Abstract– Food preservatives are intentionally added in small quantities during processing of food to improve the taste quality and shelf-life of the food. Therefore, we are constantly exposed to different food preservatives in daily life that may or may not show adverse effects. Evaluating the cyto-genotoxicity of food preservatives is necessary. Dose dependent and Time dependent effect of Butyl hydroxylated anisole (BHA), commonly used food preservative was done at two concentrations, 0.01mg/L and 0.04mg/L. The mitotic index had been calculated for the control and treated cells. The mitotic indices at 24hrs were 71.67±1.527 for control and 69.33±2.081 and 35.33±1.527, respectively. The mitotic indices at 48hrs were 54.67±2.081 and 27.67±2.081, respectively. The best results were observed in 72 hrs where the mitotic indices were 48.33±2.88 and 18.33±2.88 at 0.4mg/L. Chromosomal abnormalities like multinucleated cells, laggard and anaphase bridges were observed. The effect of preservative BHA on the somatic cells of Allium cepa was cyto-genotoxic.
