VIRSeek: Virus detection in food

VIRSeek - Background

8

Common viruses in food: norovirus, hepatitis A viru s (HAV), hepatitis E virus (HEV), rotavirus

Found on/in food products and in water

Surveillance for foodborne disease outbreaks, Unite d States Annual report (2016)

• Norovirus most common source of single-etiology outbreaks (36 %)

• 17 % of hospitalisations due to HAV

EU summary report on zoonoses, zoonotic agents and food-borne outbreaks (2016)

• 9.8 % of food outbreaks viral

• Caliciviruses caused highest number of illnesses per outbreak

• Norovirus: 31.6 cases/outbreak → 24 % of all illnesses in food outbreaks

VIRSeek – Our solution

10

Challenges for food analysis Low virus concentration in foods

No cultivation possible → concentration steps required

Certain relevant matrices may contain PCR inhibitor s

Viral process controls essential

VIRSeek RNAExtractor Food

Preparation for Real-time RT-PCR

RNA extraction from viral samples prepared and conc entrated according to ISO 15216

Silica-coated magnetic bead based extraction

Removal of potential inhibitors

Sample types include:• Soft fruits

• Leaf, stem and bulb vegetables

• Bottled water

• Bivalve molluscs

VIRSeek – Solution components

13

VIRSeek Food Murine Norovirus (MNV)

Murine norovirus • found in mice and other small animals

• not pathogenic to humans

Process control virus to monitor efficiency of viru s concentration steps

Samples spiked during virus concentration (ISO 1521 6)

Morphologically and physio-chemically similar to pa thogenic viruses• Comparable extraction efficiency

Tested in parallel to each target

VIRSeek – Solution components

14

VIRSeek Food Norovirus & HAV kits Norovirus genogroups I & II – most relevant to human health

RNA viruses without an envelope

One-step Real-time RT-PCR is used to detect the RNA of the viruses

IPC is included in order to confirm the validity of each sample

Validated for 3 cyclers:• Agilent AriaMx TM

• BioRad CFX96 Touch TM

• BioRad CFX96 Touch TM Deep Well

• Also validated and certified for kits in the BAC Gene product line
