ABSTRACT This study aimed to evaluate visual contamination rates of carcasses of broilers slaughtered in establishments supervised by the Federal Inspection Service (SIF) and efficiency of carcass washing in replacement of trimming. The work was divided into three parts: analysis of partial and total carcass condemnation by contamination in hot (October to March) and cold (April to September) periods; evaluation of microbiological contamination before and after washing 800 carcasses (400 that did not go through washing x 400 that went through washing); and carcass washing test. For the test, twenty carcasses were evaluated in five treatments: carcasses without contamination - before washing; carcasses without contamination - after washing; contaminated carcasses - before washing and before trimming; contaminated carcasses - after washing; contaminated carcasses - after trimming. Hot and cold periods obtained a similar number and weight of slaughtered chickens. There were no differences regarding condemnation by contamination. Periods of the year did not influence the average weight of the birds slaughtered in the state of Mato Grosso do Sul. Carcass washing in the slaughter line was effective in reducing total bacterial contamination, E. coli, and enterobacteria. There is a similarity in the reduction of condemnations by contamination, evidencing that the uniformity of production systems. Although it is not yet a reality in Brazilian slaughterhouses, the washing procedure can be considered a safe replacement for trimming.
