Knowledge gaps exist regarding foodborne zoonotic diseases in migrant populations. We assessed the seroprevalence of Campylobacter, Salmonella, Yersinia, Brucella, hepatitis E virus (HEV), and Trichinella, and identified potential exposure risks in populations with and without migration backgrounds. In a cross-sectional study (2014–2016), adults with Turkish, Russian, Vietnamese, or German backgrounds residing in Berlin, Germany, were recruited via convenience sampling. Sera were screened for anti-IgG antibodies, and risk factors were assessed via a structured questionnaire. Logistic regression was used for analysis. We included 1180 participants: 497 Germans and 215, 273, and 195 individuals with Russian, Turkish, and Vietnamese backgrounds, respectively. Salmonella seroprevalence was highest among Vietnamese (47–50%) and lowest among Turks (18–20%). Campylobacter seroprevalence ranged from 17% to 23%. Yersinia seroprevalence was highest among Germans (64–70%) and associated with raw pork consumption. HEV seropositivity was highest among Vietnamese (27–28%) and lowest among Russians (5%). No samples were positive for Brucella; two were positive for Trichinella. High seroprevalence of Campylobacter, Salmonella, Yersinia, and HEV suggests substantial exposure and frequent asymptomatic or mild infections. While Yersinia seropositivity was associated with raw pork consumption, high seroprevalence in Turks—who rarely consume pork—suggests other food sources or transmission routes.
