    Anne,

    If you can prove that by controlling belt speed and steam tunnel temperature
    that each and every product exiting the cooker will have reached the
    appropriate internal temperature, then you could, IMHO, use belt speed and
    tunnel temperature as your critical limits for the cook step CCP.

    Now, the question is, how can you prove it? You need to conduct a study
    demonstrating how belt speed and tunnel temp are correlated with end product
    temperature for each size product you are processing. Once this correlation
    is known you can set belt speeds and tunnel temps. that are appropriate for
    the product. Remember that each size product will require different
    time/temp combinations. Initial product temp also would be a variable. You
    can verify/validate the adequacy of the CCP by periodic monitoring of end
    product temperature. Obviously continuous monitoring is best, but under
    your circumstance you can continually monitor belt speed and tunnel temp.
    Be sure to keep excellent records of the study and of subsequent monitoring.

    Something that may help you with your inspector is to have an independent
    process authority validate your operation.

    FWIW,

    Doug

    Listservers,Thanks for the input last week.I realized
    that I didn't word one of my questions well so maybe
    I can reword it to make sense. I am very aware that
    one CCP for shrimp would be the cook step, we had
    used the belt speed and the time as our verification.We
    were given the Okay to use the Crab process study that
    the NFPA had done and use the core temp. as an
    alternative to the time and temp. criteria. which we have done since 1999.
    An FDA inspector has now told us
    that this is not "Continuous" which is the word used in the guide.I don't
    disagree but the guide suggests a temp. recording device and I am not all
    that familiar with something that can be attached to the peelers.
    I have a chart recorder to monitor our cooler,I understand the whats and
    hows of its use pertaining to our cooler
    temperature,but we need to put them on the shrimp peelers? I don't
    understand that concept because the only
    temp. it would be recording is the steam temperature, and
    not a core temperature as we do now ,can someone
    tell me what other processors use for the shrimp cook step verification
    that would make the regulatory agencies
    happy .This has been haunting me for months ..I'll be
    grateful... Thanks again.
