Veterinary notes and prevention
Cyanobacterial toxins can cause acute liver failure or rapid-onset neurological signs and respiratory paralysis depending on the species of algae. There is no specific antidote, so supportive care is critical and speed matters.
Prepare the information your vet needs
- For Blue-Green Algae (cyanobacteria) in Ponds and Lakes, report the exposure route: Drinking or swimming in water with a visible algal bloom, then swallowing water while grooming. Tell the clinic the time, possible amount and your pet's species and approximate weight.
- Photograph the packaging, ingredient list or plant if safe. Do not handle contaminated material without protection or delay the call to identify it perfectly.
- Keep other animals away from the source. An animal may appear normal before signs develop; do not wait for symptoms or calculate a home 'safe dose'.
- Follow the clinic's transport instructions. Do not give food, medicines or home remedies unless instructed, and take packaging with you if available.
