Changes in the spoilage-related microbiota of beef during refrigerated storage under different packaging conditions

Article Abstract:

The microbial diversity of the spoilage-related microbial groups that develop during refrigerated storage of beef at the species level under different modified-atmosphere packaging (MAP) conditions is assessed by considering quality indices of significant importance for the acceptability of fresh meat by the consumer. The identification of the spoilage-related microbiota by molecular methods could help in effectively establishing storage conditions for fresh meat.

Modeling and predicting the simultaneous growth of Escherichia coli 0157:H7 and ground beef background microflora for various enrichment protocols

Article Abstract:

A study was conducted on the description of simultaneous growth of Escherichia coli 0157:H7 (0157) and the ground beef background microflora (BM), in order to characterize the effects of enrichment factors on the growth of these organisms. It was observed that the impact of the enrichment protocol factors was very little on the simultaneous growth of BM and 0157.

Direct molecular approach to monitoring bacterial colonization on vacuum-packaged beef

Article Abstract:

The application of culture-independent methods is described to study the microbial succession dynamics in vacuum-packaged beef stored at 2 and 8 degree Celsius for 9 weeks and 14 days respectively. These methods provided the information required about microbial diversity by identifying the main microorganisms capable of colonizing this ecological niche.
