Emerging Porcine adenovirus PAdV-SVN1 and other enteric viruses in samples of industrialized meat by-products

Abstract

Foodborne diseases are often related to consumption of contaminated food or water. Viral agents are important sources of contamination and frequently reported in food of animal origin. The goal of this study was to detect emerging enteric viruses in samples of industrialized foods of animal origin collected in establishments from southern of Brazil. In the analyzed samples, no Hepatitis E virus (HEV) genome was detected. However, 21.8% (21/96) of the samples were positive for Rotavirus (RVA) and 61.4% (59/96) for Adenovirus (AdV), including Human adenovirus-C (HAdV-C), Porcine adenovirus-3 (PAdV-3) and new type of porcine adenovirus PAdV-SVN1. In the present research, PAdV-SVN1 was detected in foods for the first time. The presence of these viruses may be related to poor hygiene in sites of food preparation, production or during handling.
