Toxicity to pets
The sweat pea, or Lathyrus, contains amino acids and a toxin called aminoproprionitrite. When ingested, it can cause neurological and musculoskeletal signs including weakness, lethargy, tremors and seizures. Typically, this is more commonly seen in large animals chronically grazing on sweet pea.
The content of this page is not veterinary advice. A number of factors (amount of substance ingested, size of the animal, allergies, etc.) determine what is toxic to a particular pet. If you think your pet has eaten something potentially toxic, call Pet Poison Helpline or seek immediate veterinary treatment.
