Spanish officials investigating 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 local labs as potential points of origin.

Outbreak Details and Economic Concerns

Thirteen cases of the virus have been confirmed in feral pigs in the countryside outside the Catalan capital since 28 November. This has prompted the country – the EU’s biggest exporter of pig products – to rush to control the outbreak before it escalates into a significant threat to the country's multi-billion euro pork export sector.

Shifting Theories of Origin

Initially, local authorities believed the disease started after a boar ate contaminated meat products brought in from abroad – perhaps a thrown away food item from a haulier.

However, the Spanish agriculture ministry has initiated a new investigation after concluding that the variant of the pathogen detected in the deceased animals in Catalonia is not the same as the one reported to be present in other EU member states. Investigative findings indicate the strain in question is instead similar to one detected in the country of Georgia in the year 2007.

"This finding 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 agriculture department.

Research Connection Examined

The 'Georgia-2007' virus strain is a 'reference' pathogen commonly used in experimental infections in containment facilities to research the disease or to evaluate the effectiveness of treatments, which are presently under development. The analysis suggests that the virus may not have started in animals or animal products from any of the countries where the disease is currently present.

Government Actions and Review

In response, Salvador Illa announced he had instructed the Catalan agrifood research institute to conduct an audit of five facilities that handle the African swine fever pathogen within a 20km radius of the affected area.

"We isn’t ruling out any scenarios when it comes to the origin of the incident of African swine fever, but nor are we confirming any," the official stated. "All hypotheses remain on the table. Above all, we need to understand the facts."

Current Containment Measures

The agriculture ministry have reported 13 cases of the disease – each one in deceased feral pigs located within 6km of the initial focus. Officials added the remains of an additional 37 wild animals discovered in the zone have been tested, with every one testing negative for the virus. Specialists dispatched to the 39 pig farms within the 20km radius have detected no sign of the disease on those farms. More than one hundred personnel from the nation's emergency response forces have also been deployed to the area to assist police officers and forestry agents.

Global Background of African Swine Fever

For a long time native to Africa, African swine fever is not dangerous to people but often deadly to swine. In 2018, the virus turned up in the People's Republic of China, which is home to about half of the world’s pig population. By the following year, there were fears that up to 100 million pigs had been culled or died. Subsequently, the pathogen was confirmed to be in Germany, a country with one of the European Union's largest pig farming industries.

The Country's Crucial Position in Meat Production

The nation, which is the EU’s biggest producer of pig meat, sold pig meat products worth €5.1bn to other EU countries in the previous year, and nearly €3.7bn of pork products to markets outside Europe. National data indicate that the country slaughtered 58 million swine in the year 2021 – an increase of forty percent from a ten years prior.
