Spanish authorities investigating the ongoing ASF incident in Catalonia are now exploring the chance that the virus may have originated from a scientific laboratory. Attention has shifted to five nearby labs as possible points of origin.

Outbreak Details and Industry Concerns

Thirteen cases of the fever have been identified in feral pigs in the rural areas outside Barcelona beginning on 28 November. This has led Spain – the European Union's biggest pork exporter – to scramble to control the outbreak before it escalates into a significant threat to the country's €8.8bn-a-year pig meat export industry.

Shifting Theories of Origin

Initially, local authorities believed the outbreak may have begun after a wild boar consumed contaminated meat products brought in from outside Spain – perhaps a discarded meat sandwich from a truck driver.

However, the national agriculture ministry has opened a different investigation after determining that the strain of the pathogen detected in the deceased animals in the region is not the same as the one reported to be circulating in other European countries. Investigative findings suggest the strain in question is instead similar to one found in the country of Georgia in the year 2007.

"The discovery of a strain like the one that was present in that country does not, therefore, exclude the chance that its source is a biological containment facility," said the ministry.

Research Link Explored

The 'Georgia 2007' viral strain is a 'standard' virus frequently employed in experimental infections in containment facilities to research the virus or to evaluate the effectiveness of treatments, which are currently under development. The report suggests that the outbreak may not have originated in livestock or meat products from any of the countries where the disease is currently present.

Government Response and Audit

In response, Salvador Illa stated he had ordered the regional research body to carry out an audit of several facilities that handle the African swine fever pathogen within a 20-kilometer radius of the outbreak site.

"The regional government isn’t ruling out any scenarios when it comes to the source of the outbreak of this disease, but neither is it confirming any," the official stated. "All hypotheses are open. First and foremost, we need to understand the facts."

Current Control Efforts

The agriculture ministry have reported 13 cases of the virus – all of them in dead wild boar located within six kilometers of the first detection site. They have said the remains of an additional 37 animals found in the area have been analysed, with all showing no infection for the virus. Experts dispatched to the 39 pig farms within the surrounding zone have detected no trace of the illness there. Over 100 personnel from the nation's emergency response forces have also been deployed to the region to work alongside police officers and wildlife rangers.

Worldwide Context of African Swine Fever

For a long time endemic to Africa, African swine fever is harmless to people but frequently fatal to pigs. In 2018, the virus turned up in the People's Republic of China, which is has about 50% of the global pigs. By 2019, there were concerns that as many as one hundred million pigs had been lost. Two years later, the virus was confirmed to be in Germany, home to one of the EU’s largest pig farming industries.

Spain's Crucial Position in Meat Exports

Spain, which is the EU’s largest pork producer, exported pig meat products worth €5.1bn to other European nations in the previous year, and nearly €3.7bn of pork products to markets outside Europe. National data show that Spain slaughtered 58 million swine in the year 2021 – an increase of 40% from a decade earlier.
