Ugh, there's Red #40 in the Yoplait Light

I regularly buy Yoplait yogurt and have checked for Red #40 and the other culprit dyes repeatedly. I was always happy that it was dyed with beet juice or other natural ingredients. So I was really surprised when I pulled out the Yoplait Light to notice that the red raspberry, blueberry and blackberry flavors all had red #40. I usually get the "original" but Ed did the shopping last time and picked up a bunch of "light" flavors. I'm probably going to take them in to work and give them away. I don't even want them in my refrigerator. I think I'll write to the company later today. At least I spotted it before feeding it to my children.
