Evaluation of standardized operating and sanitation procedures in the pig slaughtering process

The purpose of this research work was to evaluate the Standardized Operational and Sanitation Procedures in the pig slaughtering area of ​​the MFL ESPAM Meat Shop, a diagnosis was made through a checklist to identify the sources of microbial contamination, being the most significant slaughtering operations; Microbiological analyzes of aerobic mesophiles, Salmonella, E. coli, and Staphylococcus aureus were performed, applied to pigs managing to detect the lack of microbiological safety. Subsequently, personnel who slaughter pigs were trained and the process line was improved to correct bad hygiene practices. A significant improvement was demonstrated through the checklist in the BPM compliance percentages, which had an 18% compliance before the implementation of the SOPs and SOPs compared with 43% after its execution. The microbiological results of the before and after the implementation of POE and POES were analyzed by binary logistic regression, and through the bus test it was shown that all the models planned for each pathogenic microorganism were significant (p <0.05), in addition to the regression It allowed to show that the implementation of POE and POES favors microbiological safety, with the probability of absence of 62.5% for Staphylococcus aureus, 79.2% for mesophilic aerobes and 50% for E. coli.
