    Hi Peter and Seafood HACCP Discussion List Subscribers,

    The FDA HACCP reference that Andrew is referring to is the "Fish and
    Fisheries Products Hazards and Controls Guidance Chapter 16: Pathogen
    Survival through Cooking". It is on the web at:
    http://www.cfsan.fda.gov/~comm/haccp4p.html and says the following:

    "Selection of the target pathogen is critical. Generally, Listeria
    monocytogenes is selected, because it is regarded as the most heat
    tolerant, food-borne pathogen that does not form spores. Cooking processes
    are not usually designed to eliminate spores of pathogens. Determining the
    degree of destruction of the target pathogen is also critical. Generally,
    a reduction of six orders of magnitude (six logarithms) in the level of
    contamination is suitable."

    Appendix 4, "Bacterial Pathogen Growth and Inactivation" of the FDA's
    Guidance provides additional information.
    http://www.cfsan.fda.gov/~comm/haccp4x4.html

    The Hazards Guidance table of contents is at:
    http://www.cfsan.fda.gov/~comm/haccp4.html

    Please note, the FDA is updating the Guidance. News about the new
    edition is expected to be announced later on this year.
