Protecting Pets from Toxic Algae Blooms This Summer
PULLMAN, Wash. — With the arrival of summer heat, the risk posed by toxic blue-green algae blooms is becoming a significant concern for pet owners throughout the Pacific Northwest.
The Dangers of Blue-Green Algae
Exposure to blue-green algae, scientifically known as cyanobacteria, can be fatal to pets in as little as 15 to 20 minutes. Animals can come into contact with these harmful toxins simply by interacting with contaminated water bodies such as lakes, ponds, rivers, streams, or even backyard decorative pools and neglected swimming pools.
“Just retrieving a ball or stick from contaminated water or licking algae off their fur can lead to tragedy,” stated Dr. Chelsea Sykes, a diagnostic toxicologist at Washington State University’s Animal Disease Diagnostic Laboratory.
Understanding Cyanobacteria Blooms
Cyanobacteria are microscopic organisms that thrive in warm and stagnant waters rich in nutrients like phosphorus and nitrogen—frequently enough stemming from agricultural runoff. These blooms typically occur between late spring and early fall and may appear as thick green sludge or resemble pea soup on the surface of still waters. However, they can manifest in various colors.
Identifying Potential Risks
The presence of dead fish or birds near a water source may indicate an algal bloom; though, it is indeed impossible to determine if the bloom is toxic without specialized testing.during warmer months, it’s wise for pet owners to assume that all still or slow-moving surface waters could be hazardous.
“Unfortunatly,you can’t tell if a bloom is dangerous just by looking at it,” Sykes emphasized. “That’s why we always advise: ’When in doubt, stay out.'”
Symptoms of Algal Poisoning in Pets
If pets show signs of exposure to harmful algae toxins—such as vomiting, diarrhea, lethargy, disorientation, pale gums, skin irritations seizures breathing difficulties—it’s crucial for owners to seek veterinary assistance immediately. They can contact their veterinarian directly or reach out to the WSU Veterinary Teaching Hospital emergency line at 509-335-0711.
“Once symptoms appear after exposure occurs,” Sykes warned,”the time frame for effective treatment becomes very limited.” Prompt medical intervention offers pets their best chance for recovery.
Preventative Measures Against Exposure
Sykes advises avoiding any body of water that appears discolored or resembles spilled paint; keep pets away from unknown sources; and rinse them thoroughly with clean water if they do get wet. It’s also essential to prevent animals from licking their fur afterward.
“The best defense against these dangers is prevention,” Sykes noted. ”Always keep your pets leashed near open bodies of water and exercise caution—it simply isn’t worth the risk.”
