In 1992 Thompson's was the first feed mill in Europe to achieve the International Quality Assurance  Standard, ISO9002, for its entire manufacturing process. This quality standard is the foundation of a comprehensive quality assurance programme operated by Thompson's from raw material sourcing , through manufacture to the delivery of finished feeds to farms.

In 1998 Thompson's was the first mill within the British Isles to achieve HACCP (Hazard Analysis Critical Control Points) Accreditation which, in common with all our other Quality Control Systems, is independently verified by accredited auditors from Lloyds. HACCP Quality Control Systems are widely used in the food industry and are appropriate for Thompson's' manufacturing processes.

Thompson's, since 1999, have been a registered manufacturer of organic animal feeding stuffs under the United Kingdom Register of Organic Feed Standards (UKROFS). Thompson's are the biggest user of both local and imported organic raw materials in Northern Ireland.

To constantly monitor and control quality, the group operates two UKAS accredited laboratories for microbiological examination and chemical analysis. These laboratories support our independently audited Quality Assurance Standards which operate across our entire business. Access to Group facilities ensures speedy availability of results whilst Near Infrared Spectrophotometry (NIR) technology offers interactive quality control analysis of both raw materials and finished feeds, available to both our Nutritional Department and Customers.

The UKASTA Feed Assurance Scheme, designed for manufacturers of compound animal feeding stuffs and premixtures, provides a set of principles and guidelines for the safe production and supply of feed to livestock producers. The UKASTA Feed Assurance Scheme (UFAS) is supported by ABM (Assured British Meat) and NIGTA (Northern Ireland Grain Trade Association). Inspections are carried out by experienced independent verifiers, who audit for compliance with the UKASTA Code of Practice.
