Although many animal diseases have been eradicated from the European Union (EU), the animal production sectors in the EU are still under a major threat of disease pathogens introduced by travellers into a country through illegal importation of wildlife or production animals, and/or food products of animal origin. These may carry (exotic) pathogens or toxic metabolites that are hazardous for public health and have a zoonotic potential. According to experts, newly emerging diseases will most probably be zoonotic in nature. The control systems and inspection measures at the borders are, in general, sufficient to control the import of disease pathogens through commercial consignments, as regularly reported by the Food and Veterinary Office (FVO). The Schengen Agreement in the EU has pushed such inspections to the outer borders of the EU in the context of freedom of movement of 'goods' - including live animals and foods of animal origin - people and services within the EU (Treaty of Rome). However, it is questionable whether this policy and the inspection measures taken are effective in reducing public and animal health risks in the EU to an acceptable level. Risk assessment studies point to the potential dangers of illegal imports by travellers. This review article discusses the current status quo and more, in particular, the weaknesses of the current inspection procedures related to biosecurity and suggestions for improvement are made.
