The United States has seen 70 Salmonella outbreaks linked to contact with live poultry between 2000-2017, resulting in 4794 cases, according to reports from the US Centers for Disease Control and Prevention (CDC). The most recent surveillance reports indicate that live poultry-related outbreaks are on the rise with 9 outbreaks reported in 2016 and 10 reported in 2017.
Despite the frequency of live poultry-related outbreaks, environmental sampling is not routinely conducted during outbreak investigations. As a result, the source of the outbreak is rarely identified.
However, on June 12, 2018, the Michigan Department of Health and Human Services (MHHS) requested assistance from the CDC to investigate Salmonellarisk factors at a mail-order hatchery. The findings of the investigation were published in the CDC’s Morbidity and Mortality Weekly Report.
