Spanish officials investigating the recent African swine fever outbreak in the northeastern region are now considering the chance that the disease may have originated from a research facility. Attention has shifted to several local facilities as potential sources.

Outbreak Details and Industry Stakes

Thirteen infections of the virus have been identified in wild boars in the countryside outside the Catalan capital beginning on 28 November. This has led the country – the EU’s biggest exporter of pig products – to rush to control the outbreak before it becomes a significant risk to the nation's €8.8bn-a-year pig meat export industry.

Shifting Theories of Origin

Initially, local officials suspected the outbreak started after a boar ate infected food imported from abroad – possibly a thrown away meat sandwich from a truck driver.

However, the Spanish ministry of agriculture has initiated a different investigation after concluding that the variant of the pathogen detected in the deceased animals in Catalonia is different from the one reported to be circulating in other European countries. Investigative findings indicate the identified virus is rather similar to one found in the country of Georgia in the year 2007.

"The discovery of a virus like the one that was present in that country does not, therefore, exclude the possibility that its source lies in a biological containment laboratory," said the ministry.

Laboratory Connection Examined

The 'Georgia-2007' virus strain is a 'standard' pathogen frequently used in experimental infections in containment facilities to study the virus or to test the effectiveness of treatments, which are presently under development. The report suggests that the virus may not have originated in animals or animal products from any of the nations where the infection is currently present.

Government Response and Review

In response, the regional president of Catalonia stated he had ordered the regional research body to conduct an audit of five laboratories that handle the ASF pathogen within a 20km radius of the affected area.

"We isn’t ruling out any possibilities when it comes to the origin of the incident of this disease, but nor are we confirming any," the official stated. "Every theory remain open. First and foremost, we need to know the facts."

Latest Control Efforts

The agriculture ministry have reported thirteen infections of the disease – all of them in dead feral pigs found within six kilometers of the initial focus. Officials added the remains of 37 more animals discovered in the zone have been analysed, with all showing no infection for the virus. Specialists sent to the thirty-nine swine operations within the 20km radius have found no sign of the illness there. More than one hundred members from the nation's military emergencies unit have additionally been deployed to the region to work alongside police officers and forestry agents.

Worldwide Context of ASF

For a long time endemic to Africa, African swine fever is harmless to people but often fatal to swine. In 2018, the virus emerged in the People's Republic of China, which is has about half of the world’s pig population. By the following year, there were fears that as many as one hundred million pigs had been culled or died. Two years later, the virus was confirmed to be in Germany, home to one of the EU’s largest swine herds.

The Country's Pivotal Position in Meat Production

Spain, which is the European Union's biggest producer of pig meat, sold pork products worth 5.1 billion euros to other European nations last year, and almost 3.7 billion euros of pig-based goods to markets outside the bloc. Official data indicate that Spain slaughtered fifty-eight million pigs in 2021 – an increase of 40% from a decade earlier.
