With virus testing, it must be considered that there are no safe limits: a few viral particles may be sufficient to cause human outbreaks.

Foodstuffs and food surfaces are highly complex matrices. Mérieux NutriSciences offers virus extraction techniques optimized according to the properties of the matrix. We integrate a full spectrum of services specifically related to virus detection, ranging from routine surveillance to training food handlers to meet hygiene requirements.

For years, difficulties in propagating viruses in cell cultures greatly hindered their detection in food. Advanced molecular approaches have considerably improved detection, with Real Time (RT) – PCR becoming a standard method worldwide.

Mérieux NutriSciences offers fast and reliable testing for Norovirus GI / GII and Hepatitis A testing in the following matrices:

  • Drinking water
  • Food Contact Surfaces

The initial contact of the virus with the food may occur at any time during food production (e.g. before harvesting, during processing, at the time of preparation). Having mechanisms in place to rapidly address the probability and possible consequences should be a priority. It is far better to focus on preventive measures to avoid viral contamination rather than trying to remove/inactivate viruses from food

Our Food Testing and Water Testing services also include a full range of virus detection tests.
