G.S. DUNN LIMITED
Quality Assurance

Being the premier miller of mustard products in the world demands a strong focus on product quality. Our fully-staffed lab of technicians and lab manager are available at any time to answer any questions concerning product quality, specifications or product development.

Incoming seed is selected according to G.S. Dunn specifications, that are more stringent than the Canadian Grain Commission Grading Standards, thus milling a higher quality finished product.

Continuous on-line sampling of finished product supplies our quality department with retained samples of every pallet of product shipped from our mill. Each bag or carton on every pallet is independently code dated for tracking, and retained samples of each pallet are kept on-site for a minimum of 1 year.


All seed is sterilized as it enters our facility. Only steam sterilization is used. The fact that we are a custom miller means that we select the correct seed for each order received, and follow the customer's specification when supplied.

Chemical and micro analysis is completed on-site for each product. This consists of SPC'S, Y&M, particle size, fat, moisture, protein, Coliform and E.Coli. Samples are monitored for salmonella and aflatoxins analysis and C of A's are available on request.

On-line magnets, accompanied by ferrous and non-ferrous metal detectors in the packing area, prevent costly returns. Our premises are protected under the ABELL Plus Integrated Pest Management Program.
