In warmer weather, pets and people often seek relief in lakes and ponds, but a Virginia Tech expert is warning about a hidden danger in the water.
Harmful algal blooms are a particular threat to pets.
“Toxic cyanobacteria, commonly known as blue-green algae, can be fatal to pets within minutes of exposure,” said Alexandra Reddy with the Virginia-Maryland College of Veterinary Medicine.
Pet owners should keep an eye out for thick scum or foam on the surface of stagnant water that has a blue-green, red or brown experience.
“You can’t tell if a bloom is toxic just by looking at it so it’s best to assume that all algal blooms are toxic to your pet, and don’t let them near it.”
The toxins produced by the bacteria target the liver and nervous system of animals.
“Ultimately, even just a few mouthfuls of contaminated water can be fatal to your pet,” Reddy said.
Symptoms of poisoning include vomiting, diarrhea, weakness, excessive drooling, seizures, muscle tremors and difficulty breathing. Symptoms can appear within minutes to hours of exposure, and in severe cases, “the only sign is sudden death.”
If you think your pet may have been in contaminated water, bathe them immediately with clean water to prevent them from licking the toxins, and seek immediate veterinary care.
The Virginia Department of Health issued numerous harmful algae bloom advisories last summer at Lake Anna. The first advisory was posted in June, and it was lifted in November.
To date, there have been no advisories issued for the lake this year. However, a possible bloom was reported at State Park Beach on Aug. 18. A sample was taken from Lake Anna on Aug. 19, and results are pending.
“Before visiting lakes or ponds, check for local warnings,” said Reddy.
