heavy metals, potassium chlorate
Toxicity to pets
Matches are dangerous to pets, as they contain hazardous chemicals such as potassium nitrate, which is an oxidizing agent. Matches can also contain charcoal or sulfur and coloring agents, which are potentially dangerous heavy metals. When ingested, pets can develop gastrointestinal issues like vomiting, a painful abdomen, and bloody diarrhea. The severity of pet health issues resulting from ingestion will depend on the amount of matches that was ingested. Pets ingesting large amounts can suffer tremors or seizures, along with acute kidney failure, bone marrow changes, shallow breathing and jaundice, which is yellowing of the skin.
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.
