I dont blame anyone for avoiding chemicals and exposure / ingestion of heavy metals as much as possible, but the Cause Cancer in California really does not give you all tge info one is required to weigh the associated with a product, it will not give you the chemical of concern or the quantity of mercury in that tin of tuna, and that does not mean you are not buying an item that might cause you harm if it does not have that warning, its a catch all or a red flag to do further investigation depending on the item. Its like the "idiot light" in a car... it can indicate "something" but what lol
