Repair medium for the resuscitation of injured cells

A composition comprising:

• from about 2.5 to about 20% by weight of a non-selective complete nutrient medium;
• from about 0.10 to about 5.0% by weight of a yeast derivative selected from the group consisting of yeast extract, live yeast cell derivative and autolyzed yeast;
• from about 0.10 to about 5% by weight of one or more antioxidants;
• from about 0.0025 to about 5% by weight of an oxygen tension reducing agent;
• and
• from about 0.025 and about 5% by weight of chicken fat.

AN anaerobic repair medium for the resuscitation of injured, damaged or stressed Salmonella, E. coli, Staphylococcus aureus and Listeria monocytogenes food pathogens, which medium comprises:

• a non-selective complete nutrient medium in an amount effective to supply all nutrients required by said food pathogens;
• a yeast derivative in an amount effective to promote the repair of said food pathogens;
• one or more antioxidants in an amount effective to promote the repair of said food pathogens;
• an oxygen tension reducing agent in an amount effective to reduce the oxygen tension of said nutrient medium to anaerobic levels;
• and `one or more fatty acids required for membrane repair of said food pathogens between about 10 and about 25 carbon atoms in length and having from 0 up to 4 double bonds.
