Why are beach toxins dangerous?

Blue-green algae can cause liver and kidney damage, while shellfish toxins can lead to neurological symptoms.

Pets are more susceptible to these toxins due to their curiosity and playfulness.

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.

  • Vomiting and diarrhea
  • Lethargy and weakness
  • Increased thirst and urination

What to do right now

  1. Avoid beaches with known toxic algae blooms.
