USDA reinforces national vigilance during African Swine Fever Week as experts warn of major risks to U.S. pork production and the wider agriculture sector.
March 1–7 marks African Swine Fever (ASF) Week in 2026, a time when the United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) reinforces the importance of preventing this devastating disease from reaching U.S. soil.
In a new editorial, Dr. Alan Huddleston, Acting U.S. Chief Veterinary Officer, offers insights into the ongoing risks of ASF and the steps needed to safeguard the nation’s swine industry.
As many swine farmers know, ASF is a highly contagious viral disease affecting pigs, with mortality rates reaching up to 100 percent. While the virus poses no danger to humans, it has led to catastrophic losses in Asia, Europe, and other regions. Its introduction into the United States would have severe consequences for farmers, processors, and the broader agricultural economy.
APHIS remains unwavering in its efforts to keep the disease out of the country, using strong surveillance, international coordination, and enhanced biosecurity measures.
“As we recognize National Pig Day on March 1, it’s a reminder of just how important pigs are to agriculture, science, and society,” Dr. Huddleston writes. “It’s also a timely call to stay vigilant against ASF.”
Economic Impacts Could Be Far‑Reaching
The U.S. pork sector plays a major role in both domestic and global food markets. Disruptions from ASF would ripple across the supply chain.
“It is undeniable that the economic repercussions of ASF would be far‑reaching in the U.S. because pork is a staple in many American diets, appearing in everything from breakfast sausages to holiday hams,” Dr. Huddleston explains.
He warns that pork shortages could drive prices higher, push consumers toward alternative proteins, and trigger wider market instability.
Four Practical Steps to Help Prevent ASF
Dr. Huddleston outlines four key actions that producers, travelers, hunters, and the general public can take to help keep ASF out of the United States:
1. Avoid bringing pork products across borders
Pork snacks, cured meats, and food souvenirs can harbor the ASF virus even after processing.
Always declare food items when entering the U.S. to protect agriculture and avoid penalties.
2. Take precautions when traveling abroad
Those visiting farms or coming into contact with pigs internationally should: Clean clothing and footwear thoroughly Avoid farm visits or pig contact for at least five days after returning
3. Be alert when hunting or hiking
Wild pigs and feral swine can carry and spread ASF. Hunters and outdoor enthusiasts may unknowingly transport the virus on boots or gear. Report sick or dead feral swine to USDA Wildlife Services at 1‑866‑4‑USDA‑WS.
4. Spread awareness—not disease
Most people know little about ASF or its implications. Sharing accurate information helps build a national network of vigilance.
“The time to act is now, for the sake of our farms, our economy, and the well-being of all Americans,” Dr. Huddleston says in his conclusion. “Together, we can work to keep ASF out of the U.S. and protect our pigs and food supply for generations to come.”
