The microbiological quality of various sandwiches and meats packaged under modified atmosphere was evaluated. Samples were analyzed both on the day of manufacture and at the end of shelf life. On day 0, around 60% of products examined contained less than or equal to 10(5) total aerobic counts g-1, while at the end of the shelf life approximately 63.3% of samples contained greater than or equal to 10(7) cfu g-1. Listeria spp. were found in eight of the 58 lots examined, with L. monocytogenes being present in five of the eight samples. One lot was found to contain Aeromonas hydrophila, while another one contained Staphylococcus aureus. Clostridium botulinum and Salmonella spp. were not found in any of the samples.
