Proudly serving Hawaii since 1946.

HPC Foods Laboratory department was established. Introduced PCR-based molecular detection for pathogen testing in food products manufactured in-house at the Poi, Sprouts, and Produce Processing Center departments. This type of testing was also used to test the irrigation water products were grown in at the Sprouts department.

Expanded the laboratory to include a dedicated PCR testing area, designed with clearly defined zones for pre-PCR, amplification, and post-PCR activities to minimize the risk of cross-contamination. This upgrade incorporated enhanced biosafety measures, including unidirectional workflow, specialized ventilation considerations, and strict contamination/decontamination control protocols.

Introduced U.S. Environmental Protection Agency (EPA) approved, validated methods for the analysis of potable and wastewater, expanding the laboratory's capabilities to include comprehensive water testing.

Became the first laboratory in Hawaii to offer accredited food, water and environmental sample testing services. Achieved ISO/IEC 17025 accreditation through the American National Standards Institute–American National Accreditation Board (ANAB), demonstrating technical competence, validated methods, and a strong commitment to internationally recognized quality standards.

Expanded the scope of ISO/IEC 17025:2017 accreditation to include a few more validated testing methods for both food and environmental samples. This enhancement strengthened the laboratory's technical capabilities, allowing it to offer more comprehensive and reliable analytical services.
