Biosecurity measures preventing disease entry on pig farms are simultaneously welfare investments. Preventing infectious disease protects pigs from suffering and producers from economic losses.
Disease prevention through biosecurity is among the highest-return welfare investments available to pig producers, protecting animals from the severe suffering caused by PRRS, ASF, and other pathogens. The welfare harm of major disease outbreaks is catastrophic at herd scale — PRRS causes chronic respiratory disease, reproductive failure, and compromised immunity across affected herds; ASF causes hemorrhagic fever with high mortality requiring culling of surviving animals. The human-animal relationship and care quality at facilities with strong biosecurity cultures tends to be higher — the investment in preventing disease entry reflects broader attitudes toward animal welfare that manifest across multiple dimensions of care. Biosecurity investment that prevents disease protects both animal welfare and producer economics, creating aligned incentives that support implementation.
