The recent African swine fever outbreak in Spain has sparked a heated debate, with officials now considering a controversial theory: the disease may have originated from a research lab. This outbreak, which has already caused significant concern among Spanish authorities, has led to a thorough investigation into five nearby laboratories as potential sources.
Since November 28, thirteen cases of the fever have been confirmed in wild boars near Barcelona, prompting Spain to take immediate action to prevent a major threat to its pork export industry, valued at €8.8 billion annually. Initially, the regional authorities suspected that the disease spread after a wild boar consumed contaminated food, possibly a discarded meat sandwich brought in from outside Spain.
However, a recent development has shifted the focus. Spain's agriculture ministry has discovered that the virus strain found in the dead boars in Catalonia is distinct from the one reported in other EU member states, resembling a strain detected in Georgia in 2007. This revelation has raised suspicions about the possibility of a biological containment facility being the source.
The ministry's statement on Friday emphasized the potential connection to a 'reference' virus used in experimental infections within containment facilities. This virus, known as the 'Georgia 2007' strain, is frequently employed to study the virus or evaluate vaccine efficacy, which are currently under development. The report suggests that the virus may not have originated from animals or animal products in affected countries.
Catalonia's regional president, Salvador Illa, ordered an audit of five facilities within a 20km radius of the outbreak site, which work with the African swine fever virus. He emphasized that all hypotheses remain open, prioritizing the need to understand the outbreak's origin.
The agriculture ministry has confirmed 13 cases of the virus, all found in dead wild boars within a 6km radius. They have analyzed the remains of 37 additional wild animals in the area, all of which tested negative for swine fever. Experts have also inspected 39 pig farms within a 20km radius, finding no signs of the illness.
Spain, the EU's largest pork producer, exported pig meat products worth €5.1 billion to other EU countries and almost €3.7 billion to non-EU markets in the previous year. The country slaughtered 58 million pigs in 2021, a 40% increase from a decade earlier.
This outbreak highlights the ongoing challenge of managing African swine fever, a disease long endemic to Africa but now spreading to other regions. While harmless to humans, it poses a significant threat to pigs, with concerns rising about potential losses in the pork industry.
