I have a similar concern. I'm not worried about trace amounts of carcinogens, but the Prop 65 warning that appears on the checkout page on Unjury mentions exposure to lead, which is something else entirely. From what I understand no amount of lead is safe for consumption. I'm not clear how they determine these risks...does the company just add a blanket warning to avoid lawsuits, or do they have actual reason to believe there is lead in their products? It's weird to put that pressure on the customer. I don't want to be a paranoid alarmist, but it's like, why would I buy a food if the grocer is telling me it's poisonous? I wish they explained better or just did whatever they need to do to assure to avoid the risk. I saw this warning after adding Whey Protein Powders to my cart and going to checkout. I guess I'll just avoid that brand?
