Technicians in Portugal have confirmed the presence of Xylella fastidiosa bacteria in a batch of rosemary plants from a nursery in Luz de Tavira and Santo Estevão, and in a flower bed in Massamá and Monte Abraão, Sintra. The European Union-mandated phytosanitary measures have been implemented, including the establishment of Demarcated Zones, and extensive sampling of other susceptible plants and the investigation of vector insects is underway. The first confirmation of Xylella fastidiosa in Portugal was in 2018, and the bacterium can spread over long distances and affect a variety of plants.
