The industry claims their salmon is ‘responsibly sourced’.
Don’t buy it.
We only get what the lice don’t eat.
The Truth About Salmon Farming
All Scottish salmon sold in supermarkets comes from overcrowded, filthy, underwater factory farms, where parasites and flesh-eating sea lice are endemic. Investigators have filmed fish with damaged and missing eyes and whole chunks of their flesh eaten away.
To treat infestations and disease, salmon are doused in toxic chemicals, including formaldehyde, azamethiphos, emamectin benzoate, and deltamethrin, which pollute Scottish lochs and kill wildlife. By 2017, at least 45 Scottish lochs had been polluted with chemicals, lethal to shrimp, lobsters and other crustaceans. A medium-sized farm can pump out as much effluent as a town of 50,000, making fish farming one of the most polluting agricultural sectors for eutrophication, beaten only by beef.
The fish are denied the natural diet that makes their flesh pink. And because no one would eat grey salmon, they feed the fish astaxanthin, a chemically synthesised pigment, and choose their desired shade of flesh straight from a colour chart. They dye them pink so they don’t die grey.
The Numbers Don’t Lie
of Scottish salmon in UK supermarkets is factory-farmed.1
companies account for nearly all Scottish salmon. None are British.
of formaldehyde was discharged directly into Scottish lochs by salmon farms in 2025.2
of antibiotics was used by the Scottish salmon industry in 2024.3
salmon died unexpectedly on farms before slaughter age, in less than three years.4

“Calling factory-farmed salmon ‘planet-friendly’ is like calling an oil spill a nature reserve.”
“Riddled with drugs, unable to move, and sitting in their own piss: at least hens in Magaluf feel the sun on their skin before getting slaughtered.”
“What they are doing to these birds is the stuff of nightmares.”
“The industry says, ‘Animal welfare is our top priority’. I don’t buy it. Those lame birds slumped in their own waste tell a very different story.”
“The chicken industry claims high welfare standards. I don’t buy it. Their farms make Victorian workhouses look like 5-star wellness retreats.”
“The industry claims that their chickens’ growth is natural. I don’t buy it. If my children grew that fast, I’d be strapping 40-stone toddlers into the buggy.”
“I looked up ‘humane’ in the dictionary and, I have to say, gassing didn’t come up.”
“Respiratory distress and fear. We don’t call that ‘humane’ in medicine.”
“Humane slaughter. That’s up there with ‘friendly fire’ and ‘voluntary redundancy’.”
“I’ve done some stupid things in my life. Walking into a gas chamber isn’t one of them.”
“Humane slaughter? Have a day off. That’s not humane, that’s marketing.”
