1. TBHQ is a chemical preservative. It's also a form of butane - yeah, lighter fluid. TBHQ is used to try and keep vegetable oils in processed foods from going rancid. It is carcinogenic (cancer-causing) and therefore toxic.
2. Toxic TBHQ has been found in Chicken McNuggets, microwave popcorn, pet food, soymilk, most fast food and many other processed foods. Check labels in the grocery store and steer clear of fast food restaurants to avoid it.
