I agree with Caz, My favorite phrase, "That information is proprietary."
Imagine what that would do to companies and overall consumer behavior if all customer complaints were to become public. How would we know the numbers are honest? How would false claims be handled (reported or not?) Who justifies if it was a false claim in order not to report?
I won't buy from there! They had a complaint of a person that found a Band-Aid in their food! [Even though it was skin tone color rather than a metal detectable blue Band-Aid which is all that is used in the plant] <~~~~would this be placed on the foot notes? Most media will just read on the Headline (Which is the only part most people read) CUSTOMER FINDS BLOOD IN FOOD and somewhere in some obscure small font writing at the end of the article. It was actually some strawberry flavor topping.
Like most people in this thread suggest, make your own charting log and trend. Most GFSI schemes require this and also require some sort of quantifiable way to show you're continuously improving in some food safety facet which can be easily done with trending last years complaints versus this years.
