Hi Richard,
Thank you for your reply. Yes, I did see this site but the D values are
too wide, for example 21-137 minutes at 90 C.
I also found the attached reference, but it also shows a very wide range
-- D85 at 33.8 - 106 min.
By the way, the attached also shows that it can grow at anaerobic
conditions.
Any info on z value?
Best regards,
Ted

Hi Ted
Have you tried this for D values:
http://seafood.ucdavis.edu/haccp/compendium/Chapt10.htm#Growth
Perhaps USFDA chose C. bot as it is more common in a marine context than
B. cereus. Also of course it is aerobic which will have a bearing on
its development in can.

Dear List,
I am reviewing HACCP for pasteurized canned crab.
Could somebody tell me why USFDA picked up C. botulinum tye E and
nonprot. B and F as the target microorganism for pasteurization instead
of Bacillus cereus which seems to be more heat resistant ? (FDA Hazards
and Control Guidance, Chap. 17: Pathogen Survival Through
Pasteurization).
Does anybody have information on B. cereus : D value, z value, etc?
Thank you very much.
