- "Predicting Growth-No Growth of Listeria monocytogenes on Vacuum-Packaged Ready-to-Eat Meats"
Ingham SC, Borneman DL, Ane C, Ingham BH, Journal of Food Protection 73(4): 708-714 Apr 2010. Equations accurately predicted L. monocytes growth or no growth and with our equations for predicting S. aurens growth will be useful for evaluating RTE meat shelf stability.
- "Validation of Ground-and_Formed Beef Jerky Processes Using Commercial lactic Acid Bacteria Starter Cultures as Pathogen Surrogates"
Borowski AG, Ingham SC, Ingham BH. Journal of Food Protection 72 (6): 1234-1247 June 2009.Beef jerky has been linked to multiple outbreaks of salmonellosis and Escherichia coli O157:H7 infection over the past 40 years. With increasing government scrutiny of jerky-making process lethality, a simple method by which processors can easily validate the lethality of their ground-and-formed beef jerky process against Salmonella and E. coli 0157:H7 is greatly needed.
- "Factors Associated with Salmonella Prevalence on Pork Carcasses in Very Small Abattoirs in Wisconsin"
Algino RJ, Ingham BH, Ingham SC, et al., Journal of Food Protection 72 (4): 714-721 Apr 2009. The objectives were to survey the prevalence of Salmonella on pork carcasses in very small Wisconsin abattoirs, and identify processing conditions and indicator bacteria levels associated with reduced Salmonella prevalence.
- "Manual Squeezing as an Alternative to Mechanical Stomaching in Preparing Beef Carcass Sponge Samples for Microbiological Analysis"
Ingham SC, Algino RJ, Ingram BH, et al., Journal of Food Protection 72 (2): 428-430 Feb 2009. In this study, the USDA sample preparation procedure was compared with repeatedly squeezing the sponge during a 10-s interval to expel the sample fluid.
- "Use of Enterobacteriaceae Analysis Results for Predicting Absence of Salmonella Serovars on Beef Carcasses"
Ruby JR, Ingham SC, Journal of Food Protection 72 (2): 260-266 Feb 2009. In this study, the accuracy of a predictive approach was tested using varying data sets. The predictive approach used a large data set of carcass sponge samples from three large-volume beef abattoirs, and highlighted the potential use of binary (present or absent) Enterobacteriaceae results for predicting the absence of Salmonella on carcasses.
