African swine fever (ASF) has been discovered on the island nation of Cabo Verde for the first time since 2009, the World Organisation for Animal Health (OIE) reported.

A swine herd of mixed breeds had been experiencing high mortalities, with 450 pigs dying, and another 150 testing positive. According to the OIE, a total of 1,000 animals were susceptible. Tests were conducted by the Veterinary Laboratory of the General Directorate for Agriculture and Rural Development.

The source of the ASF outbreak in Cabo Verde has been listed as inconclusive, but OIE noted that the affected farm was near a landfill and that the animals on the farm had been fed with waste from hotels, restaurants and other sources. The affected pigs could have also had contact with sick swine on the island, OIE noted.

The animals have been quarantined. Other control measures implemented include movement control inside the country, screening, zoning, dipping and spraying. The affected property will be disinfected.

ASF has been a disease of growing concern for the global pig industry, as numerous cases have been reported. The most recent reports of ASF from the OIE have included outbreaks in Russia, Poland, Estonia, Latvia and Lithuania.

OIE stated it will submit weekly follow-up reports on the Cabo Verde ASF case.
