The Dangers Of Blue-Green Algae

You might be aware of a threat that many lakes and ponds conceal. Cyanobacteria, commonly referred to as blue-green algae, is a bacteria species that flourishes in warm water environments. The toxin it releases can be extremely hazardous, posing a serious threat to both humans and animals. This is important information that all pet owners should be aware of, especially if they frequently take their dogs swimming in freshwater. Continue reading to gain valuable insights from a Marshall County, MS veterinarian regarding this hazardous toxin.

What Exactly Is Blue-Green Algae?

This particular strain of algae poses a significant threat due to its production of a specific toxin. Blooms can happen at any time when the average water temperature exceeds 75 degrees, as this is when numerous bodies of water become abundant in nutrients. The summer months, especially around and just after the dog days of summer, can be particularly hazardous.

Cyanobacteria is commonly found in shallower lakes and ponds. Under favorable conditions, blooms have the potential to grow rapidly.

Is Blue-Green Algae Very Dangerous?

Blue-green algae poses a significant threat to the health and safety of both humans and animals. Exposure can result in symptoms such as diarrhea, nausea, vomiting, skin rashes, eye and throat irritation, and respiratory distress. In addition, it can result in severe neurological issues and potential liver failure. Exposure to or ingestion of significant quantities of the algae can ultimately be fatal. Regrettably, there is no antidote available.

Both dogs and livestock are especially vulnerable to the dangers of drinking contaminated water, as they may unknowingly consume a significant amount before you have a chance to intervene.

Is Swimming In Blue-Green Algae Safe?

Under no circumstances is this safe. There is a potential risk involved in this situation as blooms can sometimes be present but remain undetectable. It is important to exercise caution and thoroughly research local resources, even if a lake or pond appears to be safe. Only swim in areas that have been cleared and are designated for swimming.

How Do I Determine Whether Blue-Green Algae Is Present?

You can usually identify and detect blue-green algae blooms based on their appearance and odor. There is a valid reason why cyanobacteria is commonly called blue-green algae. The blooms frequently resemble the color and consistency of pea soup or green paint. They frequently release an unpleasant, swamp-like scent.

However, it is important to consider more than just appearances. Smaller blooms may not be easily noticeable without close inspection.

What Are The Warning Signs Of Exposure In Dogs?

Keep an eye out for certain signs. These may include panting, respiratory issues, vomiting, diarrhea, dizziness or disorientation, and excessive drooling. Severe cases may lead to seizures. If any of these warning signs appear in your furry friend, reach out to your veterinarian or an urgent care pet clinic immediately.

As previously stated, there is no known antidote. However, providing adequate supportive care can have a significant impact. Seek additional information from your Marshall County, MS veterinarian.

How Does Blue-Green Algae Make People Sick?

Drinking contaminated water is a common source of illness for dogs, although it is not the sole cause. Toxins can also be ingested by people and pets through their skin or by inhaling water droplets or mist. Swimming isn’t the only danger: summer activities like tubing, water skiing, swimming, floating, or boating can potentially expose you to contamination.

Pets can become ill from being submerged in water, but also just by splashing and playing. Additionally, they may later groom themselves and remove the cyanobacteria from their fur by licking it.

How Can I Determine If A Lake Is Safe For Dogs To Swim In?

If you detect a swamp odor or observe the presence of green scum, the lake is not safe. However, as previously stated, the bloom may not be visible. Be sure to keep an eye out for posted signs, as local governments often put up notices once blooms have been confirmed.

Another resource you can utilize is the HAB (Harmful Algae Blooms) map, which is available at this link. This website offers comprehensive updates on blue-green algae blooms in all states.

What Should Be Done If A Pet Comes Into Contact With Cyanobacteria?

Start by giving Fido a thorough bath to get rid of anything that may still be on his fur, and contact your vet or an urgent care veterinary clinic. Symptoms may not appear immediately, but don’t wait: the sooner your pet can get supportive care, the better. 

How Long Do Most Blue-Green Algae Blooms Last?

An individual bloom has a relatively short lifespan of about one to two weeks. However, under favorable circumstances, they can quickly be replaced by another. Lakes can remain contaminated for extended periods of time, ranging from weeks to even months. This typically occurs during the transition from summer to fall.

Can Boiling Water Get Rid Of Blue-Green Algae?

While boiling is effective at eliminating live bacteria and microorganisms, it does not eliminate cyanobacterial toxins. If you enjoy camping with your furry friend and frequently need to boil water from natural sources, be very careful here. 

What More Can I Do To Ensure Fido’s Safety At The Lake?

There are other potential dangers that can be found in lakes besides cyanobacteria. Swimming can be a source of great enjoyment for Fido, but it’s important to remember that not all dogs are suited for it. If your furry friend happens to be a brachycephalic breed or faces mobility challenges, it would be more beneficial for them to enjoy some water play in a kiddie pool. Even tiny dogs can be at risk in water as they can easily find themselves in water that is deeper than they can handle. If you have any doubts about whether swimming is appropriate for your dog, it best to talk to your Marshall County, MS veterinarian.

Always closely monitor Fido while he is in the water. Also, be mindful of the locations you choose to take him. Avoid areas with blue-green algae blooms, as well as places with steep drops, heavy wakes, or strong currents. When bringing your dog to a pool, it is important to promptly familiarize them with the location of the stairs.

Lastly, keep your dog from drinking water from lakes, ponds, or puddles. Aside from the potential danger of cyanobacteria, Fido may also be at risk of contracting parasites like Giardia. The Leave It command can be helpful here.

In Conclusion: Cyanobacteria, commonly known as blue-green algae, can be found in various lakes and ponds during the summer months. These algae can produce toxins that are harmful to both humans and aquatic life. This poses a significant threat to pets and livestock. Indeed, exposure can prove to be lethal for our beloved dogs. Understanding the hazards and being able to recognize and steer clear of harmful blooms is crucial for pet owners.
