Calling shenanigans — again — on Morton’s junk graph

Alexandra Morton has decided to make 2014 the year of the Salmon Food Scare, and she’s trying as hard as she can to stir up the masses using half-truths and emotion.

She’s no doubt trying to recreate the panic from 2004, when one highly-publicized study was used to suggest farmed salmon was dangerous to human health. Ah the good old days, eh Alex? When the gullible masses would believe anything you said without checking your claims? Must be tough these days, judging by the “DONATE NOW” button on every one of your websites. 

For a good overview of how that 2004 panic all shook out, including an enlightening look at the millions of dollars invested in slagging farmed salmon, we recommend you read this opinion piece by Vivian Krause.  

Oh, and by the way, there’s no reason to be concerned about dioxins or PCBs in any food sold in North America. None.

Eat a balanced diet, get some exercise and be excellent to each other and you’re shiny.

But that’s not stopping Morton, who knows how to play on people’s fears like a cheap fiddle.

A while ago we blogged about a ridiculous graph she is using to try and claim that farmed salmon contains dangerous levels of dioxins.

Apparently, ashamed to have been caught in the act of deliberately misrepresenting the facts, she has revised this graph with an explanation in the fine print on her new website. She says:

Please note the source data for salmon is provided in pg/g wet weight, while the other values were provided in pg/g fat. NIFES reports farmed salmon is 15.6% fat and so the conversion to pg/g fat = 41.6

Yeah, no. This is just stupid, Alex.

Wet weight is a common distinction made in weighing fish, because so much fish sold is smoked, cured, salted or dried. Wet weight is merely a measurement of fish with the water content in, i.e. before being processed. The non-fish products on this list are always weighed with their water content included: their default measurement is wet weight.

What you’re doing here is like assuming that if your car can go 160 km/h before the governor kicks in, and the speed limit is 80 km/h, it should only take you half an hour to get where you’re going.

But since you aren’t inclined to provide people with facts, we’ll do it for you.

Here’s a comparison of the limits on dioxins in food set by the EU, versus the amounts that are actually in said food.

Facts hurt, don’t they Alex. There’s no reason to avoid any of these foods because of dioxins.

Want to check our math? Feel free. Here’s the data table we used to make this graph, complete with comprehensive citations.. Which is more than activists like Morton will give you.

Oh, and by the way, if the anonymity on our blog bothers you? Feel free to check all the links in the document above and retrace our steps. Thinking for yourself: does a body good.

Activist math, contaminants and the art of fear

We’ve been sitting on this one for a while because we wanted to see how far it would go. Apparently, our favourite scaremongerer is pretty serious about it so we figured it was time to expose this.

In a poor attempt to scare people about food contamination, Alexandra Morton has created a graph that people might assume shows that farmed salmon is contaminated with PCBs.

Oooh, scary, right? Two things though.

1) These numbers, as shown in the EU regulation cited by Morton as the source of information for this graph, DO NOT represent ACTUAL amounts of dioxins and PCBs in ANYTHING. They are limits set by the EU on what is a safe amount in those foods. Morton neglects to point this out, giving a false impression.

2) This “41.6” number on Morton’s graph comes out of thin air. The actual limit for salmon and all other fish, as set in the EU document source for the other numbers on the graph, is 6.5.

Check it for yourself, it’s on page 4.

Because 6.5 doesn’t have the sort of shock value Morton was hoping for, she did some of her own math and came up with a greater number, conveniently forgetting to show where in the world this number comes from, and also neglecting to explain that these numbers represent the limits set by the EU, not actual test results.

But that’s all boring, right? Who cares, Morton raises a valid point, a scary story about how farmed salmon are more contaminated, right? Who cares that she just made up a number and misrepresented what her source actually says, she’s just getting the truth out there right? We’re sure someone will comment here saying something like that.

That’s the art of fear in action, and Morton is damn good at it. She starts with a scary story, and then manipulates data to make it look like science is on her side. By the time people like us come along and pull back the curtain, it doesn’t matter because people really want to believe in Oz.

People believe in stories, not facts.

But we’ll keep bringing our readers the facts, in the hopes that they will learn how to pull apart these anti-salmon farming stories and see that they are something much more vulgar: manipulative lies.
