• This Quick scan was prompted by the first finding of the bacterium Pseudomonas kitaguniesis in the Netherlands. This bacterium was not known to be present in the EU. 

• Pseudomonas kitaguniesis is a recently described species and was previously only known from Japan and New Zealand. The origin of the infestation in the Netherland is unknown. 

• Pseudomonas kitaguniesis was already known as a pathogen of Welsh onion (Allium fistulosum) and is probably also a pathogen of leek (Allium ampeloprasum var. porrum). Damage may especially occur during cool and wet conditions. However, the impact (% yield loss) that can be expected is highly uncertain. Leek plants appeared to recover when the weather became warmer and drier.
