Disinfectants that are usually applied against bacterial spores in
food industry must be tested for their sporicidal efficacy. In addition
those tests should include test organisms (spores) with a
representative susceptibility. In this study spore suspensions of
B. cereus, one of the most resistant spore former and foodborne
pathogen, have been used. Different toxicogenic types (DSM 4212,
4313, 4384) were compared with each other and with a strain from
environment (DSM 318). B. cereus strain DSM 4313 (diarrheal type)
was the most resistant spore-former and pathogen in this study.
Correlations between toxicogenic types and a higher resistance
could not be demonstrated
