Backyard and exhibition poultry have been gaining in popularity and as such there has been a large increase in the number of small flocks. As the interaction with poultry has increased, so has the opportunity for diseases and parasites, for both birds and people. One of the major zoonotic illnesses is caused by the bacteria Salmonella, which can be found in commercial and small flocks. Salmonella is the number 2 contributor of foodborne illnesses so its prevalence in commercial flocks is of high concern. Despite improved cleaning, disinfection, and biosecurity practices, there is still potential for disease outbreaks and infections in the industry. This thesis concentrates on helping small flock holders fight diseases. In a two pronged approach I looked at preventing Salmonellosis by evaluating the efficacy of 6 disinfectants, then took the opportunity to sample and evaluate the prevalence of internal parasites in small flocks in Arkansas. Results found that household bleach is an effective disinfectant, whereas lemon juice and vinegar are not as effective as commercial disinfectants. Additionally, internal parasites are common in backyard flocks in Arkansas.
