The present study evaluated the incidence of B.
cereus in samples from 85 refrigerated dairy products through inoculation in selective medium and confirming according to biochemical proofs. Confirmed strains were then inoculated in specific growth medium at 7, 10 and 30°C to test the psychrotrophic behavior, and lipolytic and proteolytic activity.
B.
cereus was found in 15 of the 85 samples (17.6%); and 12 of them (80%) were let to grow up at 10°C for 7 days.
When incubated at 7°C for 10 days, four strains (26.7%) grew up.
All isolated B.
cereus strains have shown proteolytic activity at 30°C, and 5 (33%) also presented lipolytic activity.
