Predicted log10 increase and log10 difference of Listeria monocytogenes and Aeromonas hydrophila on fresh fishery products when transported/stored in tubs or boxes based on the observed time/Temperature profile in experiment 1 of the ‘Qualitubfish’ project (Bekaert et al., 2016a)

A positive value indicates a greater growth potential (log10 increase) in tubs compared to boxes, while the opposite is true for the negative values. The range represents the minimum and maximum difference considering any combination between the log10 increase in tubs and boxes.
