SPCA is urging pet owners to take extra precautions when using or disposing of used Rapid Antigen Tests (RATs), as some
may contain a substance that can be toxic to animals.
The warning comes after Australia’s Animal Poison Helpline experienced an increase in calls from concerned pet owners
whose animals, particularly dogs, had ingested the substance.
Some RATs contain the chemical sodium azide, which is added as a preservative. Although sodium azide is highly toxic,
each test contains a very small amount. While the tests pose no real risk to humans, smaller animals or pets that ingest
the contents of multiple tests are at greater risk.
While RATs are only just beginning to be more widely used in New Zealand, SPCA is asking pet owners not to leave the
tests where their animals may be able to reach them.
“Many pet owners will know how easy it can be for our animals to get into things they’re not supposed to, which is why
it’s important for us to make sure we dispose of these tests properly and responsibly,” says SPCA Scientific Officer Dr
Alison Vaughan. “Sodium azide is toxic and small animals, or those who ingest multiple tests, could be at risk of
poisoning. While sodium azide is likely to cause only mild, self-limiting symptoms such as hypotension (low blood
pressure) in larger dogs, smaller animals may experience more serious symptoms.”
Anyone who is concerned that their pet may have accidentally swallowed or chewed one of these vials should contact their
vet or the Pet Poison Helpline (0800 869 738) immediately.
