| contents | The U.S. launched the Secure Pork Supply (SPS) Plan for Continuity of Business, a voluntary program providing foreign animal disease (FAD) guidance and setting biosecurity standards to maintain business continuity amid FAD outbreaks. The role of biosecurity in disease prevention is well recognized, yet the U.S. swine industry lacks knowledge of individual farm biosecurity plans and the efficacy of existing measures. We describe a multi-sector initiative that formed the Rapid Access Biosecurity (RAB) app consortium with the swine industry, government, and academia. We (i) summarized 7,625 farms using RABapp, (ii) mapped U.S. commercial swine coverage and areas of limited biosecurity, and (iii) examined associations between biosecurity and occurrences of porcine reproductive and respiratory syndrome virus (PRRSV) and porcine epidemic diarrhea virus (PEDV).
RABapp, used in 31 states, covers ~47% of U.S. commercial swine. Of 307 Agricultural Statistics Districts with swine, 78% (238) had <50% of those animals in RABapp. We used a mixed-effects logistic regression model, accounting for production company and farm type (breeding vs. non-breeding). Requiring footwear/clothing changes, having multiple carcass disposal locations, hosting other businesses, and greater distance to swine farms reduced infection odds. Rendering carcasses, manure pit storage or land application, multiple perimeter buffer areas, and a larger animal housing area increased risk. This study leveraged RABapp to assess U.S. swine farm biosecurity, revealing gaps in SPS plan adoption that create vulnerable regions. Some biosecurity practices (e.g., footwear changes) lowered PRRSV/PEDV risk, while certain disposal and manure practices increased it. Targeted biosecurity measures and broader RABapp adoption can bolster industry resilience against foreign animal diseases. |
