Xylella fastidiosa, a deadly bacterium for numerous plants, was first detected in Europe in 2013 and has spread to various regions, causing significant economic and environmental damage. The bacterium, transmitted by insect vectors, has been particularly impactful in Californian vineyards and Italian olive groves. In France, infection has been reported across three regions, with a containment strategy adopted in Corsica due to widespread environmental contamination, and eradication efforts underway in Provence-Alpes-Côte d'Azur and Occitanie. The European Union has implemented regulations to limit the bacterium's spread through measures such as plant removal, increased surveillance, and controls on plant movements. Public education and awareness are crucial to preventing the spread of the disease, including restrictions on the transport of plants from affected areas. Since 2015, France has conducted numerous inspections and analyzes to monitor the situation.
