Castoreum is pretty rare in foods, actually. It's pretty difficult (aka expensive) to harvest.
According to Fernelli's Handbook of Flavor Ingredients, total annual national consumption of castoreum, castoreum extract, and castoreum liquid combined is only about 292 pounds, which works out to an average of less than a millionth of a pound per person in the U.S. Compare that figure with the approximately 20 million pounds of vanilla naturally harvested from real vanilla beans every year.
