Why people don’t eat cashew nut in-shell?

Cashew plant contains powerful chemical irritants known as anacardic acids, so handling and eating raw cashews will cause the familiar itchy skin reaction in people sensitive to the chemicals. People who are sensitive to one plant in the family, for example poison ivy, are likely to be sensitive to others. Why isn’t there a reaction when people eat processed cashew nuts from the grocery store, then? The irritants are found in the shell oil, but not in the nuts themselves. Handling the shell or eating a nut with shell oil on it can cause a reaction.
