Lack of evidence so far for Noroviruses in food samples collected on cruise ships sailing the Mediterranean waters


Costanzo, N; Santoro, A; Peretti, V; Proroga, Y; Sarno, Elenora (2015). Lack of evidence so far for Noroviruses in food samples collected on cruise ships sailing the Mediterranean waters. International Food Research Journal, 22(5):1801-1805.

Abstract

Closed living spaces like cruise ship settings create an environment in which enteric viruses including Noroviruses (NoVs) can easily spread and outbreaks readily occur. The contribution of sources other than common confirmed vehicles to foodborne illness in cruise ships was investigated. None of the 189 collected samples (including meat, fish, buffet meals, fruits, vegetables etc.) tested by real-time RT-PCR (ISO/TS 15216-2:2013) reveled NoVs genome. Naturally contaminated food items other than shellfish have been demonstrated to be cause of NoVs infection thus, our results could neither indicate nor exclude food items as possible vehicle of infection. Reducing risk factors associated with NoVs outbreaks (contaminated raw ingredients, cross contamination, infected food handlers, inadequate temperature controls, heat treatments) is always strongly recommended.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
