SOME FARMED FISH: NOT MORE THAN ONCE A MONTH
People often pay more to eat fish because they’ve been told it’s good for their health. But not everything about fish is healthy. Wild-caught fish can have contaminants, but studies have shown that farm-raised fish typically have even more contaminants because they are fed a diet high in fish meal and fish oil caught in polluted waters.
The “why” is explained in detail in this summary of a global study of farmed vs. wild salmon by the Institute for Health and the Environment at the University of Albany, which notes that “in most cases consumption of more than one farmed salmon meal per month could pose unacceptable cancer risks.”
Which Fish Meal/Fish Oil is Most Contaminated?
The FDA chart below shows that not all fish meal and fish oil used by fish farms are the same.
The primary supplier of menhaden fish meal and fish oil is US-based company Omega Protein.
Which Supermarkets? You can help…
Unfortunately, we don’t know of any major supermarkets that disclose contamination levels in their fish. If you want further information, below is a list of major supermarkets. Click on the link to ask them what levels of contaminants are found in the seafood they sell and whether their suppliers use higher-contaminant feed sources, such as the menhaden from Omega Protein. If your local supermarket isn’t listed, a quick Google search of “[your supermarket name] contact us” can usually get you to their customer service department.
