ASF and PED alter China swine production: a podcast

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

‘At The Meeting’ Honoring Dr. Bob Morrison focuses on how African Swine Fever (ASF) and Porcine Epidemic Diarrhea virus (PEDv) have driven changes in farm design and biosecurity in China, allowing China’s swine industry to regain an estimated 80 percent of its swine herd.

Survival of swine pathogens in compost formed from preprocessed carcasses

This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.

This week, we are sharing a summary of a study published by Dr. Brent Pepin et al. from Pipestone Veterinary Services on the survival of swine pathogens in compost.

Key Points

  • Composting of preprocessed carcasses effectively eliminated infective PRRSV/PED under cold weather conditions
  • Compost biomass type (carbon source) may affect the short-term virus survival 
  • Environmental viral contamination (aerosolization and groundwater) from carcass preprocessing and windrow composting appears minimal under the conditions of the study
  • Compost reached temperatures that can adequately deactivate ASF

Growing African swine fever virus raises risk considerations

Dr. John Deen fron the University of Minnesota recently wrote a column in the National Hog Farmer about African Swine Fever virus and what the recent reports about virus spread mean for the industry.

SHIC and the UMN Help Uncover Risk for ASF Introduction into the US via Air Passengers’ Luggage

In 2018, African swine fever (ASF) spread into Western Europe, and, for the first time, into China and Southeast Asia. Such dramatic change in the global epidemiological conditions of ASF has resulted in concerns the disease may continue to spread into disease-free regions, such as the US. An analysis funded by the Swine Health Information Center and National Pork Board estimated the risk for introduction of ASF virus into the US through smuggling of pork in air passengers’ luggage. The analysis was conducted by the Center for Animal Health and Food Safety, College of Veterinary Medicine, University of Minnesota (OIE collaborating center on capacity building) and the Universidad Complutense de Madrid, Spain (OIE reference laboratory for ASF).

African Swine Fever (ASF) Reported in Vietnam

This report was published by the Swine Health Information Center on February 19th, in collaboration with the University of Minnesota, Swine Disease Global Surveillance group.

Although it has not been officially reported to the OIE, the Vietnamese Ministry of Agriculture and Rural Development (MARD) Animal Health Department released a communication confirming that ASF has been detected in two provinces in northern Vietnam, Hung Yen and Thai Binh, southeast of the capital city of Hanoi and at approximately 100 miles (160 km) from the Chinese border (Maps 1,2). Eight outbreaks have been reported, and all pigs in the affected farms have been culled. Neighboring farms are being tested as well. Local authorities initiated general measures to contain the outbreaks and disinfect the area through quarantine and restrictions of animal movements, but, so far, the total number of cases is still uncertain.
