Spanish officials probing the recent ASF incident in the northeastern region are now exploring the chance that the virus could have originated from a scientific laboratory. Attention has shifted to five local facilities as potential points of origin.

Outbreak Details and Economic Stakes

Thirteen cases of the virus have been identified in feral pigs in the countryside outside the Catalan capital beginning on 28 November. This has prompted the country – the EU’s biggest exporter of pig products – to scramble to contain the situation before it escalates into a serious risk to the nation's multi-billion euro pork export sector.

Shifting Theories of Origin

At first, local officials believed the disease started after a boar consumed contaminated food imported from outside Spain – possibly a thrown away meat sandwich from a haulier.

However, the national agriculture ministry has initiated a different line of inquiry after determining that the strain of the pathogen found in the dead animals in the region is not the same as the one reported to be circulating in other European countries. Investigative findings suggest the strain in question is rather similar to one found in Georgia in 2007.

"The discovery of a virus similar to the one that was present in that country does not, therefore, rule out the chance that its source is a biological containment laboratory," stated the ministry.

Laboratory Link Explored

The 'Georgia 2007' viral strain is a 'reference' virus frequently used in scientific studies in containment facilities to study the disease or to test the efficacy of vaccines, which are currently being developed. The report suggests that the virus may not have started in animals or animal products from any of the countries where the disease is currently active.

Government Actions and Audit

In reaction, the regional president of Catalonia stated he had ordered the Catalan agrifood research institute to carry out an inspection of several laboratories that work with the ASF pathogen within a 20-kilometer radius of the affected area.

"We are not excluding any scenarios when it comes to the source of the incident of this disease, but neither is it confirming any," he said. "All hypotheses are on the table. Above all, we need to understand what happened."

Current Containment Efforts

The authorities have reported 13 cases of the disease – each one in deceased wild boar located within 6km of the initial focus. They have said the corpses of an additional 37 wild animals found in the zone have been analysed, with every one testing negative for the virus. Experts dispatched to the thirty-nine pig farms within the 20km radius have found no sign of the illness on those farms. More than 100 members from the country's military emergencies unit have additionally been sent to the area to assist police officers and wildlife rangers.

Worldwide Background of African Swine Fever

For a long time native to the African continent, African swine fever is harmless to people but often deadly to pigs. In 2018, the disease turned up in China, which is home to about 50% of the world’s pig population. By 2019, there were fears that up to 100 million pigs had been lost. Two years later, the pathogen was detected to be in the Federal Republic of Germany, home to one of the European Union's largest swine herds.

Spain's Crucial Role in Meat Production

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