*Yersinia enterocolitica* was first identified as a human pathogen in the mid-20th century, distinguishing it from the plague-causing *Yersinia pestis*. Its recognition helped clarify the cause of various gastrointestinal and systemic infections previously undiagnosed, increasing understanding of foodborne illnesses.
Yersiniosis primarily spreads through the fecal-oral route, often by consuming raw or undercooked pork, contaminated unpasteurized milk, or untreated water. Direct contact with infected animals, especially pigs, or their feces can also lead to transmission, as can person-to-person spread in household settings or childcare centers.
