Technical Abstract: Salmonella associated human illnesses, linked to consumption of contaminated poultry, have remained significantly above public health targets of the Centers for Disease Control (CDC) whereas E. coli O157:H7, Campylobacter, and Listeria associated morbidities are approaching Healthy People 2010 goals. In reviewing NADC research targeting Salmonella and Campylobacter in turkeys, we emphasized that transport stress does not impact the levels of Salmonella in turkeys as described previously for swine. In contrast, population shifts in Campylobacter jejuni and most noticeably C. coli coincided with preslaughter events, including transport. Fundamental knowledge on the development of the microbiota in the turkey ceca from day of hatch to 18 weeks at which time birds are slaughtered is critical in understanding the impact of on-farm interventions, including administration of pre- and pro biotics. Basic knowledge on the cecal microbiota was emphasized as a research need by the Iowa Turkey Federation. Gene expression studies conducted in hogs may serve as a model for similar studies in turkeys challenged with Salmonella.
