Spanish officials probing the recent African swine fever incident in Catalonia are now exploring the chance that the disease could have originated from a scientific laboratory. Attention has narrowed to several nearby facilities as potential sources.

Outbreak Details and Industry Stakes

A total of thirteen infections of the virus have been identified in feral pigs in the countryside outside Barcelona beginning on 28 November. This has led the country – the EU’s largest pork exporter – to scramble to control the outbreak before it escalates into a significant threat to the country's €8.8bn-a-year pork export industry.

Evolving Investigative Focus

At first, local authorities suspected the outbreak may have begun after a wild boar ate contaminated food imported from outside Spain – perhaps a thrown away meat sandwich from a haulier.

However, the national ministry of agriculture has initiated a different investigation after concluding that the strain of the pathogen detected in the deceased animals in Catalonia is different from the one reported to be present in other European countries. Investigative findings indicate the identified virus is instead similar to one detected in Georgia in the year 2007.

"The discovery of a strain similar to the one that circulated in Georgia does not, therefore, exclude the possibility that its origin is a high-security facility," said the ministry.

Research Connection Examined

The 'Georgia 2007' virus strain is a 'standard' virus commonly used in scientific studies in containment facilities to research the disease or to evaluate the effectiveness of vaccines, which are currently being developed. The report implies that the outbreak might not have started in animals or animal products from any of the countries where the infection is currently present.

Government Actions and Review

In reaction, the regional president of Catalonia announced he had instructed the Catalan agrifood research institute to conduct an audit of several laboratories that handle the ASF virus within a 20km radius of the outbreak site.

"We are not excluding any scenarios when it comes to the source of the incident of this disease, but neither is it confirming any," the official stated. "All hypotheses remain open. First and foremost, we need to understand the facts."

Current Containment Measures

The agriculture ministry have reported 13 cases of the virus – each one in dead wild boar found within 6km of the initial focus. Officials added the remains of 37 more wild animals discovered in the zone have been analysed, with every one showing no infection for the virus. Experts dispatched to the 39 swine operations within the 20km radius have detected no sign of the illness there. Over one hundred personnel from the nation's emergency response forces have also been deployed to the region to work alongside law enforcement and forestry agents.

Global Context of African Swine Fever

For a long time endemic to the African continent, ASF is harmless to people but often fatal to pigs. In 2018, the disease emerged in China, which is has about half of the global pigs. By the following year, there were fears that up to one hundred million pigs had been lost. Subsequently, the pathogen was confirmed to be in Germany, a country with one of the European Union's biggest swine herds.

The Country's Crucial Role in Meat Production

The nation, which is the European Union's biggest producer of pig meat, exported pork products worth 5.1 billion euros to other European nations last year, and nearly €3.7bn of pork products to markets outside the bloc. Official data indicate that Spain slaughtered fifty-eight million pigs in 2021 – an increase of 40% from a decade earlier.
