European wild boar expansion causes agricultural and sanitary risks in Argentina
The European wild boar (Sus scrofa) is undergoing a massive population expansion across Argentina, particularly in the Buenos Aires province. Originally introduced in the early 20th century for hunting purposes, the species has escaped controlled environments and established itself in the Pampas region, including areas near Bahía Blanca, Villarino, and Patagones.
This biological invasion poses significant economic, environmental, and sanitary risks. Experts estimate direct agricultural damages—including crop loss, destruction of infrastructure, and soil disturbance caused by rooting—could range between US$ 1.3 billion and US$ 1.6 billion annually. The species' high reproductive rate and lack of natural predators have facilitated its spread, with some scientific estimates suggesting a population of approximately 4 million individuals.
Beyond agricultural impacts, the boars present public health concerns. A notable outbreak of trichinosis in Villarino, which affected over 50 people after they consumed wild boar meat, highlights the sanitary risks associated with the species. Additionally, the animals' movement near peri-urban areas and rural roads increases the risk of traffic accidents and environmental degradation.
