A cautionary note: Often times a food manufacturing plant will contract with and produce multiple brands on the same equipment. For instance, I've seen brand name, store label, and bargain brand waffles come off the same line, with the same equipment and using the same ingredient stocks.
Of course, an industrial food plant isn't going to have a searchable presence online. It is quite difficult to find out exactly what any such facility makes, let alone what brands come out of it.
Of course I can't speak for every factory or brand, but my experience tells me to try and be cognizant of where bad products are made in addition to the brands themselves.
"Store brand" products are an IMO egregious case of this. Often it's utterly impossible to tell where a product has been manufcatured (as in: plant or factory), and somewhat ironically, correlated product recalls are often the only way of establishing where a store sources its "in house" brands.
The fact is that "in house" isn't, and what both the merchant and manufacturer are in fact preserving is the market ignorance of who the ultimate producer is.
