Frozen beef kofta samples showed relatively higher mean values of APC, coliform count and S.aureus count as 3.08×105± 0.21×105; 1.57×103± 0.15×103 and 2.82×103± 0.39×103 CFU/g , respectively than other products. Meanwhile, the enterotoxins secreted by S.aureus were enterotoxin B and enterotoxin (A&D), enterotoxin A, enterotoxin D and enterotoxin (A&C).
