-- Epidemiological comments

A 3-km-radius zone around the outbreak as well as a 10-km-radius surveillance zone beyond the previous one have been established.

In the zone around the outbreak, all pig farms were inspected and no animals with clinical signs were found. Only movements to the slaughterhouse are authorized after an official clinical inspection has been carried out.In the surveillance zone, pig farms are being visited in order to conduct clinical inspections and surveys with the owners. To date, no new health information has been reported. Movements of pigs to any destination are authorized after an official clinical inspection has been carried out.

Four farms with an epidemiological link were also identified; they were visited by the same veterinarian who had visited the affected farm during the past 30 days. These farms were inspected and no new health information was reported.

No more sick animals have been observed in the outbreak since 24 June. On 25 June, samples (nasal swabs) were taken in 50 pigs from different categories (all less than 150 days old); they were negative for the RT-PCR test.

Animals were sent to the slaughterhouse after the results of the clinical inspection and the RT-PCR were negative; no new health information was reported after the ante- and post-mortem inspection.
