaughan explores a new way of understanding emerging infectious diseases, showing how climate change and migration can cause pathogens to spread in new and virulent ways.

Disease hitting Chinese hogs sure to spread in Asia

The world's leading hog producer, China has culled nearly 40,000 hogs in its attempts to stop African swine fever since the disease, deadly for hogs but no threat to humans, was spotted on its farms last month.

USDA calls meetings on potential updates to livestock trace-back rule

Four years after it issued a regulation on animal disease traceability, the USDA will hold seven regional meetings across the country to see how it's working and to discuss "potential next steps." The regulation put states and tribes in charge of developing trace-back systems and ended years of opposition to proposals for a federal database of livestock movement and ownership.

Poultry breeder culls Alabama flock that might have bird flu

FAO offers a helping hand in preventing antibiotic misuse

Antibiotics play a crucial role in treating disease in farm animals and plants, said the UN Food and Agriculture Organization in releasing an "action plan" to promote prudent use of antimicrobials. "Their use is essential to food security, to our well-being and to animal welfare," said the FAO, but the emergence of bacteria resistant to antibiotics is a threat to human health.
