Resuscitate debilitated cells by incubating 1:10 dilutions of the food samples under investigation in Tryptone Soya Broth CM0129 at 25°C for 2-8 hours. The fluid layer should not be much deeper than one centimetre. Shake the flask to disperse the contents alternately in clockwise and anti-clockwise directions for 30 seconds on three successive occasions.2. After the period of time necessary for resuscitation, ten-fold volumes of EE Broth are added to the resuscitated suspensions.3. Shake to disperse as above. For large samples it is desirable to add the resuscitation medium containing the product under examination, to equal volumes of double strength EE Broth.4. Incubate at 44°C for 18 hours for thermotrophic bacteria; 32°C for 24/48 hours for mesophilic bacteria; 4°C for 10 days for psychrotrophic bacteria depending on the groups of Enterobacteriaceae sought.5. Examine the tubes of broth and look for turbidity with some change of colour towards yellowish-green for presumptive evidence of Enterobacteriaceae.6.
