Reply To: Reliable Hashgacha?

I’m just curious why Sun Maid raisins (and perhaps other products) are accepted, even with the Triangle-K hechsher. So much so that they are used in Kellogg’s Raisin Bran (and perhaps Post Raisin Bran), which come with more accepted hechsherim? This is something that has confused me for a long time.
