Swine fever outbreak investigations in Spain have taken a dramatic new turn.
The Ministry of Agriculture has opened a formal inquiry into whether the African swine fever virus detected in wild boar in Catalonia may have originated from a laboratory.

This follows analysis showing the strain is unlike those currently circulating in neighbouring countries.
According to a European Union laboratory report, the virus found in Collserola is genetically distinct. It closely matches a strain that circulated in Georgia back in 2007, which is commonly used in experimental infections at research centres. Consequently, officials now suspect a potential breach from a high-containment biological facility.
Swine Fever Outbreak Investigation Uncovers Anomalies
The ministry has communicated its findings to the Civil Guard’s Nature Protection Service. Furthermore, it has requested the Catalan police to conduct a parallel investigation into the virus sequencing. “Viruses, under natural conditions, undergo changes in their genome when they spread through infection cycles in animals,” the ministry stated. “Finding a virus similar to the one that circulated in Georgia does not exclude the possibility that its origin could be in a biological containment facility.”
This development represents a significant shift in the official hypothesis. Previously, authorities believed the outbreak likely stemmed from infected animals or animal products entering the region. The EU report, however, suggests this may not be the case.
All viruses currently circulating in EU member states belong to genetic groups 2-28. The Collserola outbreak virus, conversely, belongs to group 29, which is remarkably similar to the old Georgian group 1 strain. This anomaly has raised serious questions about its provenance.
Authorities Urge Caution Amidst Growing Scrutiny
Catalan Minister of Agriculture, Òscar Ordeig, has urged caution. He described the EU report as inconclusive and asked for patience. “Let the scientists work,” he stated. “We will share every new development immediately, without filters.”
When questioned about the nearby Centre for Animal Health Research, which has studied the virus for two decades, Minister Ordeig was circumspect. The government, he said, “does not rule anything out nor affirm anything.” The centre’s head of high biocontainment, Xavier Abad, has previously stated they found no incidents in their recent activity logs, while acknowledging that “zero risk does not exist.”
The investigation’s focus on a potential laboratory origin adds a complex new dimension to managing the outbreak. It also highlights the stringent security protocols required for handling dangerous animal pathogens. This situation follows other local challenges, such as the recent struggles faced by El Raval businesses with public order, underscoring the varied pressures on Catalonia’s authorities.
As the scientific and criminal investigations proceed, the priority remains containing the virus to protect Catalonia’s valuable pork industry and wild boar population. The unfolding story of this swine fever outbreak investigation will be closely watched by agricultural and biosecurity experts across Europe.
