| This study evaluated the growth of naturally occurring L. monocytogenes in sliced, vacuum-packed mortadella samples during storage at 5ºC until the expiration date. Tukey's test indicated that counts of L. monocytogenes on 0, 10, 20, 30 and 40 days of storage were significantly different (p<0.05), indicating growth during shelf life. In three trials, the mean increase was 1.72 log cycles. Vacuum packing and storage under refrigeration were not effective in controlling the growth of L. monocytogenes in sliced mortadella, indicating that good manufacturing practices and implemented HACCP programs are essential to assure safety of this product. |

| Enumeration of aerobic microorganisms in Brazilian pasteurized bovine milk using PetrifilmTM AC and SimplateTM 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 PetrifilmTM AC and SimplateTM 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 PetrifilmTM AC counts were "good", but "poor" using SimplateTM TPC. Comparison of... |
