Dangerous cyanobacteria lifting off the bottom of St. John River
The bacteria was responsible for the death of three dogs in 2018

A University of New Brunswick biologist is trying to get the word out about a dangerous toxin in the St. John River between Fredericton and the Mactaquac Dam.
Cyanobacteria die in the winter months but come back in small pockets on the bottom of the river as the weather warms up.
Now they cover almost 90 per cent of the river floor in some parts of the St. John River, says biologist Janice Lawrence.
She and her colleagues at the Canadian Rivers Institute sent a warning to the Department of Environment this week about a massive lift-off of the bacteria in the Fredericton area.
Once the bacteria cover a larger area, they thicken into pads that are more likely to be swept down the river with heavy currents and lifted off the bottom of the river. Once a pad of cyanobacteria is on the surface, people are more likely to come in contact with it and eventually the cyanobacteria can end up on shorelines.
"That's when there's a greater chance individuals or dogs may come in contact with it," Lawrence told Information Morning Fredericton on Thursday.
Researchers only became aware of the bacteria in the river in 2018 after three dogs died shortly after coming in contact with the water. A fourth dog died in 2019.

Cyanobacteria is different from blue-green algae and can be dangerous to humans too, especially children who play in the water and are more likely to ingest it.
The bacteria can be brown, rusty, burgundy or chalky.
"This type of bacteria produces a neurotoxin which actually causes paralysis of the muscles associated with breathing," Lawrence said. "The neurotoxin will actually cause suffocation and death if it's ingested in large enough quantities."
Lawrence said there is no evidence to suggest that man-made materials, such as fertilizer washing into the river, have any impact on the amount of cyanobacteria growth.
However, the bacteria grow better in warmer temperatures and because of global warming, larger amounts of the bacteria are being found.
Lawrence said locally researchers are hoping to figure out other things that may be helping the bacteria's growth.
"We would really like to try and see if there are factors that are enhancing the growth of this thing and in the meantime being really vigilant with individuals or animals that are going to be more susceptible to being exposed to it."
She said she knows some people are worried but suggested they just treat cyanobacteria as they would other dangers present in the environment.
"If you go out into the woods and you know there will be bears there, you just take precautions," she said. "I would take the same approach with the river with anywhere else."
The New Brunswick government has guidelines on its website for safe water activities, including always checking the water for signs of algae, being careful not to ingest river water, and showering after swimming.
Information on cyanobacteria advisories can be found on the government website.

I think I'll skip swimming along the river bottom...50M down...for now...seriously, covid is ravaging the world including cats and this is a story?

Of course this is a story!
This bacteria can kill a child. The river isn't so deep everywhere. People need to know.
sheesh.

Well it’s official. The river is dead. Keep your pets and kids out of it.

It is the Saint John River NOT St John! Hire someone who knows some of Canada's geography, CBC!

Reply to @Larry Larson: It is the Wolastoq River

First, as Theresa says, it's the Wolastoq River.
Second though, the Saint St. thing was only about the city, not the river.

John Grail is the real expert on blue green algae. CBC should interview him. Who needs scientists when there is the internet.
John Grail
Reply to @Jeff
LeBlanc: Please read the linked CBC article where this same expert
mentions that algae blooms are caused by run-off...Willful ignorance is
your strong suit...
John Grail
Reply to @Richard
Bend: Yeah, because I am saying let's eat our fecal matter...nice straw
man...more fallacies. Can anyone even posit a legitimate argument?
John Grail
Reply to @Jeff
LeBlanc: Speaking of experts, how much research have you done? Just by
looking at twonof the links in the article would prove my point. I mean I
know it's hard to admit you're wrong:
"Although nutrients are naturally occurring in a lake and are needed for plant and animal life, too much phosphorus and nitrogen can cause problems by offsetting the natural balance of the lake. • These problems arise or are compounded when storm water, agricultural runoff, industrial and wastewater effluent, faulty septic systems and lawn fertilizers find their way into the lake."

What global warming.
I keep waiting, but we've got the same bloody rotten weather we've always had.

Robertson: I know the fish hatchery in mactaquac had water chillers
installed in 2003...300k +/-...for future global warming, as the river
was going to heat up they said (so that study was likely from the
2000's)....it was never used, as the water temps are still good to grow
fish.

We've spent / wasted a lot of money on what's 'projected' to happen.
Haven't seen any of it yet; especially water temperature.

The denial is strong in some.
Climate change is a fact. It's okay that you cherrypick, but that doesn't change the actual facts based on real data.

Reply to @Tristis
Ward: I ain't denying that there is a change in the weather However like
many others it is the cause of it is that I dispute with the people who
merely wish to raise taxes in order to stop it That is well within my
rights to do so Correct???
