English: Dick Culbert: Opuntia species often host a parasitic scale insect (Dactylopius coccus), which hides below a white scum. When smeared, these bugs yield a carmine dye called Cochineal. This is a product in great demand as coloring for lipsticks, meat and other foods. Using this, one can claim "no artificial dyes". Customers are ignorant of the 'Yuk Factor'.
