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:

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
