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.
Traditional cashew shelling process
About 11,80,000 tons of raw cashew nut seeds through 3650 cashew processing mills scattered in many states in India, according to researches, cashew nut in India is processing by hand cracking with traditional cracker and shelled by worker’s bare hands. Although some of cashew production factory has regulation on shelling that workers must wear special gloves during hand shelling, the irritant, toxic liquid exuded from the cashew shell can stimulate allergy reaction even cause heart attack.
