Meat is an animal flesh utilised as food which also serves as the cardinal protein source vide its component elements and amino acids. Despite this, meat wholesomeness has recently been mutilated for its perceived association with polycyclic aromatic hydrocarbons (PAH) in smoked products and heterocyclic aromatic amines (HAA) in cooked products. Hence, this study was aimed at assessing the biological effects, nutritional value and safety of the differently processed beef steaks. Weanling male Wistar rats (n=63) weighing 55±1.9g were allotted in a completely randomized design to six treatments with ten rats per treatment. The rats were assigned to individual metabolic cages and had free access to water and assigned experimental diets ad-libitum for 21 days. Feed intake of rats on RBS (57.66 g) was significantly higher (p<0.05) than those on BSBS (56.02 g), SBS (50.10 g) and DFBS (46.00 g). Biological value of 91.46 % in rats on DFBS was higher than 89.17 % for RBS, SBS (88.59 %) and BSBS (87.46 %). Moderate fat deposition and scanty infiltration were noticed in the liver rats on DFBS and SBS, respectively. There were observable vascular congestion and tubular necrosis in the kidney of rats on DFBS. Rats on DFBS had fat infiltration in epicardia layer and vascular congestion. Consumption of DFBS altered kidney structure, caused fat infiltration and congested valves of rats. Therefore, dietary DFBS could heighten the risk of liver, kidney and heart diseases
