The Mexican Breadfruit is part of the Araceae family, and more commonly known as the Ceriman, Swiss cheese or Hurricane plant. Fruit from this plant is edible if left to ripen at least 1 year. The stems, leaves and the unripened fruit of this plant contain insoluble calcium oxalate structures called raphides. Chewing or biting into these plant releases the crystals which penetrate tissue resulting in injury. When dogs or cats ingest insoluble calcium oxalate-containing plants, clinical signs may be seen immediately and include pawing at face (secondary to oral pain), drooling, foaming, and vomiting. Moderate to severe swelling of the lips, tongue, oral cavity, and upper airway may also be seen, making it difficult to breathe or swallow. Insoluble calcium oxalate-containing plants have a different mechanism of toxicity than soluble calcium oxalate-containing plants (e.g., star fruit, rhubarb, shamrock).
