Effective Micro Program: Understanding the Microbiological Tests (Part 4)

ByNeil Bogart

Throughout this series on dairy microbiological testing, we have discussed the types of micro tests that can be used to enumerate the classifications of bacteria we are concerned with in fluid milk processing. The first two articles discussed Gram-negative bacteria in raw milk and the effects of Gram-positive heat resistant thermoduric/psychrotrophic spore formers (HRSF) on…

Micro Testing for Post-pasteurization Contamination (Part 3)

ByNeil Bogart

The first article in this series, Raw Milk Dairy Micro Testing, focused on Gram-negative bacteria in raw milk with the Preliminary Incubation (PI) Count and Fresh Standard Plate Count (SPC) tests. The second article, The Effects of Gram-positive HRSF Bacteria on Fluid Milk Shelf Life, discussed another classification of bacteria that was not known as…
