An article in the Times dining section takes a slap at farmed salmon:
even if some fish farms are exploring more-sustainable methods, it is well known that aquacultured salmon is an environmental danger and potential health hazard. A quick Internet search will give curious cooks more information on the topic. It's enough to put you off your dinner, and may well make you a wild-salmon convert.
Not an actual health hazard, but a "potential health hazard."
This sort of health journalism is likely to do more harm than help.
The Times applies it inconsistently and hypocritically. For example, opposite the page with the Times article warning of the perils of farmed salmon is a large photo of "berry summer pudding" topped by a scoop of what appears to be vanilla ice cream. The recipe calls for "10 to 12 slices of soft white bread" as well as "Heavy cream or ice cream." That Times article makes not a mention of the "potential health hazard" posed by the sugar in white bread and ice cream or by the cholesterol and saturated fat in ice cream. Elsewhere in the dining section there are pages of wine and cocktail coverage without any mention of the "potential health hazard" posed by alcoholism or drunk driving.
Scaring people away from farmed salmon is especially irresponsible considering that, given the cost, for a lot of people the alternative to farmed salmon may not be wild salmon but some other food that is potentially even less healthy, like red meat, or berry summer pudding covered with ice cream.
If the Times really wants to warn readers of a health hazard, the responsible thing to do would be to consult some peer-reviewed scientific studies or reputable nutritional authorities. Telling readers to do "a quick Internet search" is a default; the Internet is full of unreliable and alarmist information about all sorts of things, driven by all sorts of political agendas. The Times is supposed to help readers sort through that, not just send the readers out to do so on their own.
I try to be reasonably careful about these matters, and I eat a lot of fish, and I've concluded that a small portion of farmed salmon once or three times a month is an acceptable health risk for me. The fish oil may even have health benefits.
The Times online headline declares "Wild Salmon Is Worth The Price." The print headline is dialed back to "Away from the Farm and Into the Wild," suggesting that maybe some editor thought that the decision on whether wild salmon is worth the price should be left to the reader and the reader's family budget, rather than the dictate of some Times food writer who presumably has the benefit of declaring his wild salmon as a business expense.
