Spanish authorities investigating the ongoing ASF outbreak in the northeastern region are now exploring the chance that the disease could have originated from a scientific laboratory. Their focus has shifted to several nearby facilities as possible sources.

Outbreak Details and Economic Stakes

A total of 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 Spain – the EU’s biggest exporter of pig products – to rush to control the outbreak before it becomes a significant threat to the country's multi-billion euro pig meat export industry.

Evolving Theories of Origin

Initially, regional officials suspected the disease may have begun after a boar consumed contaminated meat products imported from outside Spain – possibly a discarded meat sandwich from a truck driver.

However, the national ministry of agriculture has initiated a different line of inquiry after concluding that the strain of the virus found in the dead animals in Catalonia is different from the one known to be present in other EU member states. According to a report indicate the strain in question is instead akin to one detected in Georgia in 2007.

"This finding of a strain like the one that circulated in that country does not, therefore, exclude the chance that its source lies in a biological containment laboratory," said the agriculture department.

Research Link Explored

The 'Georgia-2007' viral strain is a 'reference' pathogen frequently employed in experimental infections in secure labs to research the virus or to test the effectiveness of treatments, which are presently under development. The analysis suggests that the outbreak might not have originated in livestock or meat products from any of the nations where the disease is currently active.

Official Actions and Audit

In reaction, the regional president of Catalonia stated he had instructed the Catalan agrifood research institute to conduct an inspection of several facilities that work with the African swine fever virus 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 nor are we confirming any," the official stated. "Every theory remain on the table. Above all, we need to understand the facts."

Latest Control Efforts

The authorities have confirmed 13 cases of the virus – all of them in dead wild boar located within 6km of the first detection site. They have said the remains of 37 more wild animals discovered in the zone have been tested, with all testing negative for swine fever. Specialists dispatched to the thirty-nine swine operations within the surrounding zone have found no sign of the illness there. Over 100 members from the nation's emergency response forces have also been deployed to the area to assist law enforcement and wildlife rangers.

Global Background of ASF

Long endemic to the African continent, African swine fever is not dangerous to people but often fatal to swine. In 2018, the virus emerged in the People's Republic of China, which is home to about 50% of the world’s pigs. By 2019, there were concerns that up to one hundred million animals had been lost. Subsequently, the virus was detected to be in the Federal Republic of Germany, home to one of the EU’s biggest pig farming industries.

The Country's Pivotal Role in Meat Exports

Spain, which is the EU’s largest pork producer, sold pig meat products worth €5.1bn to other EU countries in the previous year, and nearly €3.7bn of pig-based goods to destinations outside Europe. Official data show that Spain slaughtered 58 million pigs in the year 2021 – an increase of forty percent from a decade earlier.
