Hygiena has completed its acquisition of DuPont Diagnostics, the global food safety diagnostics business of DuPont for an undisclosed sum.

The Warburg Pincus portfolio company specializes in rapid food safety and environmental sanitation testing.

Hygiena will now sell the former DuPont Diagnostics products under the Hygiena brand through its entity, Qualicon Diagnostics.   

We are excited to welcome the team to Hygiena and look forward better serving our global food and beverage customers by offering a wider food safety testing portfolio,” said Steven Nason, CEO, Hygiena.

Hygiena now offers testing to cover the full food manufacturing process, from sanitation monitoring to finished products. With the growth of our worldwide team, we can now offer greater service and support around the globe.

We are excited to continue investing in new product research and development and further expand our product portfolio through acquisitions.”

Following the acquisition, Hygiena’s portfolio of food safety diagnostics products will now include DuPont Diagnostics’ business assets, including the BAX System, RiboPrinter System, Lateral Flow System, StatMedia and Dehydrated Culture Media product lines.

Its own product portfolio includes ATP monitoring systems, PCR-based pathogen detection and characterization systems, allergen tests, environmental collection devices, and more.

Operations will continue at DuPont Diagnostics’ Wilmington, Delaware facility and retain the staff.


DuPont and The Dow Chemical Company are in the process of merging into DowDuPont and separating the company into three areas: agriculture, material science and speciality products.

DuPont Diagnostics provides microbial detection and monitoring products that identify and characterize pathogens and other organisms in ingredients, finished products and production environments.

Earlier this year Warburg Pincus invested in Hygiena saying the company represents a platform to consolidate the highly fragmented food and life sciences testing and environmental sanitation industry.  

The private equity firm said the ATP market is expected to continue to grow due to increased regulation, the shift towards ready-to-eat and organic foods and new applications in healthcare and industrial markets
