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.
Although it has not been officially reported to the OIE yet, preliminary reports indicate that ASF has been
confirmed in two wild boars near the southern village of Étalle, in the province of Luxembourg, which is
located 8 miles (12 km) from the border with France and 11 miles (17 km) from Luxembourg. It appears to
have jumped a considerable distance from previously affected countries, about 300 miles (500 km) from the
border with the Czech Republic, 500 miles from Hungary, and 750 miles (1,200 km) from the border with
Romania (approximate distances). The Belgian authorities report they are working to prevent the possible
spread of the disease among wild boar and onto pig farms.
