To our knowledge no data have yet been reported on non-
O157:H7 VTEC survival in DFS. Here, the importance of recipe and process variables on VTEC (O157:H7 and
O103:H25) reductions in two types of DFS, morr and salami, was determined through three statistically
designed experiments. Linear regression and ANOVA analyses showed that no single variable had a dominant
effect on VTEC reductions.
