Spanish authorities investigating the recent African swine fever outbreak in Catalonia are now considering the possibility that the virus may have originated from a research facility. Attention has narrowed to five nearby labs as possible sources.

Confirmed Cases and Industry Stakes

Thirteen infections of the virus have been identified in wild boars in the rural areas outside Barcelona beginning on 28 November. This has led Spain – the European Union's largest exporter of pig products – to scramble to control the situation before it escalates into a significant risk to the country's €8.8bn-a-year pig meat export sector.

Shifting Theories of Origin

Initially, regional officials suspected the outbreak started after a boar ate infected meat products brought in from abroad – perhaps a thrown away meat sandwich from a truck driver.

However, the Spanish agriculture ministry has opened a new investigation after concluding that the strain of the virus detected in the deceased boars in Catalonia is not the same as the one known to be present in other European countries. Investigative findings suggest the identified virus is instead akin to one found in Georgia in the year 2007.

"The discovery of a virus like the one that circulated in Georgia does not, therefore, rule out the possibility that its origin lies in a high-security facility," said the agriculture department.

Laboratory Link Examined

The 'Georgia 2007' viral strain is a 'reference' virus commonly used in experimental infections in containment facilities to research the virus or to evaluate the effectiveness of vaccines, which are currently being developed. The analysis suggests that the virus may not have originated in livestock or animal products from any of the countries where the disease is currently active.

Government Response and Audit

In response, the regional president of Catalonia announced he had ordered the Catalan agrifood research institute to conduct an inspection of five facilities that work with the African swine fever virus within a 20-kilometer radius of the outbreak site.

"We are not excluding any possibilities when it comes to the origin of the outbreak of this disease, but nor are we confirming any," he said. "Every theory remain open. Above all, we need to understand the facts."

Current Control Measures

The authorities have reported thirteen infections of the virus – each one in deceased feral pigs found within six kilometers of the initial focus. Officials added the corpses of 37 more wild animals found in the zone have been analysed, with every one showing no infection for the virus. Specialists dispatched to the thirty-nine swine operations within the surrounding zone have found no trace of the illness there. More than one hundred personnel from the nation's military emergencies unit have also been sent to the region to assist police officers and wildlife rangers.

Worldwide Background of African Swine Fever

For a long time endemic to the African continent, African swine fever is not dangerous to people but frequently deadly to swine. In 2018, the disease emerged in China, which is has about half of the world’s pigs. By 2019, there were fears that up to one hundred million animals had been lost. Subsequently, the pathogen was detected to be in the Federal Republic of Germany, a country with one of the European Union's biggest pig farming industries.

The Country's Crucial Role in Meat Exports

The nation, which is the EU’s biggest pork producer, sold pig meat products worth 5.1 billion euros to other EU countries last year, and almost 3.7 billion euros of pig-based goods to markets outside Europe. National statistics show that the country slaughtered 58 million swine in 2021 – an increase of forty percent from a ten years prior.
