The bromate ingredients are only dangerous if the factory fucked up during production as well. If they're doing their job correctly, there is no bromate in your food.
It's sort of like how you don't have to worry about food poisoning from chicken when it's cooked through, even though it's not recommended to risk eating the raw stuff.
No idea about the other two banned ingredients, but the risk seems pretty low for these at least. I wouldn't bother throwing food away over their presence, personally, but that's just me.
