text: The Public Analyst runs a laboratory which will:
  * Analyse food:
  ** for composition: many foods have legally defined, customary or expected  compositions
  ** for additives: which must be legally permitted and within prescribed concentrations
  ** for contamination: chemical, microbiological
  ** to assess the accuracy of labelling
  ** to investigate whether complaints by the public are justified
  * Interpret relevant law passed by the EU and UK or Ireland:
  ** act as expert witness in prosecutions
