“…In SH, Suffredini et al and La Rosa et al [ 32 , 33 ] reported much higher prevalence of HEV contamination with values ranging up to 8.1%. The prevalence of GV contamination, although considerably lower than SH, was never estimated to be 0% in other studies [ 18 , 37 , 38 ]. These considerations suggest that the role of SH and GV for HEV transmission in the Italian population may be more important than our study showed.…”

“…In the food chain, HEV has been detected in pork foods such as dry and fresh sausages at retail level [ 29 , 30 , 31 ] but also in shellfish sampled in the production areas or in biomonitoring points [ 32 , 33 ], at retail [ 34 ] or in biomonitoring points [ 35 ]. Observational studies conducted in several countries also documented HEV contamination of vegetables and fruits [ 18 , 36 , 37 , 38 ]. HEV RNA was found in sewage and surface water samples, suggesting possible environmental contamination via recycled water [ 33 , 39 , 40 ].…”

Hepatitis E is considered an emerging foodborne disease in Europe. Several types of foods are implicated in the transmission of the hepatitis E virus (HEV) to humans, in particular, pork and wild boar products. We developed a parametric stochastic model to estimate the risk of foodborne exposure to HEV in the Italian population and to rank the relevance of pork products with and without liver (PL and PNL, respectively), leafy vegetables, shellfish and raw milk in HEV transmission. Original data on HEV prevalence in different foods were obtained from a recent sampling study conducted in Italy at the retail level. Other data were obtained by publicly available sources and published literature. The model output indicated that the consumption of PNL was associated with the highest number of HEV infections in the population. However, the sensitivity analysis showed that slight variations in the consumption of PL led to an increase in the number of HEV infections much higher than PNL, suggesting that PL at an individual level are the top risky food. Uncertainty analysis underlined that further characterization of the pork products preparation and better assessment of consumption data at a regional level is critical information for fine-tuning the most risky implicated food items in Italy.

“…41 , 42 HAdV resistance to adverse environmental conditions as well as the absence of seasonality of these viruses reinforced their use as indicators of human fecal contamination in environmental samples, 12 , 17 , 43 unlike NoVs, detected in association with outbreaks. 44 , 45 Virus detection in tomatoes was described previously in Italy when NoV GII contamination was detected in commercially available tomatoes 46 and when a consumption of dried tomatoes contaminated with HAV resulted in fulminant hepatitis. 47 …”

This study aimed to evaluate the elution-concentration methodology based on skimmed milk flocculation from three varieties of tomatoes (Solanum lycopersicum L. [globe], Solanum lycopersicum var. cerasiforme [cherry] and hybrid cocktail [grape tomato]) for further monitoring of field samples. Spiking experiments were performed to determine the success rate and efficiency recovery of human norovirus (NoV) genogroup II, norovirus murine-1 (MNV-1) used as sample process control virus and human adenovirus (HAdV). Mean values of 18.8%, 2.8% and 44.0% were observed for NoV GII, MNV-1 and HAdV, respectively with differences according to the types of tomatoes, with lower efficiency for cherry tomatoes. Analysis of 90 samples, obtained at commercial establishments in the metropolitan region of Rio de Janeiro State, revealed 4.5% positivity for HAdV. Bacterial analysis was also performed with no detection of Salmonella spp., L. monocytogenes and fecal coliforms. Data demonstrated that the skimmed milk flocculation method is suitable for recovering HAdV from tomatoes and highlights the need for considering investigation in order to improve food safety.
