Detection of adenovirus, rotavirus, and hepatitis E virus in meat cuts marketed in Uruguaiana, Rio Grande do Sul, Brazil


The aim of this study was to investigate the presence of adenovirus (AdV), rotavirus (RV), and hepatitis E virus (HEV) in beef, pork, and chicken meat cuts in retail trade in the city of Uruguaiana, RS, Brazil. A total of 131 meat products were collected (beef, n = 55; chicken, n = 47; pork, n = 29) from 18 commercial establishments (supermarkets, n = 7; butchers, n = 7; markets/grocery stores, n = 4). All samples were evaluated for AdV, RV, and HEV. The genomes of RV and AdV were identified in 29% (n = 38) and 5.34% (n = 7) of the samples, respectively. HEV was not identified in any of the samples. Chicken cuts had a higher frequency of AdV and RV isolates compared to beef and pork (P < 0.05). Among the categories of commercial establishments evaluated, all revealed at least one positive sample for AdV and RV; however, supermarkets showed a higher frequency of RV than others (P < 0.05). The genetic material of AdV and RV was identified simultaneously in 2.29% (n = 3) of samples from supermarkets (n = 2) and grocery stores (n = 1). This is the first report on detection of enteric viruses in meat cuts in the western region of the state of Rio Grande do Sul, Brazil, and the presence of AdV and RV in these products may indicate flaws during the process of handling these foods, especially in places where commercialization provides important public health issues.
