National authorities investigating the ongoing African swine fever outbreak in the northeastern region are now considering the possibility that the disease may have originated from a research facility. Attention has narrowed to several local labs as possible sources.

Outbreak Details and Industry Stakes

A total of thirteen cases of the fever have been confirmed in feral pigs in the rural areas outside the Catalan capital beginning on 28 November. This has prompted the country – the European Union's largest pork exporter – to scramble to contain the outbreak before it escalates into a serious risk to the nation's multi-billion euro pork export industry.

Evolving Theories of Origin

At first, regional officials believed the disease started after a wild boar ate infected meat products imported from outside Spain – perhaps a discarded meat sandwich from a truck driver.

However, the Spanish ministry of agriculture has initiated a new investigation after determining that the variant of the pathogen found in the deceased animals in Catalonia is different from the one known to be circulating in other European countries. According to a report suggest the identified virus is instead akin to one detected in Georgia in the year 2007.

"The discovery of a virus similar to the one that was present in Georgia does not, therefore, exclude the possibility that its source lies in a high-security laboratory," stated the agriculture department.

Research Link Examined

The 'Georgia 2007' virus strain is a 'standard' virus commonly employed in scientific studies in containment facilities to research the virus or to evaluate the efficacy of vaccines, which are presently under development. The analysis suggests that the virus may not have started in livestock or meat products from any of the nations where the disease is currently present.

Official Response and Review

In response, the regional president of Catalonia announced he had ordered the Catalan agrifood research institute to conduct an audit of several laboratories that work with the ASF virus within a 20-kilometer radius of the outbreak site.

"We are not excluding any possibilities when it comes to the origin of the incident of this disease, but neither is it confirming any," the official stated. "All hypotheses remain on the table. Above all, we need to know the facts."

Latest Containment Measures

The agriculture ministry have reported 13 cases of the disease – each one in dead feral pigs located within six kilometers of the first detection site. Officials added the corpses of an additional 37 animals discovered in the zone have been tested, with every one showing no infection for swine fever. Specialists sent to the thirty-nine swine operations within the surrounding zone have detected no sign of the illness there. More than one hundred members from the country's military emergencies unit have additionally been deployed to the region to work alongside law enforcement and wildlife rangers.

Global Background of African Swine Fever

For a long time native to the African continent, African swine fever is harmless to humans but often deadly to swine. In 2018, the disease emerged in the People's Republic of China, which is home to about half of the world’s pigs. By 2019, there were concerns that up to one hundred million pigs had been lost. Subsequently, the virus was confirmed to be in the Federal Republic of Germany, home to one of the EU’s biggest pig farming industries.

The Country's Pivotal Position in Meat Exports

Spain, which is the EU’s biggest pork producer, sold pig meat 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 data indicate that the country slaughtered 58 million pigs in 2021 – an increase of 40% from a decade earlier.
