Using Preliminary Incubation Count for Measuring Raw Milk Quality

The Preliminary Incubation (PI) Count for measuring the quality of raw milk has become increasingly popular since the production of quality milk is the number one goal of dairy farmers and cooperatives. The PI test is especially sensitive to psychrotrophic bacteria. These particular bacteria can grow at colder temperatures, which is why dairy processors are encouraging…

Bacteriophage Control Using Closed Bulk Starter Vessel Inoculation – Part 2

Bacteriophage control and management for preventing phage invasions are challenges many dairy processing plants face. Starter culture bacteria play an essential role by converting milk sugar (lactose) into lactic acid in making dairy products such as cheese and yogurt.

Using Bulk-Tank Somatic Cell Counts for Monitoring Milk Quality and Udder Health

Bulk-tank somatic cell counts (BTSCCs) are measured and monitored from Federal Milk Marketing Orders (FMMOs) to determine the quality of the milk supply in the U.S. BTSCCs are defined as the number of white blood cells, secretory cells, and squamous cells per milliliter of raw milk. Milk processors monitor BTSCCs in the nation’s milk shipments…

Impact of Bacteriophages in Dairy Processing – Part 1

The quality of milk can be negatively impacted by multiple sources of contamination in a dairy processing plant. Previous blogs focused primarily on microbial contamination of raw milk caused by various bacteria. For products such as cheese and yogurt, starter culture bacteria play a positive and essential role. However, the fermentation function of starter cultures can be threatened by another microbial contamination, bacteriophages, or phages as…

Bovine Viral Diarrhea (BVD)—Testing, Detecting, and Managing

Bovine Viral Diarrhea (BVD) can have a devastating impact on dairy herds. Management of the disease requires a comprehensive program of vaccinations and monitoring. Persistent infection (PI) carriers of the Bovine Viral Diarrhea Virus (BVDV) can pose a real and ongoing threat to overall herd health. The Cornell Animal Health Diagnostic Center’s website indicates that…

Psychrotrophic Bacteria in Pasteurized Milk—Spoilage, Testing, and Line Sampling

Bacteria in pasteurized milk is the leading cause of spoilage and reducing shelf-life. Refer to my earlier posts, How Bacterial Generation Times Impact Fluid Milk Quality and Shelf-life and Heat-Resistant Psychrotrophic Bacteria and Their Effect on the Quality of Pasteurized Milk. In those posts, I discussed the collective efforts of the dairy industry and regulatory…
