Not-so-fun thing I was told about commercial truffle searchers: many of their dogs die of breast cancer. Truffle volatiles work as a pheromone, wreaking havoc to the bitches endocrinal system.
My brother brought this piece of info from Istria, where he accompanied truffle hunters. He brought back some, and I have to say it’s one of the weirdest things to pay such a price for. It isn’t unpleasant, but the sulfuric component is weirdly strong.
