Microbiological analysis

The testing facility for microbiological research offers microbiological analysis services for the food and animal feed industry.

The measurements can be used to:

  • Assess the freshness of raw materials
  • Estimate the product’s shelf-life
  • Assess hygiene in the treatment of foodstuffs and personal hygiene

 

The following measurements are among those available with no particular prior notice

Measurements labelled with an asterisk (*) do not have accreditation.
