Client Testimonials

We set out a programme of testing based on food safety analysis on water and food samples, personnel and hygiene swaps in the restaurants. CLS technically manage the programme for us. They go around to all the stores and take our samples and feed the results back to us then within a week or so.


Brian Malone, Food Safety Manager

We have 121 stores nationwide and CLS audit our stores twice a year and do microbiological testing on everything from countertop surfaces to hand personnel swaps to food samples. Their services are probably quite unique and they provide a one-to-one account manager. Their personnel are always very friendly and very professional to deal with.


Rob McEvoy, Food Safety Manager

CLS have been working with us for over 10 years and they provide us with a number of different services. This would include pre processing of shellfish samples and also the microbiological testing of shellfish. CLS also have a very high-quality standard and they work to the same kind of standards as ourselves.
