Not food, but I got a new chain for the bicycle today, and they are also teflon-lubricated when you get them (a workshop installed it). It's PFAS everywhere.
Of course there are plenty of commercial bike lubes that come with Teflon aka PTFE mixed in.
Completely unnecessary, there's a movement to move towards simple paraffin or natural waxes in the cycling community. In fact, wax wears chain less via less contamination and is vastly more efficient than many of the teflon drip lubes.
