In US FDA/CFSAN- Bacteriological Analytical Methods Online,
"Aerobic Plate Count; Computing and recording counts (see refs 6, 8), was stated " All plates with fewer than 25 CFU. When plates from both dilutions yield fewer than 25 CFU each, record actual plate count but record the count as less than 25 x 1/d when d is the dilution factor for the dilution from which the first counts were obtained." Refers to USP Microbial Limit Test; Total Plate Count Method, The minimum dilution of the method is 1;10, so the minimum number of CFU is < 25X10 (< 250)CFU. How about Microbial limit testing of material that has microbial limit < 100? Best Regards,
