Spanish authorities investigating the recent African swine fever incident in Catalonia are now exploring the chance that the virus may have escaped from a scientific laboratory. Their focus has shifted to five nearby facilities as possible points of origin.

Confirmed Cases and Industry Concerns

A total of thirteen cases of the virus have been confirmed in feral pigs in the rural areas outside Barcelona since 28 November. This has prompted the country – the EU’s biggest pork exporter – to rush to control the situation before it escalates into a serious threat to the nation's multi-billion euro pork export sector.

Evolving Theories of Origin

At first, regional officials believed the outbreak may have begun after a boar ate contaminated food imported from outside Spain – perhaps a thrown away food item from a truck driver.

However, the Spanish agriculture ministry has initiated a new line of inquiry after determining that the variant of the pathogen found in the deceased boars in Catalonia is different from the one known to be present in other EU member states. Investigative findings suggest the strain in question is rather similar to one found in Georgia in 2007.

"The discovery of a virus like the one that circulated in Georgia does not, therefore, rule out the chance that its source lies in a biological containment facility," stated the agriculture department.

Laboratory Link Examined

The 'Georgia-2007' virus strain is a 'reference' virus frequently used in experimental infections in containment facilities to study the virus or to test the efficacy of treatments, which are presently under development. The analysis suggests that the outbreak might not have started in animals or meat products from any of the countries where the disease is currently active.

Official Actions and Audit

In reaction, Salvador Illa announced he had instructed the Catalan agrifood research institute to conduct an inspection of several facilities that work with the African swine fever pathogen within a 20km distance of the outbreak site.

"The regional government isn’t ruling out any possibilities when it comes to the source of the outbreak of African swine fever, but neither is it confirming any," the official stated. "All hypotheses are open. Above all, we need to know the facts."

Latest Control Efforts

The agriculture ministry have confirmed thirteen infections of the disease – each one in dead wild boar found within 6km of the initial focus. Officials added the corpses of 37 more wild animals discovered in the zone have been tested, with all testing negative for the virus. Specialists dispatched to the thirty-nine swine operations within the 20km radius have detected no trace of the disease there. Over 100 members from the nation's emergency response forces have additionally been sent to the region to work alongside law enforcement and wildlife rangers.

Global Background of African Swine Fever

Long native to Africa, African swine fever is not dangerous to people but frequently fatal to pigs. In the year 2018, the disease emerged in China, which is has about half of the global pigs. By the following year, there were concerns that up to 100 million pigs had been lost. Two years later, the virus was confirmed to be in Germany, a country with one of the EU’s largest swine herds.

The Country's Crucial Position in Pork Exports

Spain, which is the EU’s largest pork producer, sold pig meat products worth 5.1 billion euros to other EU countries last year, and almost 3.7 billion euros of pork products to markets outside the bloc. Official statistics show that Spain processed 58 million swine in 2021 – an increase of forty percent from a decade earlier.
