Beachgoers in Cape Town are being urged to stay alert after highly toxic puffer fish washed ashore at two popular beaches. The City confirmed that the fish were spotted at Muizenberg Beach and Camps Bay on the same day, raising concerns for both the public and pet owners. Why puffer fish are dangerous Puffer fish are known to carry a powerful toxin called tetrodotoxin, which can be deadly if ingested.
Even small amounts can pose serious health risks to humans and animals. While the fish may appear harmless once washed up on shore, officials warn that they remain dangerous and should not be touched or handled. According to the City, the sightings are linked to current large swell conditions along the coastline.
These ocean patterns can wash marine life, including puffer fish, onto Cape Town’s beaches. Officials say this is a natural and relatively common occurrence during periods of rough seas, but it still requires caution.

Dogs are at particular risk, as they may try to sniff, bite or eat the washed-up marine life. Ingesting even a small amount can be fatal. The City has stressed that puffer fish can appear at any time and at various locations along the coast while conditions remain rough.
