National officials investigating the ongoing African swine fever outbreak in the northeastern region are now considering the possibility that the disease could have originated from a research facility. Their focus has narrowed to five nearby labs as potential sources.

Outbreak Details and Industry Concerns

A total of thirteen cases of the virus have been identified in feral pigs in the countryside outside the Catalan capital beginning on 28 November. This has prompted Spain – the European Union's biggest pork exporter – to rush to contain the situation before it escalates into a serious threat to the nation's €8.8bn-a-year pork export industry.

Shifting Theories of Origin

Initially, local authorities believed the disease may have begun after a boar consumed contaminated meat products imported from abroad – perhaps a thrown away meat sandwich from a haulier.

However, the Spanish ministry of agriculture has opened a new investigation after determining that the strain of the pathogen detected in the deceased animals in the region is different from the one reported to be present in other European countries. According to a report suggest the identified virus is rather akin to one detected in the country of Georgia in the year 2007.

"The discovery of a virus similar to the one that circulated in Georgia does not, therefore, rule out the possibility that its source lies in a biological containment laboratory," said the agriculture department.

Laboratory Link Examined

The 'Georgia 2007' viral strain is a 'standard' pathogen commonly used in experimental infections in containment facilities to study the disease or to test the efficacy of vaccines, which are presently being developed. The report implies that the virus may not have started in animals or animal products from any of the countries where the disease is currently present.

Official Response and Review

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

"We are not excluding any possibilities when it comes to the origin of the incident of this disease, but nor are we confirming any," the official stated. "Every theory remain on the table. First and foremost, we need to know what happened."

Latest Containment Measures

The authorities have confirmed thirteen infections of the virus – all of them in deceased feral pigs found within six kilometers of the initial focus. They have said the corpses of an additional 37 wild animals found in the zone have been analysed, with all showing no infection for the virus. Experts dispatched to the 39 swine operations within the surrounding zone have found no sign of the illness there. More than one hundred members from the country's emergency response forces have also been sent to the region to work alongside law enforcement and wildlife rangers.

Worldwide Background of ASF

For a long time native to the African continent, ASF is not dangerous to humans but often deadly to pigs. In 2018, the disease turned up in the People's Republic of China, which is home to about 50% of the world’s pig population. By the following year, there were fears that up to 100 million animals had been culled or died. Subsequently, the virus was detected to be in the Federal Republic of Germany, a country with one of the EU’s biggest swine herds.

The Country's Pivotal Role in Pork Production

The nation, which is the European Union's largest producer of pig meat, sold pig meat products worth 5.1 billion euros to other EU countries last year, and almost 3.7 billion euros of pig-based goods to destinations outside Europe. National data indicate that the country slaughtered 58 million pigs in 2021 – an increase of 40% from a ten years prior.
