Darrell Bigalke

QualiTru Sampling Systems, formerly known as Quality Management Inc. (QMI), was founded in 1983 by Darrell Bigalke. After ten years with Ecolab, he seized the opportunity to carry the QualiTru technology to support his dairy food safety consulting business. Drawing from his extensive knowledge of the dynamics of microbial contamination, he played a central role in helping shape the establishment and adoption of the new testing standards in the dairy industry after two dairy-related tragedies that occurred in 1985.

Mr. Bigalke focused his new company on the singular mission of promoting aseptic sample testing for the dairy industry, extending far beyond final product testing, which is limited in identifying in-process risks, such as biofilms, and cannot lead to process improvements.

Today, QualiTru’s systems are considered the most trusted method for gathering aseptic and representative milk samples for testing and are used by thousands of large dairy farms, haulers, and food processing plants across the U.S. and in over 30 countries worldwide.

Global Presence

QualiTru provides a unique combination of aseptic and representative sampling that is not offered by anyone else.

QualiTru is investing in new markets, technologies, partnerships, and employees to help the dairy and liquid food industries produce the safest and best quality food. The company has increasingly partnered with universities to research sampling best practices and conducted field case studies to enable farmers and quality professionals to obtain the most accurate and representative process data. The website emphasizes science-backed solutions, providing invaluable resources for dairy and liquid food industry customers.

Despite its growing success as a global entity over these past decades, everyone working at QualiTru today has remained steadfast to Mr. Bigalke’s original vision and mission: to protect consumers by providing the equipment and expertise for accurate and representative sampling that helps the dairy and liquid food industries produce safe, high-quality products.
