Sounds like you should stay at home and grow your food on your own farm. Lots of cooking tools use hi-tech research, from non-stick pans to heat resistant spatulas. I understand your concern, but there's no need to freak out over technology applied to food. There are more opportunities for less visible man-made technology to become dangerous in non-culinary situations, such as your home's insulation, or materials used in microchip packaging. There's less regulation there and higher chances of "science" having ill effects on you. If you don't live in California, there's a higher chance that you could be buying non-RoHS compliant manufactured goods that can be more hazardous to you than any culinary equipment.
