How aluminum phosphide poisons pets
When ingested, aluminum phosphide tablets or pellets react with stomach acid to release phosphine gas, which shuts down cellular energy production in the heart, liver, and lungs.
The bait is usually grey or black granules or pellets packed in small foil or plastic sachets—often found near food stores, grain bins, or in agricultural settings.
Owners may not realise the danger because the product is sometimes sold as a professional-grade fumigant rather than a typical home rodenticide.
The smell of garlic or decaying fish from phosphine gas can be detected on the pet's breath, but by then the toxin has already caused catastrophic cellular damage.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of aluminum-phosphide-rodenticide poisoning
- Violent vomiting within minutes, sometimes with blood in the vomit
- Collapse and inability to stand within 30 minutes to 2 hours
- Gasping for air, laboured breathing, or frothy pink fluid from the nose
- Weak rapid pulse followed by cardiac arrest
- Garlic or rotten-fish odour on the breath that owners notice when holding the pet close
What to do right now
- Call your vet or the nearest emergency animal hospital immediately and tell them you suspect aluminum phosphide exposure so they can prepare antidotes and supportive care.
- Do not induce vomiting—you risk exposing yourself and your pet to phosphine gas released in the oesophagus and mouth.
- Take the product packaging with you to the clinic so the vet can confirm the active ingredient and dosage.
- Keep your pet calm and in a well-ventilated area while you arrange transport; avoid close face-to-face contact if the gas odour is strong.
- If your pet is unconscious, place them in the recovery position on their side and keep the airway clear.
