Spain investigates whether the outbreak of swine flu was caused by a lab leak

Catalonia's regional government announced on Friday that it would look into a research center outside Barcelona, after the Spanish Agriculture Ministry reported a recent

swine fever outbreak

A laboratory leak could have caused the problem.

Spain, Europe's largest pork producer, is trying reassure its trading partners following the positive test results of 13 wild boars in the hills surrounding the city. The virus is not harmful to humans, but it can be fatal for wild boars and pigs.

The ministry reported that a Madrid laboratory's genome sequencing revealed the strain to be "very similar" with one originally detected in Georgia in 2007. This strain is now widely used for research and vaccine development. The ministry said that other cases in Europe are from a different group of genetics.

The Agriculture Ministry stated that "the discovery of a similar virus to that which circulated in Georgia does not exclude the possibility that it may have its origin in a biological storage facility."

Catalan officials believed that the virus spread when a wild boar consumed contaminated food. It could have been a sandwich imported from abroad by a driver.

The ministry stated that "the report suggests that there is a possibility that the virus' origin is not animals or animal products in any of the current countries where it is present."

In its statement, it did not mention any labs. Oscar Ordeig said that the Catalan government will investigate the state-funded Centre for Research in Animal Health.

The centre is situated next to the Autonomous University of Barcelona, and it falls within the confinement zone of six kilometers (four miles) imposed by the authorities following the outbreak. Ordeig stated that other laboratories may also be investigated.

In 2017, the World Organization of Animal Health designated Cresa a research center into swine flu.

The laboratory did respond immediately to a comment request, but told news verification website Maldita.es that it found no evidence pointing towards it being the cause of the outbreak.

According to the Organisation for Economic Cooperation and Development, "Georgia 2007," swine flu spread to Armenia and Azerbaijan as well as Russia and Belarus and eastern EU states by 2014.

In 2018, it reached China, causing massive losses. In 2019, the Chinese pork meat production fell by 27%. Reporting by Charlie Devereux and Joan Faus; editing by Mark Potter, Heinrich and Mark Potter.
