They are known to provoke a dermatitis reaction in harvesters of the cacti fruit. It’s spines are frequently an uncomfortable nuisance to unwary soldiers exercising in BATUS. We report two cases of particularly debilitating adverse skin reactions to the cacti spines that occurred during the 2010 Exercise Prairie Thunder season.
