National authorities probing the recent ASF incident in Catalonia are now considering the chance that the virus could have escaped from a research facility. Attention has narrowed to five local labs as potential sources.

Confirmed Cases and Industry Stakes

A total of thirteen infections of the fever have been confirmed in wild boars in the rural areas outside the Catalan capital beginning on 28 November. This has prompted Spain – the European Union's largest exporter of pig products – to scramble to control the situation before it escalates into a serious threat to the country's multi-billion euro pig meat export industry.

Evolving Theories of Origin

At first, regional officials believed the disease started after a wild boar ate contaminated meat products brought in from outside Spain – possibly a thrown away food item from a haulier.

However, the national ministry of agriculture has opened a new line of inquiry after concluding that the strain of the virus found in the dead boars in Catalonia is different from the one known to be circulating in other European countries. According to a report suggest the strain in question is instead akin to one found in the country of Georgia in 2007.

"This finding of a virus similar to the one that was present in Georgia does not, therefore, exclude the chance that its origin is a high-security laboratory," stated the ministry.

Laboratory Connection Examined

The 'Georgia 2007' virus strain is a 'standard' virus frequently employed in experimental infections in containment facilities to study the disease or to test the effectiveness of treatments, which are presently under development. The report implies that the outbreak may not have originated in livestock or meat products from any of the countries where the infection is currently active.

Government Response and Audit

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

"We are not excluding any scenarios when it comes to the origin of the outbreak of this disease, but neither is it confirming any," the official stated. "Every theory are on the table. Above all, we need to know what happened."

Current Containment Efforts

The authorities have reported 13 cases of the disease – all of them in deceased feral pigs found within 6km of the first detection site. Officials added the corpses of an additional 37 wild animals found in the zone have been tested, with every one showing no infection for swine fever. Specialists dispatched to the 39 pig farms within the surrounding zone have found no trace of the illness on those farms. Over one hundred personnel from the country's military emergencies unit have additionally been sent to the area to assist police officers and forestry agents.

Worldwide Context of ASF

For a long time native to Africa, African swine fever is harmless to humans but often deadly to pigs. In the year 2018, the virus emerged in the People's Republic of China, which is has about half of the world’s pig population. By the following year, there were concerns that as many as 100 million pigs had been culled or died. Two years later, the virus was detected to be in the Federal Republic of Germany, home to one of the EU’s biggest swine herds.

Spain's Crucial Position in Pork Production

Spain, which is the EU’s largest pork producer, exported pork products worth €5.1bn to other EU countries in the previous year, and nearly 3.7 billion euros of pork products to destinations outside the bloc. Official statistics show that the country slaughtered 58 million pigs in the year 2021 – an rise of 40% from a decade earlier.
