Spanish officials investigating the ongoing ASF outbreak in the northeastern region are now considering the chance that the disease may have originated from a scientific laboratory. Attention has shifted to several nearby facilities as potential points of origin.

Outbreak Details and Industry Concerns

Thirteen infections of the virus have been confirmed in feral pigs in the rural areas outside Barcelona beginning on 28 November. This has led the country – the European Union's largest pork exporter – to scramble to control the outbreak before it becomes a serious risk to the country's €8.8bn-a-year pig meat export sector.

Shifting Investigative Focus

At first, regional officials suspected the outbreak may have begun after a boar ate contaminated meat products brought in from abroad – possibly a discarded meat sandwich from a truck driver.

However, the Spanish ministry of agriculture has initiated a new line of inquiry after concluding that the strain of the virus found in the deceased animals in the region is not the same as the one known to be present in other European countries. Investigative findings indicate the identified virus is instead akin to one detected in Georgia in 2007.

"The discovery of a strain like the one that circulated in Georgia does not, therefore, exclude the possibility that its source is a high-security facility," stated the agriculture department.

Laboratory Connection Examined

The 'Georgia-2007' virus strain is a 'standard' virus commonly used in experimental infections in secure labs to study the virus or to evaluate the efficacy of vaccines, which are currently under development. The report suggests that the virus might not have originated in livestock or meat products from any of the countries where the disease is currently present.

Government Response and Audit

In reaction, Salvador Illa stated he had ordered the regional research body to conduct an audit of several facilities that work with the ASF pathogen within a 20km radius of the affected area.

"The regional government isn’t ruling out any possibilities when it comes to the origin of the incident of this disease, but neither is it confirming any," he said. "All hypotheses are on the table. Above all, we need to know what happened."

Latest Control Efforts

The agriculture ministry have reported thirteen infections of the disease – all of them in dead feral pigs found within 6km of the first detection site. Officials added the corpses of an additional 37 wild animals discovered in the area have been analysed, with every one testing negative for the virus. Experts dispatched to the 39 swine operations within the 20km radius have detected no sign of the disease there. Over one hundred members from the nation's emergency response forces have also been deployed to the region to assist police officers and wildlife rangers.

Global Background of ASF

Long endemic to the African continent, African swine fever is not dangerous to humans but often deadly to pigs. In the year 2018, the disease emerged in China, which is home to about 50% of the world’s pigs. By the following year, there were fears that as many as one hundred million pigs had been lost. Two years later, the virus was detected to be in the Federal Republic of Germany, a country with one of the European Union's largest swine herds.

Spain's Crucial Role in Pork Exports

Spain, which is the EU’s biggest producer of pig meat, sold pork products worth 5.1 billion euros to other EU countries last year, and nearly 3.7 billion euros of pig-based goods to markets outside Europe. Official data indicate that Spain slaughtered fifty-eight million swine in the year 2021 – an increase of forty percent from a decade earlier.
