When I was doing the research for What to Eat (my book about food issues in which I used supermarkets as an organizing device), it was clear that the fish aisle was the Wild West of food marketing. Anything goes.
Unless you are an expert, it’s hard to tell one fish from another. Many fish sellers, alas, are not expert either.
I divided the issues into dilemmas and quandaries.
- Farmed v. wild
- Methymercury v. omega-3’s
- PCBs v. omega-3’s
- Country-of-origin labels
- Artificial seafood (surimi)
- Artificial color (salmon dyes)
The chapter I called “The Fish-Labeling Quandaries” begins:
Just about any American supermarket has a fish counter offering fresh, frozen, whole, and filleted seafood, almost certain to be bewildering in variety, quality, and price. The signs that accompany the fish do not always help much. Like other fresh foods, fish do not come with Nutrition Facts labels, but sellers are supposed to tell you what species are, whether they were previously frozen. Beginning in spring 2005, they also were supposed to tell you what country the fish came from and whether they were farmed….
A nearby…supermarket…offered a refrigerator case packed with plastic-wrapped seafood…Although the wrappings were clearly marked with the species, weight, and price, none said where or how the fish had been raised. In answer to a question about whether a piece of salmon was farm-raised or wild, a clerk replied, “I really have no idea where this thing comes from.”
…How anyone can make a reasonable choice about which fish to buy on the basis of these seemingly arbitrary and confusing labels is a mystery to me. Better labeling would certainly help, particularly of the country of origin, but you might also want to know what the fish signs really mean when they tell you that seafood is “artificial,” “color-added,” “organic,” or, for that matter, “not genetically modified.” By this time, you can guess that each of these labeling terms takes you into matters that do not precisely qualify as fish dilemmas, but do present any number of what I think are fish quandaries—puzzles you have to deal with when deciding what fish to buy.
According to the Times, fish sellers either lie or are clueless about what they are selling.
My advice: find a fish seller you can trust.
But, as I put it then and the Times article confirms, “it is not always easy or possible to know whether your fishmonger is trustworthy.”
