Challenge tests are commonly employed to evaluate the growth behavior of L. monocytogenes in food matrices;
they are known for being expensive and time-consuming. An alternative could be the use of predictive models to
forecast microbial behavior under different conditions. In this study, the growth behavior of L. monocytogenes in
different fresh produce was evaluated using a predictive model based on the Gamma concept considering pH,
water activity (aw), and temperature as input factors. An extensive literature search resulted in a total of 105
research articles selected to collect growth/no growth behavior data of L. monocytogenes. Up to 808
L. monocytogenes behavior values and physicochemical characteristics were extracted for different fruits and
vegetables. The predictive performance of the model as a tool for identifying the produce commodities supporting
the growth of L. monocytogenes was proved by comparing with the experimental data collected from the
literature. The model provided satisfactory predictions on the behavior of L. monocytogenes in vegetables (>80%
agreement with experimental observations). For leafy greens, a 90% agreement was achieved. In contrast, the
performance of the Gamma model was less satisfactory for fruits, as it tends to overestimate the potential of acid
commodities to inhibit the growth of L. monocytogenes.
