Table 2: Descriptive statistics (mean, median, standard deviation, minimum and maximum) for the frequency of animal and human–animal events annotated at unloading (T1) the frequency of animal and human–animal events annotated from the iairage pen door to the entrance of the stunning area (T2), and for the prevalence of carcass skin lesions. Table 2 also shows the descriptive statistics of the prevalence of carcass scored with the DMRI scale for skin lesion severity. On average, severe lesions (classes 3 and 4) for the rear and shoulder regions were observed in about 6% of the carcass in the 72; a higher prevalence was observed for trunk lesions, with severe lesions in the middle region exceeding on average 11% of the carcass in each batch. Out of the 72 batches, 41 had at least one carcass with severe lesions in the rear region, 17 of which had a prevalence of carcass with severe rear lesions above 10%.
