Summary

The observed times to 1-log increase in counts for 25 samples in which growth occurred were compared to times predicted by the US Dept. of Agriculture Pathogen Modelling Program. The latter model, based on storage temperature, and initial pH, nitrite and salt concentrations, explained only 12.4% of the variation in the observed times. The results suggest that retail wieners may support growth of L. monocytogenes, which could present a health hazard to target groups of consumers if subjected to post-processing contamination. They also suggest that further work is needed to derive adequate models to allow an accurate prediction of the growth of L. monocytogenes on ready-to-eat meat products.
