Death of 3 Dogs After Drinking Water from Kent Lake: Investigation Begins

Click For Summary

Discussion Overview

The discussion revolves around the deaths of three dogs after drinking water from Kent Lake, with participants exploring the potential causes, particularly focusing on the role of blue-green algae and associated toxins. The conversation includes speculation about the timing of the dogs' deaths, the reliability of water testing, and previous incidents related to similar algae contamination.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants propose that the green-blue algae hypothesis could explain the rapid deaths of the dogs, while others question whether symptoms would have appeared before death if toxins were present.
  • There is mention of anatoxin-a, a potent neurotoxin produced by certain blue-green algae, which could lead to quick fatalities.
  • Concerns are raised about the adequacy of testing drinking water for all potential contaminants, including algae-related toxins.
  • Some participants express skepticism about the feasibility and cost-effectiveness of comprehensive water testing.
  • A later reply indicates that it has been confirmed that blue-green algae were present in the lake.
  • One participant recalls previous incidents of similar nature in England but does not provide details.

Areas of Agreement / Disagreement

Participants express a range of views regarding the cause of the dogs' deaths, with some agreeing on the potential role of blue-green algae while others remain uncertain about the implications of the findings. The discussion reflects multiple competing hypotheses and does not reach a consensus.

Contextual Notes

Limitations include the lack of detailed information from veterinary and water reports, as well as uncertainty regarding the dogs' activities prior to their deaths. The discussion also highlights the challenges in testing for all possible contaminants in drinking water.

Could be.
But the story is kind of vague and sparse of information.
The water report and veterinary report have not been done or completed yet, so it is premature to pin-point.
Still they are relying on caution that it could be from drinking the water.
We obviously do not know where the dogs have been in the hours or recent days before the deaths and illness.

Still, if contaminated, the toxity of the bacteria can shows symptoms quite quickly.

Does the green-blue algae hypotesis fit with the nearly instantaneous death of the dogs that drank the water?

Cyanobacteria is poisonous to dogs, but if there was toxic bacteria in the water, wouldn't the dogs have had symptoms first? The article just says that they "died shortly after" being in the water.

I would bet on anatoxin-a - a powerful neurologic toxin produced by - can be fatal in a matter of a few minutes.

https://en.wikipedia.org/wiki/Anatoxin-a

These genera blue-green alagae have been shown to produce Anatoxin-a:
Anabaena
Aphanizomenon
Cylindrospermum
Microcystis
Oscillatoria
Planktothrix
Raphidiopsis

Oscillatoria and Anabaena are goto lab fare in freshman Biology - prepared slides are best.

I wish the article stated some more details on the dogs' death.

Anabaena is beautiful!
 
Thank you all for your replies.
If the algae-related toxin hypothesis is true, one has to hope such organisms don't end up in drinking water reservoirs.
I seem to understand that the conditions for their growth are such that they could hardly thrive there.
Some posters in the Yahoo thread say drinking water is tested for contaminants before distribution - but can you really test it for 'everything'?

If you're talking about bacteria, of course, with DNA tests.
 
Indeed.
But I meant 'can' as in 'are we going to spend the money to do it', not as in 'is it technically possible'.
Well, let's hope we don't have that problem in the first place.

Well, it's not exactly "cheap" (depends on your standards), but the technology has been out there for quite some time and DNA testing can be done quite efficiently. If contaminated water becomes a serious problem, as suggested in the references you linked to, then there is no reason why they shouldn't test the water. It's really just a matter of whether it is necessary or not.

If you are in the UK then your drinking water is tested regularly, with all the results being recorded and collated by the Drinking Water Inspectorate, which also has advice for consumers on its website.

I remember there have been some previous such cases, also in England. I cannot recall detail at this moment, if it comes back I will post it.
