Spanish officials investigating the ongoing African swine fever outbreak in the northeastern region are now considering the possibility that the disease could have originated from a scientific laboratory. Their focus has shifted to several local facilities as possible sources.

Outbreak Details and Economic Stakes

A total of thirteen cases of the fever have been confirmed in feral pigs in the countryside outside the Catalan capital beginning on 28 November. This has led Spain – the EU’s largest pork exporter – to scramble to contain the situation before it escalates into a serious threat to the country's €8.8bn-a-year pork export industry.

Shifting Investigative Focus

At first, regional authorities believed the disease started after a wild boar ate infected food imported from outside Spain – perhaps a thrown away meat sandwich from a haulier.

However, the national agriculture ministry has opened a new investigation after concluding that the variant of the pathogen found in the dead boars in Catalonia is not the same as the one reported to be circulating in other European countries. Investigative findings indicate the strain in question is instead akin to one detected in the country of Georgia in the year 2007.

"The discovery of a strain similar to the one that was present in Georgia does not, therefore, exclude the chance that its source is a biological containment laboratory," said the agriculture department.

Laboratory Link Examined

The 'Georgia-2007' virus strain is a 'standard' virus frequently used in experimental infections in containment facilities to study the disease or to test the effectiveness of treatments, which are currently being developed. The analysis suggests that the virus may not have originated in animals or meat products from any of the nations where the infection is currently active.

Government Response and Audit

In reaction, Salvador Illa stated he had instructed the regional research body to conduct an audit of several facilities that work with the ASF pathogen within a 20-kilometer radius of the affected area.

"The regional government isn’t ruling out any possibilities when it comes to the source of the outbreak of this disease, but neither is it confirming any," the official stated. "Every theory remain on the table. Above all, we need to understand the facts."

Current Containment Measures

The agriculture ministry have reported 13 cases of the virus – all of them in dead wild boar located within 6km of the first detection site. They have said the remains of 37 more animals found in the area have been analysed, with all testing negative for the virus. Experts dispatched to the 39 swine operations within the 20km radius have detected no trace of the disease there. More than one hundred members from the nation's military emergencies unit have also been deployed to the area to assist police officers and forestry agents.

Worldwide Context of ASF

Long native to the African continent, ASF is harmless to humans but often fatal to pigs. In 2018, the disease turned up in China, which is home to about half of the world’s pig population. 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 the Federal Republic of Germany, a country with one of the EU’s biggest swine herds.

Spain's Pivotal Role in Meat Production

The nation, which is the European Union's largest producer of pig meat, sold pork products worth €5.1bn to other EU countries last year, and almost 3.7 billion euros of pig-based goods to markets outside Europe. National data show that Spain processed fifty-eight million pigs in 2021 – an rise of forty percent from a decade earlier.
