Residents of Saransk told about the remains of mercury and medicines found in fish

In Saransk, residents were told that some types of fish can be more harmful than sausages. Farmed fish can accumulate antibiotics, heavy metals and other dangerous compounds.

The list of unwanted purchases included pangasius and tilapia. Also on the list were farmed salmon and tuna. Salmon gets a pink hue due to dyes and is often treated with antibiotics, and tuna accumulates mercury, dangerous for children and pregnant women.
