I got a bag back in august of this year. does bromine not show up in their chemical content breakdown? I'm in the north east, so i'd be pretty sure that all the dow that was shipped up here since the beginning of 2006 would be new stuff and all the old stuff would be depleted no? the lot number on the bag is so hard to read, but i do not see the letters mentioned.
now i'm wondering if i should continue usage or not
