Russian authorities warn of parasite risks in freshwater fish handling

Authorities in the Nizhny Novgorod Region have issued a reminder on the safe handling of freshwater fish. Rospotrebnadzor, the local consumer watchdog, highlighted the risks of parasites and harmful bacteria if fish is not prepared correctly. Proper cooking and storage methods are essential to avoid serious health issues. Freshwater fish can carry dangerous parasites, including those causing opisthorchiasis, clonorchiasis, diphyllobothriasis, and anisakiasis. To reduce these risks, thorough preparation is key.

Before cooking, the fish must be gutted and cleaned. Removing the innards and gills, followed by a careful rinse, helps eliminate contaminants. For freezing, strict temperature guidelines apply: -40°C for 7 hours, -35°C for 14 hours, or -18°C for around 20 days. When cooking, boiling for 15–20 minutes is recommended. Frying fillets, if cut to 2 cm thickness, should also take 15–20 minutes. For salting, a minimum of 6% salt concentration is required, with a curing period of 14 to 40 days. These steps ensure that parasites and harmful microorganisms are destroyed before consumption.

Following these guidelines helps protect against foodborne illnesses linked to freshwater fish. The measures—from proper gutting to precise freezing and cooking—are designed to keep residents safe. Rospotrebnadzor’s advice aims to prevent infections while allowing people to enjoy fish without risk.
