Economics of Quality Assurance in Dairy Processing
ByClarence Johnson November 13, 2023June 7, 2024

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…

Preventing Post-Process Contamination: Don’t Lose Sight of the Basics
ByRuth Petran September 8, 2023May 6, 2024

With the World Health Organization estimating that one in ten people get sick and more than 400,000 die from foodborne illnesses each year, a public health focus aimed at decreasing this incidence is needed. The primary goal of the management of risks associated with food is to protect public health by controlling them as effectively…

Effective Micro Program: Understanding the Microbiological Tests (Part 4)
ByNeil Bogart June 20, 2023May 29, 2024

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…

Why is Aseptic Inline Sampling Critical to Process Monitoring?
ByMara Herschbach January 9, 2023June 27, 2025

The significant food safety recalls that have occurred in the dairy processing industry this past year, ranging from Listeria outbreaks in ice cream to Cronobacter in infant formula, and the Food and Drug Administration’s* (FDA’s) recent publication of its revised Investigations Operations Manual draw attention to the criticality of inline process monitoring of bacterial risks,…

Membrane Filtration Sampling
ByChris Pundmann November 15, 2022May 6, 2024

Membrane filtration is a widely used process in the dairy industry that separates specific components of milk and whey and then either concentrates or removes/reduces them. The technology used in cheese-making, whey protein concentration, fractionation of protein, and numerous other dairy processes requires special sampling considerations for both regulatory purposes and component analysis. It is…
