^aFetal bovine serum was added to FdCa (OH)₂ solution so as to represent 5% organic materials of total volume.

^bThe titer converted into an index in log₁₀ of bacteria control.

^cThe titer in log₁₀ that added blocking solution before Salmonella infantis or E. coli.

^dThe titer converted into an index in log₁₀ of the recovered bacteria after indicated time of treatment, such as 1 min, 3 min, and 5 min.

^*Inactivation regarded as effective when RF was ≥3. E. coli=Escherichia coli, RF=Reduction factor, CFU=Colony-forming units, tpc=Titer of bacteria/virus control, FBS=Fetal bovine serum, FdCa (OH)₂=Food additive grade calcium hydroxide
