Prickly pear is the fruit of Opuntia cactus, a desert plant with spiny pads that is used in regional cooking and beverages. The fruit has sweet seedy flesh under a thick skin covered with spines and tiny barbed hairs called glochids. These external structures are the main physical hazard.
Prickly pear is sold fresh, juiced, pureed, and in syrups or candies. Cactus pads (nopales) are a separate edible plant part used in savory dishes. Processed products often include sugar and are not equivalent to plain prepared fruit flesh.
Safe prep requires complete removal of spines, glochids, peel, and as much hard seed material as practical. Incomplete cleaning can irritate the mouth or gut. This is a labor-intensive prep step and easy to underestimate.
For pets, avoid prickly pear unless it has been fully cleaned and peeled. If offered, use tiny plain seed-reduced pieces only.
