The public health risks associated with wild and feral swine.

Abstract

Wild swine populations (Sus scrofa) are present in many regions of the world. Large feral populations in North America and Australia are principally derived from introduced domestic pigs. In Europe, most wild boar are found in Germany and Poland. While wild swine are certainly a significant reservoir of infection for domestic swine diseases (for example, African swine fever virus in wild boar in Sardinia), these swine generally do not constitute a major public health risk. Brucella suis infections and trichinellosis are the most important zoonotic threats to public health.
