# Wild boar zoonotic and economic risks > Live situation record from CLSTR: https://clstr.news/situations/wild-boar-zoonotic-and-economic-risks > Updated: 2026-08-26T09:31:42.000Z. Sources: 10. Developments: 3. Wild boar populations in Argentina and Spain have been identified as significant carriers of zoonotic pathogens. In Argentina’s La Pampa province, a boar was confirmed to carry Trichinella sp., the parasite responsible for trichinosis. Similarly, a study in Málaga, Spain, found that over 90% of urban wild boars carried infectious pathogens, including hepatitis E, Salmonella enterica, and Escherichia coli O157, prompting calls for increased biosecurity and surveillance. In Argentina, the situation has escalated due to the massive population expansion of the European wild boar (Sus scrofa), particularly in the Buenos Aires province. Originally introduced in the early 20th century for hunting, the species has escaped controlled environments and established itself in the Pampas region, including areas near Bahía Blanca, Villarino, and Patagones. This biological invasion, with an estimated population of 4 million individuals, poses severe economic and sanitary threats. Experts estimate annual agricultural damages—including crop loss, infrastructure destruction, and soil disturbance—between US$ 1.3 billion and US$ 1.6 billion. Furthermore, a trichinosis outbreak in Villarino involving over 50 people underscores the public health risks associated with consuming wild boar meat. In Spain, research in the Málaga province regarding wild boars and feral pigs in municipalities such as Marbella, Fuengirola, and Benahavís found that approximately 86% of subjects carried agents with zoonotic potential. Dr. Esther Hurtado, Head of Emergency Services at Hospital Quirónsalud Marbella, noted that while these findings require monitoring due to human-wildlife interaction, they do not constitute a “sanitary alarm situation,” as pathogen presence does not guarantee human transmission. ## Claims - European wild boars (Sus scrofa) were introduced to Argentina for hunting purposes. (corroborated by 3 sources) - The species was brought from Europe by Pedro Luro to his San Huberto estate in La Pampa at the beginning of the 20th century. (corroborated by 3 sources) - Adult males weigh between 80 and 140 kilograms. (corroborated by 3 sources) - Females have a gestation period of approximately 115 days and can give birth to 4 to 8 offspring. (corroborated by 3 sources) - The expansion of the species causes damage to crops, soil, and biodiversity. (corroborated by 3 sources) - The species poses environmental, productive, and sanitary risks. (corroborated by 3 sources) - The presence of pathogens in wild boars does not constitute a sanitary alarm situation. (corroborated by 3 sources) - A study of 80 wild boars and feral pigs in Málaga revealed over 90% had been exposed to a pathogen. (corroborated by 3 sources) - Approximately 86% of the analyzed animals presented agents with zoonotic potential. (corroborated by 3 sources) - People should seek emergency medical care for any bites or wounds from wild boars. (corroborated by 3 sources) - Prevention involves avoiding contact with wild boars and not feeding them. (corroborated by 3 sources) - The presence of European wild boars is documented near Bahía Blanca, Villarino, Patagones, and mountainous areas.
