The United States Department of Agriculture-Food Safety and Inspection Services (UDSA-FSIS) has implemented a 7 log10 relative reduction in viable counts of Salmonella for fully and partially cooked poultry products (USDA-FSIS, 1999). Results from thermal inactivation experiments are often expressed as the D-value, the time needed at a particular temperature to inactivate 90% of the exposed bacteria (Table 2). Juneja et al. (2001) compared the inactivation of Salmonella in ground turkey and ground chicken and determined that the D-values for ground turkey were higher (0.59 min) than for ground chicken (0.50 min) at the highest temperature examined (65 C). Murphy, Duncan, Beard, and Driscoll (2003) also concluded that D-values varied by animal species at lower temperatures, although at the highest temperature studied (70 C) no statistical differences were seen among the Dvalues for duck breast meat, chicken breast meat or turkey breast meat (0.11, 0.10 and 0.12 min respectively). These authors concluded that there can be considerable differences in the time required for inactivation of Salmonella between avian species as well as with different fat levels within the same bird species at lower processing temperatures, but at temperatures as high as 70 C these differences become insignificant.
