Comparative ad hoc analysis of phytosanitary efficiency in EU

The number of harmful plant pests and diseases intercepted in phytosanitary checks of plant materials during import and intra-community movement by EU member states in 19992008 were compared with import volumes, and the ad hoc phytosanitary efficiency indices were calculated. There were but minor significant differences in phytosanitary efficiency between the member states which had joined before 2004 and the new member states. Several factors, like raw material import volumes, geographic position and the island effect were found to explain differences in phytosanitary efficiency among the member states.
