Enumeration of aerobic microorganisms in Brazilian pasteurized bovine milk using Petrifilm TM AC and Simplate TM TPC was shown to be influenced by the nature of autochthonous microbiota. This study was conducted to assess if the same occurs in pasteurized goat milk. Pasteurized frozen goat milk (n=62) was purchased in retail stores in São Paulo, SP, Brazil, and submitted to mesophilic aerobic counts using Petrifilm TM AC and Simplate TM TPC, comparing results with those of conventional pour-plates. Correlation indexes above 0.90 were ranked "excellent"; those between 0.80 and 0.89, "good", those from 0.79 to 0.50, "fair", and those below 0.50, "poor". Correlation indexes for Petrifilm TM AC counts were "good", but "poor" using Simplate TM TPC. Comparison of Petrifilm TM AC and Simplate TM TPC also produced "poor" correlation indexes. Results suggest that autochthonous microbiota have little, if any, influence on the performance of these two systems, since good correlations were achieved using Petrifilm TM AC.
