If it feels like there are wild boars everywhere now, you're not imagining things. Now, besides causing damage to agricultural crops and invading suburban backyards, these wild boars could also be helping to spread antibiotic-resistant bacteria, according to a new study from Brazil. Public-health officials in Brazil have been concerned that the commercialization of wild boars, which are being bred for food there, may harbor zoonotic and antimicrobial-resistant bacteria. European wild boars weren't always part of South America's landscape. Domestic pigs arrived with European settlers centuries ago, while wild boars were introduced in the early 1900s by an Argentine rancher for hunting.
