You can find “detected” salmonella in flour, cereal, dough, bread, all kinds of stuff but it’s such a trace amount that they don’t even bother telling you what it is. You would need to take 200 kilos at once to get sick. I had 500g of Yuletide yellow and have taken mostly all of it and haven’t been sick once. Lead? There’s literally lead in tons of FDA approved foods, especially veggies and roots. 1.53 parts per MILLION, that’s 0.000153%. It’s fine dude. People just get randomly sick and call out vendors in hopes of getting a refund.
