National authorities investigating the ongoing ASF incident in the northeastern region are now exploring the possibility that the disease could have escaped from a scientific laboratory. Their focus has shifted to several nearby facilities as possible sources.

Confirmed Cases and Economic Stakes

Thirteen infections of the fever have been identified in wild boars in the countryside outside the Catalan capital beginning on 28 November. This has prompted the country – the EU’s biggest exporter of pig products – to scramble to contain the situation before it escalates into a significant risk to the country's €8.8bn-a-year pork export sector.

Evolving Investigative Focus

At first, local officials believed the outbreak may have begun after a boar ate contaminated meat products brought in from abroad – possibly a thrown away food item from a truck driver.

However, the national ministry of agriculture has opened a different investigation after concluding that the strain of the virus detected in the deceased boars in Catalonia is different from the one reported to be present in other EU member states. According to a report indicate the strain in question is instead akin to one detected in Georgia in the year 2007.

"This finding of a virus similar to the one that circulated in Georgia does not, therefore, exclude the possibility that its source lies in a biological containment laboratory," stated the agriculture department.

Research Connection Explored

The 'Georgia-2007' viral strain is a 'standard' pathogen commonly employed in scientific studies in containment facilities to research the disease or to test the efficacy of vaccines, which are presently under development. The report suggests that the outbreak might not have started in animals or meat products from any of the nations where the infection is currently present.

Official Response and Review

In response, the regional president of Catalonia announced he had instructed the regional research body to carry out an audit of several laboratories that work with the African swine fever pathogen within a 20km distance of the affected area.

"The regional government are not excluding any possibilities when it comes to the source of the outbreak of African swine fever, but neither is it confirming any," the official stated. "Every theory remain on the table. First and foremost, we need to understand what happened."

Latest Containment Efforts

The agriculture ministry have reported thirteen infections of the disease – each one in deceased feral pigs located within 6km of the first detection site. They have said the corpses of 37 more animals found in the area have been analysed, with every one testing negative for swine fever. Specialists dispatched to the 39 swine operations within the 20km radius have detected no sign of the illness on those farms. More than one hundred personnel from the country's military emergencies unit have additionally been sent to the area to assist law enforcement and forestry agents.

Global Background of ASF

For a long time endemic to the African continent, ASF is not dangerous to people but often fatal to swine. In the year 2018, the disease turned up in the People's Republic of China, which is has about half of the global pig population. By 2019, there were fears that up to 100 million animals had been culled or died. Subsequently, the pathogen was confirmed to be in the Federal Republic of Germany, home to one of the European Union's largest pig farming industries.

Spain's Crucial Role in Meat Production

The nation, which is the EU’s largest pork producer, sold pig meat products worth 5.1 billion euros to other EU countries last year, and nearly 3.7 billion euros of pork products to destinations outside Europe. Official data indicate that Spain processed fifty-eight million pigs in 2021 – an increase of 40% from a decade earlier.
