The Crucial Role of Raw Milk Microbial Testing in Producing High-Quality Dairy Products

The dairy industry globally strives to meet high-quality standards for processed products. One key to achieving this is raw milk microbial testing, a meticulous monitoring process that examines raw milk’s microbiological parameters. In this blog, we review the significance of these parameters, including somatic cell counts (SCC) and bacterial counts, and their direct impact on…

Combat Microbial Spoilage: Ensuring Dairy Quality Assurance with QualiTru

The dairy industry faces the continuous challenge of maintaining the safety and quality of milk and its derivatives. Despite significant advancements in processing technologies, a 2018 paper in the Journal of Dairy Science reported that nearly half of all fluid milk products show evidence of post-pasteurization contamination with psychrotrophic or psychrotolerant spoilage organisms.1 This contamination primarily stems from…

Leveraging Sanitary Survey Sampling for In-Process Quality Control

In a typical food plant, appropriate preventive controls are implemented to address the inevitable hazards from a variety of sources to ensure that the resulting products are safe.  As part of these programs, we traditionally think of sampling ingredients or finished products to help verify the effectiveness and thorough implementation of these controls. Many food companies…

Sterile or Aseptic? Understanding the Difference

Ensuring the quality and safety of dairy and food products is the number one priority of processors, explaining why questions surrounding sterile or aseptic frequently enter into the conversation, especially when discussing equipment cleanliness and sampling or testing techniques. While the words sterile and aseptic are often used interchangeably, they are not, in fact, interchangeable….

Economics of Quality Assurance in Dairy Processing

A cost-benefit analysis of a well-conceived and carefully sustained quality assurance program for dairy processing is hard to pin down. Every month, the costs associated with maintaining quality assurance jump off the profit and loss statement, but the benefits are much harder to decipher. Still, when evaluating the economics of quality assurance over the long…

Micro Testing for Post-pasteurization Contamination (Part 3)

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…
