Porcine reproductive and respiratory syndrome (PRRS) has become a global issue, affecting pig farms since around the 1980s. A new type of gene editing hopes to tackle the fatal disease by creating
Also known as “blue-ear pig disease,” PRRS is a viral disease that causes minimal symptoms in some animals while killing others. The leading symptoms include reproductive failure, respiratory distress, and a high rate of mortality for piglets.
PRRS is the “most economically significant disease to affect US swine production since the eradication of classical swine fever,” according to the

“This is a groundbreaking accomplishment in agriculture toward improving animal health, reducing waste, lowering production costs, and potentially reducing antibiotic use on the farm,” write the authors of a new paper on the research. “Further, applying these learnings to eliminate other livestock diseases that are not only harmful to animals (African Swine Fever) but also to humans (swine influenza) would be a major step to benefit consumers, society, and the environment.”
The project hasn’t been without its setbacks, however. Mosaicism saw some gene-edited pigs displaying the desired change to their
Some have also been critical that the solution is missing the point, stating that traditional farming practices will continue to give rise to new pathogen threats.
“Keeping animals crowded together, and in stressful conditions, provides an ideal environment for pathogens to spread and evolve,” Catherine Jadav of Compassion in World Farming said to
