  • • If you are unsure if the ingested plant is Zebra cactus or a potentially toxic lookalike species

Prevention

  • • Clearly label all houseplants and garden succulents to avoid misidentification as edible plants
  • • Keep large quantities of succulent plants out of reach of grazing livestock to prevent overconsumption
  • • Verify the identity of any succulent before allowing pets or livestock access to it
