In August 2015, a new, national outbreak of Seneca Valley A (SVA) began in the US, just one month after the Swine Health Information Center (SHIC) started operations. Looking back, we discovered Brazil had gone through an SVA outbreak during the late fall and winter of 2014-15 in the US, during their summer season, preceding the US occurrence.
The initial expression of African swine fever (ASF) in an ASF-free country like the US could be variable and unpredictable due to the myriad of factors including the epidemiology of ASF and the broad diversity of virulence among ASF virus isolates.
On September 5, 2018, U.S. Department of Agriculture (USDA) and Food and Drug Administration (FDA) officials met with U.S. pork sector groups – including the American Association of Swine Veterinarians, the National Pork Board, the National Pork Producers Council and the Swine Health Information Center – to evaluate additional measures to prevent the spread to the United States of African swine fever (ASF) currently active in China and some European nations. The information about prevention was shared late September. Diagnostic preparedness, surveillance and response to infection was also discussed and is shared with this Q and A.
Pork producers and feed suppliers are asking about feed safety due to the discovery and spread of African swine fever (ASF) in China where some feed ingredients, including soy bean meal, dried distillers grains and solubles (DDGS), amino acids, and vitamins, are manufactured and exported to the US. In response to this concern, swine industry groups including the Swine Health Information Center (SHIC), National Pork Board, National Pork Producers Council, and American Association of Swine Veterinarians reviewed existing research for information about appropriate feed holding time to enhance feed safety.
On September 14th, the OIE official report of the 1st ASF case in Belgium was released, confirming our previous report. On Saturday, 15th, the Federal Agriculture minister confirmed three new cases in the same area of the initial report, identified in wild boars found dead in the city of Etalle (Luxembourg province), near the border with France.
