Barcelona's Swine Fever: Lab Leak Under Scrutiny

Spain's Agriculture Ministry investigates a potential lab leak after swine fever hits Barcelona. 13 wild boars tested positive. The virus strain, linked to one from Georgia in 2007, raises concerns about its source. Previously, a food contamination theory was considered.

Spain's Agriculture Ministry has launched an investigation to determine if a swine fever outbreak in Barcelona originated from a laboratory leak. The country, which stands as the EU's leading pork producer, seeks to calm trading partners following the discovery of the virus in 13 wild boars in the city's outskirts.

The virus, harmless to humans but potentially lethal to pigs and wild boars, has been traced to a strain similar to one identified in Georgia in 2007, as revealed by genome sequencing conducted in a Madrid laboratory. This strain is commonly used in research and vaccine development, differing from other European strains.

A report highlights the possibility of the virus originating in a containment facility, contrary to initial suspicions that the infection spread from contaminated food consumed by a wild boar. Known as the Georgia 2007 strain, the virus spread to regions including Armenia and China, where it significantly impacted pig production.
