In the USA,<jats:italic>T. gondii<\/jats:italic>infects &gt;10% of the population, accrues economic losses of US$3.6 billion\/year, and ranks as the second leading culprit of foodborne illness-related fatalities. We assessed toxoplasmosis risk among the Old Order Amish, a mostly homogenous population with a high prevalence of<jats:italic>T. gondii<\/jats:italic>seropositivity, using a questionnaire focusing on food consumption\/preparation behaviours and environmental risk factors. Analyses were conducted using multiple logistic regression. Consuming raw meat, rare meat, or unpasteurised cow or goat milk products was associated with increased odds of seropositivity (unadjusted Odds Ratios: 2.192, 1.613, and 1.718 , respectively). In separate models by sex, consuming raw meat, or consuming unpasteurised cow or goat milk products, was associated with increased odds of seropositivity among women; washing hands after touching meat with decreased odds of seropositivity among women (adjusted OR (AOR): 0.462); and cleaning cat litterbox with increased odds of seropositivity among men (AOR: 5.241). This is the first study to assess associations between behavioural and environmental risk factors and<jats:italic>T. gondii<\/jats:italic>seropositivity in a US population with high seroprevalence for<jats:italic>T. gondii<\/jats:italic>. Our study emphasises the importance of proper food safety behaviours to avoid the risk of infection.<\/jats:p>","DOI":"10.1017\/s0950268820002897","type":"journal-article","created":{"date-parts":[[2020,11,25]],"date-time":"2020-11-25T06:54:58Z","timestamp":1606287298000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":7,"title":["Risk factors for<i>Toxoplasma gondii<\/i>seropositivity in the Old Order Amish"],"prefix":"10.1017","volume":"149","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7969-3123","authenticated-orcid":false,"given":"A.
