A Q fever outbreak among an unvaccinated goat herd led to a 65% loss of the kid crop in spring 2018. To assess the impact of the outbreak on the herd and environment, longitudinal surveillance of the ranch was conducted across three samplings in September 2018, April 2019, and May 2022. Antibodies against\n                    <jats:italic>C. burnetii<\/jats:italic>\n                    were monitored by an indirect immunofluorescence assay. Shedding was monitored through analysis of vaginal\/fecal swabs and milk. Environmental swabs and bulk soil were collected from various locations around the ranch. Animal and environmental samples were analyzed for\n                    <jats:italic>C. burnetii<\/jats:italic>\n                    DNA by PCR. Herd-level seroprevalence decreased from 89% in 2018 to 84.3% in 2019, and 64.5% in 2022. Overall herd shedding was 14.4% in 2018, 7.4% in 2019, and 6.7% in 2022. The percentage of\n                    <jats:italic>C. burnetii-positive<\/jats:italic>\n                    environmental samples was 83.7% in 2018, 51.7% in 2019, and 28.6% in 2022. Serological evidence suggests that new infections were occurring in the herd 4\u2009years post-abortion storm. This study demonstrates the presence of\n                    <jats:italic>C. burnetii<\/jats:italic>\n                    shedding and environmental contamination in a goat operation at least four kidding seasons after an outbreak.
