African Swine Fever Outbreak in Spain: Investigators Probe Possible Laboratory Leak

Spanish authorities investigating the recent ASF outbreak in Catalonia are now exploring the possibility that the disease may have originated from a research facility. Attention has shifted to several local facilities as possible points of origin.

Outbreak Details and Industry Stakes

A total of thirteen infections of the virus have been confirmed in wild boars in the rural areas outside Barcelona since 28 November. This has led Spain – the EU’s largest pork exporter – to scramble to contain the outbreak before it escalates into a significant risk to the nation's €8.8bn-a-year pork export sector.

Shifting Theories of Origin

At first, local authorities believed the disease may have begun after a wild boar ate infected food imported from abroad – possibly a thrown away food item from a haulier.

However, the Spanish ministry of agriculture has initiated a new line of inquiry after concluding that the variant of the pathogen detected in the deceased animals in the region is different from the one known to be circulating in other EU member states. According to a report suggest the identified virus is instead akin to one detected in the country of Georgia in 2007.

"This finding of a virus similar to the one that was present in Georgia does not, therefore, exclude the chance that its source is a high-security laboratory," stated the ministry.

Research Link Examined

The 'Georgia 2007' virus strain is a 'reference' virus commonly used in experimental infections in containment facilities to research the virus or to evaluate the efficacy of vaccines, which are currently under development. The analysis implies that the outbreak might not have started in livestock or animal products from any of the nations where the infection is currently present.

Official Actions and Review

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

"We are not excluding any possibilities when it comes to the origin of the incident of African swine fever, but nor are we confirming any," he said. "All hypotheses are on the table. First and foremost, we need to know what happened."

Current Containment Measures

The authorities have reported 13 cases of the disease – all of them in dead feral pigs found within six kilometers of the initial focus. They have said the corpses of an additional 37 wild animals discovered in the area have been analysed, with all testing negative for swine fever. Experts sent to the 39 pig farms within the 20km radius have found no sign of the illness there. More than one hundred members from the country's military emergencies unit have also been deployed to the area to assist police officers and wildlife rangers.

Global Background of ASF

Long native to Africa, African swine fever is not dangerous to humans but frequently deadly to pigs. In the year 2018, the virus turned up in China, which is home to about 50% of the global pigs. By 2019, there were concerns that up to one hundred million animals had been lost. Two years later, the virus was detected to be in Germany, home to one of the European Union's biggest swine herds.

Spain'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 almost €3.7bn of pig-based goods to destinations outside Europe. National statistics indicate that Spain slaughtered fifty-eight million swine in 2021 – an increase of forty percent from a decade earlier.
