African Swine Fever Protection Zone

Aug 27, 2021

The protection zone is another important step in keeping African swine fever out of the U.S.

USDA’s announcement that it will be pursuing a Foreign Animal Disease protection zone in Puerto Rico and the U.S. Virgin Islands is another important step in keeping African swine fever (ASF) out of the U.S. and territories after the recent identification of cases in the Dominican Republic.

Prevention efforts are already in place in Puerto Rico, but formal designation from the World Organisation for Animal Health (OIE) allows USDA to seek zone recognition from trading partners prior to an outbreak, so the U.S. may continue to export pork if ASF is detected in Puerto Rico or the U.S. Virgin Islands. As part of the zoning process, USDA will also work to increase awareness and continue surveillance in Puerto Rico.

USDA has been working with officials in the Dominican Republic to control ASF there as well. Combined with today’s announcement and the on-farm disease prevention efforts of producers here in the U.S., these strong controls are helping protect the commercial swine herd from the disease.

Video: Sweetener Effects on Gut Health - Dr. Kwangwook Kim

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Kwangwook Kim, Assistant Professor at Michigan State University, discusses the use of non-nutritive sweeteners in nursery pig diets. He explains how sucralose and neotame influence feed intake, gut health, metabolism, and the frequency of diarrhea compared to antibiotics. The conversation highlights mechanisms beyond palatability, including hormone signaling and nutrient transport. Listen now on all major platforms!

“Receptors responsible for sweet taste are present not only in the mouth but also along the intestinal tract.”

Meet the guest: Dr. Kwangwook Kim / kwangwook-kim is an Assistant Professor at Michigan State University, specializing in swine nutrition and feed additives under disease challenge models. He earned his M.S. and Ph.D. in Animal Sciences from the University of California, Davis, where he focused on intestinal health and metabolic responses in pigs. His research evaluates alternatives to antibiotics, targeting gut health and performance in nursery pigs.
