USDA Updates on HPAI

Animals moving interstate to an exhibition, show, or sale may pass the 7-day testing window; is it possible to skip additional testing to return to the first farm? Animals moving interstate to an exhibition, show, or sale must have a negative test result from samples collected within 7 days of movement. These animals may travel to their home herd using the same negative test result provided the exhibition, show, or sale does not exceed 10 days of length.
Limit animal comingling of animals and follow biosecurity protocols.
Please check with each exhibition event to understand individual guidelines in place for dairy cattle.
Additional guidance about minimizing transmissions at livestock exhibitions can be found here.

Video: Season 7, Episode 4: Using Data to Better Manage PRRSV

PRRS continues to be one of the biggest challenges facing pork producers, but each outbreak can also provide valuable information about herd recovery, losses and the management decisions that follow.In this episode, Dr. Ana Paula Serafini Poeta Silva, a research scientist at Iowa State University, discusses the PRRS Outbreak Management Program, or POMP, and what researchers have learned from a database containing information from more than 700 breeding-herd outbreaks. She explains how POMP uses data from individual outbreaks to establish benchmarks producers can use to better understand what to expect during recovery, including potential losses and the time it may take for a herd to return to baseline production. The conversation also explores how PRRS management has evolved, including the role of live virus inoculation and modified-live vaccines.
