In plants (A. C. E and G) using wheat flour as a raw material, the numbers for APCs (1.1-2.6 log CFU/g, mean of 7 plants= 1.9 log CUF/g) LAB (ND or 2.1 log CFU/g in plant G), fungi (ND or 2.7 log CFU/g in plant G) were generally lower than in those using rice. AAB, coliforms and B. cereus were not detected in any wheat flour sample.
