Phytosanitary inspection of woody plants for planting at european union entry points: A practical enquiry

Phytosanitary import inspections are important to avoid entry of harmful pests on live plants. In the European Union (EU), all consignments of live plants must be inspected at the first point of entry, and plants allowed entry can be moved without further inspection among the 28 Member States and Switzerland. It is important that inspections in EU countries adhere to the same standard to avoid introduction of harmful organisms through countries with weaker methods. We tested whether sampling intensity and confidence in the inspection results were the same across these countries. Questionnaires were sent to inspectors in all countries, asking about inspections of individual consignments of woody plants for planting. Data about 102 lots, inspected at 13 points of entry in six countries, were analyzed. We used hypergeometric and binomial statistics for small and large consignments, respectively, to calculate the probability that
