You'd think that labeling something "organic" is pretty straightforward, as the standards are widely accepted and easily applied. It's not the same for "natural," a much misused label that has no standard and no enforcement, with the result that it has no meaning when used by so many corporate food processors.
Fish should be easier to label especially if caught in the ocean...it's free-range and unlikely to have added antibiotics or hormones. But in reality there is no standard, as this story from the Organic Consumers Union notes, "Fish can't be certified organic in the United States, because federal rules governing organic foods don't cover fish."
The short answer is that the "organic" fish are farmed salmon, from British Columbia and Scotland. Their producers say the salmon are being raised in a cleaner environment with more room to swim than most farmed fish. They get better food; some even eat certified organic feed. They're not given antibiotics or hormones. Chemicals aren't used to clean their nets.
The Center for Food Safety is concerned as well:
[It] today sent letters to the Attorneys’ General of 49 states urging the top state law enforcement officials to take action against the misleading practice of labeling seafood imports as “organic.” The state-based effort to protect the integrity of organic food labels is a follow up to the complaints filed by the Center last year with the USDA and Federal Trade Commission. To date, these federal agencies have left the complaints unanswered, while U.S. consumers are increasingly confronted with imported seafood misleadingly labeled as “organic”, despite the fact that there are no U.S. organic seafood standards in place.
In today’s action, the Center for Food Safety calls upon USDA to prevent consumer deception by enforcing existing organic labeling laws and regulations until new standards are finalized. The Center, which is joined in this effort by Food & Water Watch, has identified the practice of allowing seafood to be labeled as “organic” in absence of regulations as unfair, deceptive and misleading - a violation of the states’ consumer deception and misrepresentation laws.
“Allowing importers to label their seafood ‘organic’ when it does not have to meet any U.S. standards is a disservice to American consumers, who have come to trust and believe in the organic label,” said Joseph Mendelson, Legal Director of the Center for Food Safety. “USDA’s refusal to stop importers from calling their products organic when many of them use antibiotics, parasiticides, or feed that would not be permitted under U.S. regulations is dishonest. Consumers have the right to know that the labeling on their food is truthful and accurate and we’re asking the states to protect that right.”
