The institute issues a warning to pregnant women about certain fish types.
Consuming certain types of fish, particularly tuna, could pose a health risk to pregnant women and infants, according to the Federal Institute for Risk Assessment (BfR). This is due to the presence of a mercury compound called methylmercury, which accumulates in fish, mollusks, crustaceans, and squid. Although methylmercury doesn't typically pose health issues for most people, it can have adverse effects on the neurological development of unborn children and infants.
Dr. Andreas Hensel, the President of BfR, advised pregnant women and nursing mothers to abstain from specific fish species to minimize their exposure to methylmercury. The highest concentrations of this compound are found in large and older predatory fish, such as shark, swordfish, or tuna, and also in red snapper. BfR's research demonstrated that these fish contain significant amounts of methylmercury.
Methylmercury forms naturally when bacteria transform inorganic mercury compounds into organic ones. This compound can enter the food chain and reach humans, regulates the BfR. Nevertheless, it's important to highlight the health benefits of fish consumption, which include supplying vitamins, trace elements, and specific unsaturated fatty acids.
The BfR and the German Nutrition Society further advise pregnant women to steer clear of raw fish and raw seafood, commonly used in sushi and sashimi. Raw fish and seafood are potential carriers of Listeria bacteria, which, if severe, can result in miscarriage, premature birth, or infection of the newborn. So, for the well-being of the mother and her child, avoid consuming them.
The BfR's findings emphasize the importance of altering consumption habits to ensure the balance between avoiding methylmercury-rich fish and enjoying the health benefits of fish. This requires consideration of specific fish types, cooking methods, and food sources.

Despite the health benefits of fish consumption, such as providing vitamins and unsaturated fatty acids, pregnant women should avoid certain types, particularly large and older predatory fish like shark, swordfish, tuna, and red snapper, due to their high methylmercury levels. This compound, which forms naturally and can enter the food chain, poses a health risk during pregnancy and can negatively impact the neurological development of unborn children.
