    • His equipment is stored within the premises where the positive birds are.
    • The business has been operating in the Las Palmas farm (outbreak 1) since the beginning of the event, and then operated within the area of El Melón (outbreak 2).
    • This business represents a strong epidemiological link between both primary outbreaks.
    • Following the new detection, the affected premises were put under quarantine and additional samples were taken from birds.
    • Furthermore, the Farming and Agricultural Service (SAG) decided to pre-emptively destroy the whole bird population in this farm and adjacent farms.
