If we start with the fact that there is no perfect operation, you could find something wrong in almost any picture, and it is common that even in pictures used for brochures, training and presentation you could find at least a little improvement opportunity.
Now, with that said; what is wrong in here is obvious to me; when the picture was taken, they were more concerned about the esthetic of the picture than food safety itself. I’ll dare to say they just hired a photographer and asked him to take pictures for a brochure; marketing worked on this and was not reviewed from a food safety stand point.
The excessive makeup and the nice sweeter is proof of that, but also the fact that the fruit bowls are placed on baking trays to display. (By the way, I don’t think is rust or dirt, those are used baking trays with baking residues).
Now, after many copies had being printed and distributed, it was probably easier to find reason (or excuse) to get along with the makeup. Although makeup may not be explicit in Codex, and it may not ba a major concern for pathogenic contamination, it may represent chemical contamination..., if not, how many of you would like to buy one of those biscuits with lipstick on it?
