>>>On the very rare occasions that I feed my bees, I normally add blue food dye to show where it ends up. Maybe the same could be done with Purina. <><><> I, too, used food coloring to tag the syrup supplement that I give to my bees. I do this in an effort to ensure that I am not contaminating my honey product with sugar syrup. A side note to this is that one late spring, when going through my hives, I found one of my stronger hives had numerous frames of color tinted honey. They had been robbing one/some of my weaker colonies which I had been feeding. Anyway, any time that I find colored cells of honey, food coloring tinted, I refrain from extracting that frame of honey.
