3.2. Experiment 2: cooling characteristics and microbial evaluation
The hot carcasses showed a mean weight of 288.64 ± 22.48 kg, and 55% were classified as having absent fat cover, 43% as scarce fat cover and 2% as average fat cover. None of the carcasses showed a rupture of
the gastrointestinal tract during the slaughter process, and there was no contamination of fecal origin on the carcass surface during inspection at the critical point of biological control (HACCP system), which is conducted
by the production company. The mean temperature and airflow rate of the chamber for the 24 h of chilling were 3.61 ± 1.55 °C and 1.38 ± 0.23 m/s, respectively.
