Microbiological Criteria

 Microbiological criteria are used to assess the acceptability of food.  When a particular food is tested for a particular microorganism (toxin or metabolite) the results can indicate if:

  • the food is safe to eat or not
  • the food is of acceptability quality, or
  • the hygiene standards in the food establishment are satisfactory or unsatisfactory.

Legal microbiological criteria have been set for some, but not all, combinations of food and microorganism (toxin or metabolite).  If a relevant legal microbiological criterion does not exist, guideline microbiological criteria can be used to assess the acceptability of food.
