There is an increasing number of alerts and reported outbreaks of foodborne viruses in foods. Viruses mostly associated with viral foodborne illnesses and outbreaks are Norovirus (NoV) and Hepatitis A virus (HAV).
Noroviruses have been recognized in Europe as a leading cause of foodborne gastroenteritis over the last decade. HAV causes very severe inflammation of the liver (hepatitis). However, HAV is prevailing in endemic countries outside Europa. It should be taken into consideration when importing food products originating from these countries. The WHO provides a map with an overview of the estimated Hepatitis A virus prevalence.
Major contamination routes are person-to-person or person-to-food (during picking, preparation of food) and contaminated water (e.g. applied as irrigation water, washing water, to dilute pesticides or cultivation water).
A broad range of foods have been implicated in NoV/HAV foodborne outbreaks:
- shellfish (e.g. oysters, mussels), crustaceans and their products;
- fruits - mainly berries - and vegetables (fresh and frozen);
- unpasteurized fruit and vegetable juices;
- ready-to-eat food such as sandwiches.
There is actually no European legislation in place for Norovirus and Hepatitis A virus in fresh produce. However there are scientific opinions made by EFSA.
NoV/HAV detection is still difficult and hampered by several limitations. Unlike most foodborne bacteria, viruses cannot grow in the environment since they need specific host cells to replicate. In general, the strategy for detection of foodborne viruses in food samples consists of 3 steps.
For the samples, we talk mainly about fresh produce and fruits and about processed fruits and vegetables.
Primoris is officially accredited for norovirus and hepatite A viruses. The accreditation certificate can be consulted on this website.
The summer months are in the air. If you are soon leaving for holidays, we wish you a pleasant and enjoyable time off. Also during the summer months you can continuously count on the services of Primoris.
Primoris is aware of its social role and as a specialised lab for residue and contaminant analysis in the agri-food sector it contributes to an improved food safety. Nonetheless, Primoris wants to go one step further and give back a little extra to society together with our customers and employees.
Due to the commision implementing regulation (EU) 2017/2091 of 14 November 2017, the approval of the active substance iprodione will not be renewed as from 5 March 2018.
As from Monday January 29th, we extend our services with highly reliable and accredited analyses of the mineral oil hydrocarbons (MOH) in food:
- MOSH: mineral oil saturated hydrocarbons
- POSH: polyolefinic oligomeric saturated hydrocarbons (closely related to MOSH. POSH & MOSH are always reported together)
- MOAH: mineral oil aromatic hydrocarbons
