1. IntroductionPorcine reproductive and respiratory syndrome (PRRS), a globally significant disease of pigs, is caused by the porcine reproductive and respiratory syndrome virus (PRRSV) [1]. Infection of breeding female swine with PRRSV results in reduced animal welfare, poor reproductive performance, and significant economic loss to farmers [2]. To control PRRS, PRRSV entry into breeding herds mu ...

1. IntroductionContamination of feed ingredients or complete feed has been shown to be a potential route of pathogen transmission [1,2]. To control this potential route of disease transmission, efforts can focus on the prevention of the contamination step from occurring or implementing strategies to reduce the survival of the bacteria or virus in the material, and thus reduce the likelihood of ca ...

1 INTRODUCTIONNorth America currently imports plant-based feed ingredients, such as soybean meal, from countries that are endemically infected with viruses of economic and pathologic significance to swine including porcine epidemic diarrhoea virus (PEDV), Seneca virus A (SVA), porcine reproductive and respiratory syndrome virus (PRRSV), classical swine fever virus, pseudorabies virus, foot and mou ...

IntroductionThe link between diet and disease transmission has raised concerns that U.S. herds could become infected with foreign pathogens through contaminated feed and feed ingredients originating from countries with endemic disease and lax sanitation and quality assurance procedures. Experimental data has already demonstrated that some feed ingredients, particularly soy-based products, can ...
