Animals/Human Poisoning:

Note: When an animal is listed without additional information, the literature (as of 1993) contained no detailed explanation.

Humans

General symptoms of poisoning:

aphonia
blistering
hoarseness
mouth, irritation of
urticaria

Notes on poisoning:

Chewing the leaf causes severe pain and irritation, along with blistering and edema of mouth tissue. Hoarseness and loss of voice can also occur. The insoluble oxalates do not cause systemic poisoning in humans (Lampe and McCann 1985). Ingesting the ripened fruit can cause rapidly developing urticaria (hives) in sensitive individuals (Mitchell and Rook 1979). The ripe fruit is edible but is not normally produced indoors in Canada.
