Ever since the introduction of Porcine Epidemic Diarrhoea virus into the United States in 2013, the US has been extra aware of the risk of animal diseases entering through feedstuffs. No wonder that the role of feed gets a major emphasis in US research on African Swine Fever. What role exactly can feed play in transmission and mitigation of the virus?

Swine enteric coronaviruses, including Porcine Epidemic Diarrhoea virus (PEDv) and porcine deltacoronavirus (PDCoV), are considered the last major transboundary swine diseases introduced into the US pig herd in 2013 and 2014, respectively. Several epidemiological analyses into the introduction and rapid spread across new farms revealed the potential source of the virus as contaminated feed and feed ingredients. Although there are other risk factors, such as illegally smuggled pork products, for introduction of ASFv into the US, plant-based feeds and feed ingredients are of particular concern due to several unique characteristics. What are the relevant questions to ask? Which ingredients support ASFv stability? Identifying which feed ingredients provide an environmental matrix that supports ASFv stability is an important step in determining risk. To evaluate this risk using a transboundary shipment model, in 2018 a team of researchers led by Dr Scott Dee selected 12 feeds, ...
