SUMMARY:

This study evaluated the efficiency of the liquid manure stabilization process in storage units in 10 pig farms located in the municipality of Presidente Castello Branco (SC), Brazil. The work was carried out in two trials: in the first, the efficiency in reducing Escherichia coli and Salmonella sp. under ideal management conditions (Hydraulic Retention Time = 60 days), as well as the resistance of the isolates to antimicrobials. Sampling was carried out in manure pits at three levels of depth, at times T0 and T60. In trial 2, the concentration of total and fecal coliforms (EC) was investigated under real management conditions. Regarding the indicator bacteria, the depth of collection did not affect the concentration, but the TRH was significant in reducing the levels of these populations. Bacterial multiresistance to antibiotics was observed. In the field, the concentration of EC under ideal management conditions was lower when compared to operational conditions. The handling of swine manure when carried out in disagreement with sanitary norms may imply risks of propagation of pathogenic microorganisms, in the same way that the resistance of bacteria to antibiotics harms the homeostasis of one health.
