A Food Safety Programme

The Food Safety Programme at CLS was developed in response to a need by Food Business Operators to effectively verify their food safety management systems, HACCP and cleaning programmes.

The Food Safety Programme involves trained staff taking a predetermined number of food, water samples and hygiene swabs on site. A nationwide refrigerated collection service is provided for samples. Microbiology analysis is carried out in CLS’s INAB accredited testing laboratory Reg. No. 108T and the results are reported directly back to the client. Each programme can be tailored and allows each food business operator to comply with microbiological criteria and this criteria can then be used to validate and verify their food safety management system and their cleaning programmes.

Food Safety Programmes, are carried out by CLS for Food Business Operators across Ireland.

CLS Food Safety Programme includes the following samples:

  • Product Samples
  • Water Sample
  • Ice Sample
  • Personnel Swabs
  • Hygiene Swabs
