Lawsuit alleges negligence in resort norovirus outbreak

The statement of claim alleged the resort acted with a “wanton, callous and reckless regard” for the safety of the class members who are seeking $5 million for negligence and breach of contract.


With the ceeramTools assays for detecting and identifying NOROVIRUS in any type of food matrices and Surfaces, it is now possible to anticipate and organize regular controls with your molecular laboratory.


Genogroup I and II noroviruses are non enveloped and single strand RNA viruses. These human enteric viruses are responsible for most of viral gastroenteritis outbreaks. They are pathogenic for all age groups of the population. These viruses are very infectious; one to ten viral particles are sufficient to get sick. Their mode of transmission is the feco-oral route. After excretion in human stool, due to their structural properties, noroviruses can resist to different physical and chemical treatment.
 Adsorbed on particles, they can survive in different kind of environment for a long period. Food samples can be contaminated via food handlers or by the environment. Due to their structural properties, norovirus can survive to different food process. The consumption of contaminated food can lead to human outbreak. There is no cell culture system available for the multiplication of human noroviruses.

Detection of noroviorus

The detection by ELISA is not recommended due to norovirus genetic diversity and its lack of sensitivity. Molecular techniques (real time RT-PCR) are the methods of choice for NoV detection after extraction and viral RNA purification from the sample.

Norovirus detection kits

Detection kit is based on real-time PCR. Real-time PCR is a proven method for pathogen detection and has been applied successfully to a wide range of foodborne pathogens. The method tests for food pathogens by amplifying and detecting a RNA target sequence that is specific to Norovirus. Detection is quick, simple, and with outstanding sensitivity and specificity. Shelf-Life : 360 days.
