Sodium benzoate (SB) is one of the most widely used additives in food products in the world. The aim of this study was to assess the effect of three different concentrations of SB on the DNA breakage in liver cells and on the micronuclei formation and the mitotic index in lymphocytes of pregnant rats and their fetuses, as well as to evaluate the effects of SB on the fetus development. The results showed that general genomic injuries were present in almost all the liver cell samples obtained from the SB group compared with the control (non-treated) group. This indicates that SB usage may cause DNA damage and increase micronuclei formation. We recommend that pregnant women should avoid consuming foodstuffs containing SB as an additive.
