Question
Kousei works at a company that produces sweetened condensed milk. If one or more samples exceed 1 x 10 fungal CFU/mL (or CFU/g) the entire lot produced will be rejected. Kousei's boss, Kaori, wanted to know if the lot passed the FDA guidelines. The following fungal counts were obtained after serial dilution and spread plating of the samples: Type of Dilutions plated 10-4 10-3 105 Colony Plate 1 Plate 2 Plate 1 Plate 2 Plate 1 Plate 2 Plate 3 166 Fungi 160 155 45 40 1 11 Based on the fungal counts obtained, will the lot be rejected? No, because the computed CFU/mL is 4.3 x 10^5 No, because the computed CFU/mL is 4.1 x 10^5 Yes, because the computed CFU/mL is 4.3 x 10^6 Yes, because the computed CFU/mL is 4.1 x 10^6 Yes, because the computed CFU/mL is 1.1 X 10^7 Information is lacking so CFU/mL cannot be computed Plate 3 37 Plate 3 7
