    Carbon monoxide by any other name is still carbon monoxide. Since
    complexation with myoglobin and hemoglobin obscures natural color changes
    in meats associated with spoilage and it is a toxicant (which is improperly
    labeled if at all) its use constitutes adulteration under US law and I am
    sure under anyone else's laws. This reminds me of other ingredient scams
    wherein a material was ostensibly added for one purpose but its true
    purpose, recognized by everyone, was something else, usually illegal.

    Why are our regulatory authorities winking at this practice? They risk
    losing all credibility in the eyes of both consumers and scientists if they
    continue.

    And is it really true that one cannot detect application of CO to meats
    when the 'tasteless smoke' process is used? I seem to recall that the
    complexed pigment has a clearly different wavelength of maximum absorption.
