Nottawasaga contaminants issues, Eulogy for the Pike Infested Swamp

I really doubt that the locations (coordinates) indicated in the Guide always reflect the actual sites where fish samples were taken. Sure, for the small lakes it is obvious, but for the big lakes and rivers I am pretty sure it is not.
Then, we don’t know when the samples were taken. They say fish is tested “periodically” but don’t disclose what it means. I had contacted MECP asking them to indicate the date of the sample for each location but I really doubt they are going to listen.

What do I mean by ‘Common sense’? Try your best to eat fish from the most clean location, try not go over the limit indicated in the Guide. Special concern is for pregnant women and children, but much less for older folks.
But you need to understand that we still need to eat fish, as we need all these omega 3,6 etc. And if you buy fish in the store or use supplements (with all raw materials most likely coming from China or India) you just don’t know what you are taking.
It is pretty much the same as people here some 20 years ago, before the testing program started, were fishing and eating the fish without any idea what crap was in it. But - sure enough - at that time the level of mercury and PCB was higher than now (PCB was banned in 1970-1980, as I recall).
People have lived their lives and many still live and are happy (or not).
No one has a solution here, humans have contaminated the planet extremely heavily but life is going on…

It's pretty much about this joke:
Life is dangerous because you can die.
But what options do we have?

LOL.....Agreed.

That’s exactly the opposite of what I was saying. Unlikely you have any idea where this Filet-O-Fish came from and how much contaminants it contains.

You are correct that PCBs were banned, but in Canada there is still unhealthy levels in many areas because of the way they were disposed. Other countries still use PCBs and travel through the air and land wherever the jet stream drops them in Canada. There are still PCBs in older buildings etc. in Canada. Mercury levels are lower in many areas than they were 50 years ago. But in some areas, Mercury levels are rising. Also water testing in the Great Lakes etc. for chemicals started when I was around 10 years old. That was 50 years ago, not 20 years ago. And Mercury is still at the top of the list for testing.We knew way back then that eating fish and animals that contained contaminants was bad for our health. So some chemicals were banned or used in less concentrations. Then we invented even worse toxic chemicals like PFAS (Forever Chemicals) now many of those are being banned. Again, you are right that humans have contaminated our world. Some are trying to clean it up, but many are still finding short cuts that have consequences. Can we save the planet? Probably not. But I think it will last at least another 500 to 1000 years. Then it might just pop like a balloon. The optimistic thought is maybe we can save it. I have always been an optimist. I am a fisherman. I believe, I believe, I believe.

LOL. Couldn’t have said it better

I think most anglers believe that if the contamination were really serious, there would be obvious public warnings—signs posted, press releases, news stories. But that’s simply not how it works in Ontario.

Instead, the Guide to Eating Ontario Fish (available online) is considered the official source. The government believes that publishing the data there is enough—and the responsibility falls to the angler to find, understand, and follow the Guide’s advice.

So let’s take a look at what it actually says.

At the station listed as “Nottawasaga River (44°28'57"N, 79°59'56"W)”, children and women of childbearing age are advised to eat ZERO meals per month of:

• walleye
• yellow perch
• rainbow trout
• smallmouth bass
• black crappie
• northern pike
• rock bass
• pumpkinseed
• redhorse sucker
• white sucker
• common carp
• chinook salmon

In short: 12 of the 13 species tested at this location are now classified as “do not eat” fish for children and women of childbearing age.

In the majority of cases, this is because of PFAS contamination—a class of industrial chemicals linked to immune suppression, hormone disruption, and reduced reproductive success. The source is well established: firefighting foam from the training school at CFB Borden, which flows into Bear Creek, then into the Pine River, and then into the Nottawasaga River. The full contamination pathway is over 46.6 km long, extending through Jack’s Lake and continuing downstream.

The Guide is telling you that these fish are not safe to eat—not even a few times a year—for children or women who are pregnant or could become pregnant. That’s not just a minor advisory. It’s a serious warning buried in a spreadsheet.

“With great power there must also come—great responsibility.”

Anglers have the power to bring home food for their families. But with that comes the responsibility to make informed choices—especially when feeding vulnerable people.

You don’t have to take my word for it. Just read the Guide. The facts are there for anyone willing to look.

Last 2 sentences pretty much covers it. "I don't know" or "nobody told me" is pretty much ignorance. Sounds like those that buy a new car and don't know how it works but they give you a 300 page explicit manual.

I was thinking this topic is over for me but could not resist and did a quick search in PubMed. But I was more interested in PCBs, not in PFAS because … oh, well that’s another story,… Sorry for cluttering the initial topic but it is related.

We went GB fishing yesterday and for the first time in two years we got a salmon. Unfortunately, it was huge. 15 lb, 85 cm. If I would be alone I would release it without any attempt to bring it to the boat. But as I humbly asked my wife “Let’s release it”, she was vigorously decisive: “I won’t ever go fishing with you if you release it”.
Ok, we took it and we are going to eat it. A lot.
So, this is my “common sense’. I know it’s apparently not very good for our health even though it's not dramatically destructive. But I want to enjoy my lifestyle, I want my wife to go fishing with me and I do accept some health risk for that.

Now, come back to my quick search about PCB.
I was … not entirely surprised but rather surprisingly found info to confirm that I was long thinking about.
This study
https://pmc.ncbi.nlm.nih.gov/articles/PMC1566611/
found that:
Comparisons with available international data on adipose tissue levels reveal that the organochlorine body burden in the Inuit population of Greenland is presently among the highest resulting from environmental exposure.
Imagine: these folks in Greenland are living in the apparently cleanest and least polluted environment in the world and still consume a lot of crap.
And you are talking about Filet-O-Fish from McD's!
