Lead content Kitchenaid KSM50 from Costco circa 1994

I have a Kitchenaid KSM50 from Costco circa 1994. It has aluminum alloy dough hook and batter paddle. I noticed my hook is rubbing the bowl sometimes and has worn slightly. So I looked for a replacement. I soon discovered there is lead in these parts! I was hoping to replace the hook with a stainless one. The ceramic coated  accessories also chip and have lead content. Does anyone have any insight?
