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 shifted to several local facilities as possible sources.

Confirmed Cases and Industry Stakes

A total of thirteen cases of the fever have been confirmed in feral pigs in the countryside outside Barcelona since 28 November. This has led Spain – the EU’s biggest exporter of pig products – to scramble to contain the outbreak before it escalates into a significant risk to the nation's multi-billion euro pig meat export sector.

Evolving Investigative Focus

Initially, local authorities suspected the outbreak may have begun after a wild boar ate infected food imported from outside Spain – possibly a discarded food item from a truck driver.

However, the national ministry of agriculture has opened a new line of inquiry after concluding that the variant of the pathogen detected in the deceased animals in the region is different from the one known to be present in other EU member states. Investigative findings indicate the identified virus is rather akin to one detected in Georgia in 2007.

"This finding of a virus similar to the one that was present in Georgia does not, therefore, exclude the possibility that its source is a biological containment laboratory," stated the ministry.

Research Link Explored

The 'Georgia-2007' viral strain is a 'standard' virus frequently employed in scientific studies in secure labs to study the virus or to evaluate the effectiveness of vaccines, which are presently under development. The analysis suggests that the virus may not have originated in livestock or meat products from any of the countries where the infection is currently active.

Official Actions and Audit

In reaction, the regional president of Catalonia stated he had ordered the Catalan agrifood research institute to carry out an audit of five laboratories that handle the African swine fever virus within a 20-kilometer distance of the outbreak site.

"The regional government are not excluding any possibilities when it comes to the origin 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 what happened."

Latest Control Efforts

The agriculture ministry have confirmed thirteen infections of the virus – each one in dead wild boar located within 6km of the initial focus. Officials added the corpses of 37 more animals discovered in the area have been tested, with all testing negative for the virus. Specialists sent to the 39 pig farms within the surrounding zone have found no trace of the disease on those farms. Over 100 members from the country's military emergencies unit have additionally been sent to the region to assist police officers and wildlife rangers.

Global Background of ASF

For a long time native to Africa, African swine fever is not dangerous to humans but frequently fatal to pigs. In 2018, the disease turned up in the People's Republic of China, which is home to about 50% of the world’s pig population. By the following year, there were fears that up to 100 million animals had been culled or died. Subsequently, the virus was detected to be in Germany, home to one of the EU’s biggest swine herds.

The Country's Crucial Role in Pork Production

Spain, which is the EU’s largest pork producer, exported pork products worth 5.1 billion euros to other European nations in the previous year, and nearly €3.7bn of pork products to markets outside Europe. National data indicate that the country slaughtered fifty-eight million pigs in 2021 – an rise of 40% from a decade earlier.
