Impedimetric Determinaton of Total, Mesophilic and Psychrotrophic Zounts in Raw Milk

A rapid impedimetric determination for total, mesophilic and psychrotrophic counts in raw milk showed correlations (between impedance detection times and standard plate counts) of ‐0.96, ‐0.95, and 0.96, respectively. Mesophiles were most often seen as the predominant population, the impedimetric method allowed for these samples containing above 1.0 × 10 5 CFU/ml to be screened out within 4 hr. Psychrotrophic levels of 1 × 10 5 CFU/ml and above were screened within 21 hr, while total concentration of samples containing above 1 × 10 5 CFU/ml were screened within 16 hr.
