ASF Incident in Spanish Territory: Investigators Probe Potential Research Lab Leak

National authorities investigating the recent African swine fever incident in Catalonia are now considering the chance that the disease may have escaped from a research facility. Their focus has narrowed to five nearby labs as potential points of origin.

Outbreak Details and Industry Stakes

Thirteen cases of the fever have been identified in feral pigs in the rural areas outside the Catalan capital since 28 November. This has led Spain – the European Union's biggest pork exporter – to rush to control the outbreak before it becomes a serious risk to the country's €8.8bn-a-year pig meat export industry.

Evolving Investigative Focus

Initially, regional authorities suspected the disease may have begun after a boar ate infected food imported from abroad – perhaps a thrown away meat sandwich from a haulier.

However, the Spanish agriculture ministry has opened a different investigation after concluding that the variant of the virus found in the deceased boars in Catalonia is not the same as the one reported to be present in other EU member states. Investigative findings suggest the identified virus is instead akin to one found in the country of Georgia in 2007.

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

Laboratory Link Examined

The 'Georgia-2007' virus strain is a 'standard' virus commonly used in scientific studies in secure labs to study the disease or to test the effectiveness of vaccines, which are presently being developed. The report implies that the virus might not have originated in animals or meat products from any of the nations where the disease is currently active.

Government Response and Audit

In reaction, the regional president of Catalonia stated he had ordered the Catalan agrifood research institute to carry out an inspection of five facilities that handle the ASF virus within a 20km radius of the affected area.

"The regional government are not excluding any scenarios when it comes to the source of the outbreak of this disease, but neither is it confirming any," he said. "Every theory remain open. First and foremost, we need to understand the facts."

Latest Containment Measures

The authorities have confirmed thirteen infections of the disease – all of them in dead feral pigs located within six kilometers of the initial focus. Officials added the corpses of an additional 37 wild animals found in the area have been tested, with every one showing no infection for swine fever. Experts dispatched to the thirty-nine pig farms within the surrounding zone have found no trace of the illness on those farms. More than 100 members from the nation's military emergencies unit have also been sent to the region to work alongside law enforcement and forestry agents.

Worldwide Background of ASF

For a long time endemic to the African continent, ASF is not dangerous to people but frequently fatal to pigs. In 2018, the disease turned up in the People's Republic of China, which is home to about half of the global pigs. By the following year, there were fears that up to one hundred million animals had been lost. Two years later, the virus was confirmed to be in the Federal Republic of Germany, a country with one of the EU’s biggest pig farming industries.

Spain's Crucial Role in Meat Production

Spain, which is the EU’s biggest pork producer, exported pig meat products worth €5.1bn to other EU countries last year, and nearly €3.7bn of pig-based goods to destinations outside Europe. National data indicate that the country slaughtered 58 million swine in 2021 – an rise of 40% from a ten years prior.
