We searched the literature to identify the zoonotic pathogens known to occur in animals of each taxon in the database. Only data on live animal importations (as opposed to animal products) and importations for which the genus was known were retained for analysis. Statistical analyses were performed by using Intercooled Stata 9 (StataCorp, College Station, TX, USA). In our fi nal risk assessment, we did not account for the origin of each specifi c importation because of limitations in the database, likely caused by a complicated system of exportation and reimportation.
