National officials probing the ongoing African swine fever outbreak in Catalonia are now exploring the chance that the virus could have originated from a research facility. Their focus has narrowed to several nearby labs as potential points of origin.

Outbreak Details and Economic Stakes

Thirteen infections of the fever have been confirmed in wild boars in the countryside outside Barcelona since 28 November. This has prompted the country – the European Union's largest pork exporter – to rush to contain the outbreak before it becomes a significant threat to the nation's €8.8bn-a-year pig meat export industry.

Shifting Investigative Focus

Initially, local officials believed the outbreak started after a boar consumed infected meat products imported from abroad – possibly a thrown away meat sandwich from a haulier.

However, the national ministry of agriculture has initiated a new investigation after determining that the strain of the pathogen detected in the deceased boars in the region is different from the one reported to be present in other EU member states. According to a report indicate the strain in question is rather akin to one detected in the country of Georgia in 2007.

"The discovery of a virus like the one that was present in that country does not, therefore, rule out the chance that its origin is a high-security facility," stated the agriculture department.

Laboratory Connection Examined

The 'Georgia 2007' viral strain is a 'reference' virus frequently employed in experimental infections in containment facilities to research the virus or to test the efficacy of vaccines, which are currently being developed. The analysis suggests that the virus might not have originated in livestock or meat products from any of the countries where the infection is currently present.

Official Actions and Audit

In response, the regional president of Catalonia stated he had instructed the Catalan agrifood research institute to carry out an inspection of several laboratories that handle the African swine fever virus within a 20-kilometer distance of the affected area.

"The regional government isn’t ruling out any scenarios when it comes to the origin of the outbreak of African swine fever, but neither is it confirming any," he said. "All hypotheses remain open. First and foremost, we need to understand what happened."

Current Control Measures

The agriculture ministry have confirmed thirteen infections of the disease – all of them in deceased feral pigs found within 6km of the first detection site. They have said the remains of 37 more animals found in the zone have been tested, with all showing no infection for swine fever. Specialists sent to the thirty-nine pig farms within the 20km radius have detected no trace of the disease there. Over 100 personnel from the country's military emergencies unit have additionally been deployed to the area to assist police officers and forestry agents.

Global Background of African Swine Fever

Long native to Africa, African swine fever is not dangerous to people but often fatal to pigs. In the year 2018, the disease emerged in China, which is home to about half of the world’s pig population. By 2019, there were fears that as many as one hundred million animals had been lost. Subsequently, the pathogen was detected to be in the Federal Republic of Germany, home to one of the EU’s largest pig farming industries.

Spain's Pivotal Role in Pork Production

The nation, which is the European Union's largest pork producer, exported pork products worth €5.1bn to other European nations in the previous year, and almost 3.7 billion euros of pig-based goods to markets outside Europe. National data indicate that the country slaughtered 58 million pigs in 2021 – an increase of 40% from a ten years prior.
