Milk Microbiology and Quality Analyses
Cows and Bulk Tanks
4-Bact Analysis Microbiology Test: Raw milk quality testing that includes microbiological assays where the same sample is plated for Coliform, Aerobic plate count, PI (pre-incubated) count and LPC (Lab Pasteurized count)
Standard Plate Count (SPC): Aerobic plate count of total colony forming units of bacteria per milliliter or gram of raw, processed liquid and dry dairy products utilizing “SMEDP” 17th edition.
Lab Pasteurized Count (LPC): Raw milk in test tubes heated to 62.8C +/- 0.5C, survivors counted by standard plate count method utilizing “SMEDP” 17th edition.
Pre-Inc Plate Loop Count (PI): Raw milk sample undergoes preliminary incubation at 21 degrees Celsius for 18 hours before analysis to stimulate the growth of psychrotrophic organisms and subsequently a Plate Loop Count (PLC). Is performed utilizing “SMEDP” 17th edition.
Mastitis Culture Analysis (cow, sheep, goat) : Examination of mingled whole cow or individual quarter samples for presence of contagious and environmental bacteria.
Bedding Culture: Analysis of bedding materials for presence of environmental microorganism contaminants.
Sediment Testing: : Quantitative determination of amount of insoluble extraneous material in a representative sample of milk, utilizing “SMEDP” 17th edition; 15.072 and CFR 58.2728
Mycoplasma Culture Analysis: Cultivation and selective isolation of mycoplasma
Yeast and Mold Plate Analysis: Determination of yeast and mold cell forming colonies in a dairy sample under specified conditions utilizing “SMEDP” 17th edition.
Antibiotic Testing: Delvo, Charm II, Charm SL, HPLC
Johnes Culture Test: Fecal culture testing for Johnes (or Johnes Elisa test)
