Spanish authorities investigating the recent ASF incident in the northeastern region are now exploring the chance that the virus could have originated from a research facility. Attention has shifted to several local facilities as potential points of origin.

Confirmed Cases and Industry Concerns

Thirteen infections of the fever have been confirmed in wild boars in the rural areas outside the Catalan capital since 28 November. This has led Spain – the European Union's biggest pork exporter – to scramble to control the situation before it becomes a serious threat to the country's €8.8bn-a-year pig meat export sector.

Shifting Theories of Origin

Initially, regional officials suspected the outbreak started after a wild boar ate infected meat products imported from abroad – perhaps a thrown away meat sandwich from a truck driver.

However, the national agriculture ministry has initiated a different investigation after determining that the strain of the pathogen found in the dead animals in Catalonia is different from the one known to be circulating in other EU member states. Investigative findings indicate the strain in question is rather similar to one detected in the country of Georgia in 2007.

"The discovery of a strain similar to the one that was present in that country does not, therefore, exclude the possibility that its source lies in a biological containment facility," stated the agriculture department.

Laboratory Link Examined

The 'Georgia 2007' virus strain is a 'reference' pathogen frequently employed in scientific studies in containment facilities to study the virus or to evaluate the effectiveness of treatments, which are currently being developed. The analysis implies that the outbreak may not have started in livestock or animal products from any of the nations where the infection is currently present.

Government Response and Audit

In response, Salvador Illa announced he had instructed the regional research body to conduct an inspection of five facilities that handle the ASF pathogen within a 20km distance of the outbreak site.

"We isn’t ruling out any possibilities when it comes to the origin of the incident of this disease, but neither is it confirming any," he said. "Every theory are on the table. Above all, we need to know the facts."

Current Control Efforts

The agriculture ministry have reported 13 cases of the disease – all of them in deceased feral pigs found within 6km of the initial focus. Officials added the remains of an additional 37 wild animals discovered in the zone have been analysed, with all showing no infection for the virus. Specialists dispatched to the 39 pig farms within the surrounding zone have detected no sign of the disease there. Over one hundred personnel from the nation's military emergencies unit have additionally been deployed to the region to work alongside law enforcement and forestry agents.

Worldwide Background of ASF

Long endemic to the African continent, ASF is harmless to humans but often fatal to pigs. In the year 2018, the virus turned up in China, which is has about 50% of the global pig population. By 2019, there were fears that up to 100 million animals had been lost. Subsequently, the virus was confirmed to be in the Federal Republic of Germany, home to one of the EU’s largest swine herds.

Spain's Pivotal Role in Meat Exports

Spain, which is the EU’s largest producer of pig meat, sold pig meat products worth 5.1 billion euros to other EU countries in the previous year, and nearly €3.7bn of pork products to markets outside the bloc. Official data show that Spain processed fifty-eight million swine in 2021 – an rise of 40% from a decade earlier.
